Kant's philosophy promises to explain various synthetic a priori claims. Yet, as several of his commentators have noted, it is hard to see how these explanations could work unless they themselves rested on unexplained synthetic a priori claims. Since Kant appears to demand explanations for all synthetic a priori claims, it would seem that his project fails on its own terms. I argue, however, that Kant holds that explanations are required only for synthetic a priori claims (...) about (purportedly) experience-independent entities, and that his project rests on a rationalist method of reflection that justifies certain basic synthetic a priori claims.

The present paper deals with the ontological status of numbers and considers Frege ́s proposal in Grundlagen upon the background of the Post-Kantian semantic turn in analytical philosophy. Through a more systematic study of his philosophical premises, it comes to unearth a first level paradox that would unset earlier still than it was exposed by Russell. It then studies an alternative path, that departin1g from Frege’s initial premises, drives to a conception of numbers as synthetic a priori in a (...) more Kantian sense. On this basis, it tentatively explores a possible derivation of basic logical rules on their behalf, suggesting a more rudimentary basis to inferential thinking, which supports reconsidering the difference between logical thinking and AI. Finally, it reflects upon the contributions of this approach to the problem of the a priori. (shrink)

We focus on Timothy Williamson’s recent attack on the epistemological significance of the a priori–a posteriori distinction, and offer an explanation of why, fundamentally, it does not succeed. We begin by setting out Williamson’s core argument, and some of the background to it and move to consider two lines of conciliatory response to it—conciliatory in that neither questions the central analogy on which Williamson's argument depends. We claim, setting aside a methodological challenge to which Williamson owes an answer, that (...) no satisfactory such reconciliation is in prospect. Rather, as we then argue, —and it is on this that we base our overall negative assessment of his argument—Williamson’s core analogy is flawed by an oversight. We conclude with some brief reflections on Williamson’s ideas about the imagination as a source of knowledge. Our principal conclusion is only that Williamson’s argument fails to perform as advertised. A constructive case for confidence, to the contrary, that the intuitive contrast between a priori and a posteriori reflects something of fundamental epistemological significance is prefigured in our final section, but will not be elaborated here.

1. EXPLICATING THE CONCEPT OF REFLECTION (under review) -/- To understand how ‘reflection’ is used, I consider ordinary, philosophical, and scientific discourse. I find that ‘reflection’ seems to refer to reasoning that is deliberate and conscious, but not necessarily self-conscious. Then I offer an empirical explication of reflection’s conscious and deliberate features. These explications not only help explain how reflection can be detected; they also distinguish reflection from nearby concepts such as ruminative and reformative (...) reasoning. After this, I find that reflection is not obviously limited to only practical or only theoretical reasoning. The chapter ends with reasons to prefer ‘unreflective’ and ‘reflective’ to dual process theorists’ labels about systems or types. -/- 2. BOUNDED REFLECTIVISM & EPISTEMIC IDENTITY (in Metaphilosophy) -/- Reflection features centrally in philosophy (e.g., Korsgaard, 1996; Rawls, 1971; Sosa, 1991) and psychology (e.g., Pennycook, 2018). Bounded reflectivism is an empirically adequate model of reflection that explains reflection’s capacity to either help or hinder reasoning—e.g., reflective equilibrium vs. reflective polarization (e.g., Kahan et al., 2017). One innovation of the model is epistemic identity: an identity that involves particular beliefs—e.g., religious and political identities. When we feel that our epistemic identity is threatened, we can reflectively defend its beliefs rather than update our beliefs according to the best arguments and evidence. The solution, I argue, is not to suppress epistemic identity but embrace it by appealing to shared, superordinate epistemic identities. -/- 3. ALL MEASURES ARE NOT CREATED EQUAL (under review) -/- A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost? “10 cents” comes to most people’s minds immediately. However, upon reflection, we can realize that “5 cents” is the correct answer. There are many reflection tests. Each has its limitations. Some reflection tests are mathematical—like the bat-and-ball problem (e.g., Frederick, 2005) and others are logical (e.g., Janis & Frick, 1943). So there are concerns that reflection tests track logical and mathematical competence rather than reflection per se. Also, some psychologists assume a priori that correct answers are reflective and lured answers are unreflective. New evidence raises additional concerns about the plausibility of these assumptions. I argue that think aloud protocols (Ericsson & Simon, 1998) and process dissociation (Jacoby, 1991) can assuage some of these concerns. -/- 4. GREAT MINDS DO NOT THINK ALIKE (in Review of Philosophy and Psychology) -/- Two large studies (N = 1299), one pre-registered, found that many correlations between reflection and philosophical beliefs among non-philosophers replicated among philosophers. For example, less reflective philosophers preferred theism to atheism and utilitarian rather than deontological responses to the trolley problem (Hannikainen & Cova, in prep.; Pennycook et al., 2016; Reynolds, Byrd, & Conway, forthcoming). However, philosophical judgments were sometimes better predicted by factors like education, gender, and personality than by reflection test performance. So although some relationships between reflection and philosophy were robust, there is more to the link between reflection and philosophy. Normative implications are also discussed—e.g., how we can infer the quality of philosophical views from their correlations with reflective or unreflective reasoning. -/- 5. WHAT WE CAN (AND CAN’T) INFER ABOUT IMPLICIT BIAS (in Synthese) -/- Contrary to some philosophers and psychologists, I argue that implicit bias is probably associative. However, I also argue that debiasing is not thereby entirely unconscious and involuntary. Indeed, strong evidence suggests that reflection can change implicitly biased behavior—e.g., conscious and deliberate counterconditioning. This has implications for the science and morality of implicit bias—e.g., evidence suggests that we can reform biases; so. intuitively, we can be responsible for biases. (shrink)

Kant’s distinction between the determining and reflecting power of judgment in the third Critique is not well understood in the literature. A mainstream view unifies these by making determination the telos of all acts of judgment (Longuenesse 1998). On this view, all reflection is primarily in the business of producing empirical concepts for cognition, and thus has what I call a determinative ideal. I argue that this view fails to take seriously the independence and autonomy of the ‘power of (...) judgment’ [Urteilskraft] as a higher cognitive faculty in its own right with its own a priori principle. Instead of seeing merely reflecting judgments as failed or incomplete acts of judgment, I argue that these are in fact paradigmatic of the activity of the power of judgment. More precisely, the reflecting power of judgment just is the power of judgment. Accordingly, reflecting judgment takes precedence over determining judgment; while the former operates according to a law that it gives itself, the latter requires another higher cognitive faculty to provide its principle. On my view, reflecting judgment should be understood as the capacity for purposive subsumption—most clearly seen in the activity of mere reflection. (shrink)

Based on the dispute between Protagoras and Socrates on the origin of ethics, one can ask the question of whether the principle of ethics is reason orfeeling/emotion, or whether ethics is grounded on reason or feeling/emotion. The development of Kant’s thoughts on ethics shows the tension between reason and feeling/emotion. In Kant’s final critical ethics, he held to a principle of “rational a priori.” On the one hand, this is presented as the rational a priori principle being the (...) binding principle of judgment. On the other hand, it is presented as the doctrine of “rational fact” as the ultimate argument of his ethics. Husserl believed that Kant’s doctrine of a rational a priori totally disregarded the a priori essential laws of feeling. Like Husserl, Scheler criticized Kant’s doctrine of a rational a priori, and therefore developed his own theory of an “emotional a priori”. Both of them focused their critiques on the grounding level of ethics. Scheler, however, did not follow Husserl all the way, but criticized him and reflected on his thoughts. At last, he revealed the primary status of a phenomenological material ethics of value. (shrink)

The problem of synthetic judgements touches on the question of whether philosophy can draw independent statements about reality in the first place. For Kant, the synthetic judgements a priori formulate the conditions of the possibility for objectively valid knowledge. Despite the principle fallibility of its statements, modern science aims for objective knowledge. This gives the topic of synthetic a priori unbroken currency. This paper aims to show that a modernized version of transcendental philosophy, if it is to be (...) feasible at all, must “bid farewell” to the concept of being “free of empiricism” or the “purity” of the a priori. Approaches to this end can already been found in Kant’s reflections on non-pure synthetic knowledge. Moreover, the a priori validity of knowledge does not exclude the possibility that it can be discovered empirically. In keeping with Kant, Fries and Nelson anticipated this separation (usually first attributed to Reichenbach) between the validity and discovery context of knowledge and pointed out that the a priori could be discovered empirically, but never proven. There are currently still good reasons why transcendental philosophical concepts are of fundamental importance for modern science, although it must not be overlooked that even within the framework of a modernized transcendental philosophy, several unsolved problems remain or are raised. For example, the irredeemability of the universal validity and necessary claims of the a priori, the problem of a clear demarcation between the phenomenal and noumenal world. Moreover, the “beautiful structure” or the Kantian system, which constituted its persuasive power, is lost. (shrink)

Hillary Putnam has famously argued that we can know that we are not brains in a vat because the hypothesis that we are is self-refuting. While Putnam's argument has generated interest primarily as a novel response to skepticism, his original use of the brain in a vat scenario was meant to illustrate a point about the "mind/world relationship." In particular, he intended it to be part of an argument against the coherence of metaphysical realism, and thus to be part of (...) a defense of his conception of truth as idealized rational acceptability. Putnam's conclusions about the scenario are, however, actually out of line with central and plausible aspects of his own account of the relationship between our minds and the world. Reflections on semantics give us no compelling reason to suppose that claims like "I am a brain in a vat" could not turn out to be true. (shrink)

What does it mean to adopt a phenomenological approach when doing philosophy of perception? And what form should such an approach take? I address these questions by first distinguishing three different ways of drawing philosophical conclusions based on phenomenological reflection: 'Humean' phenomenology, which attempts to discern the structure of perceptual experience via reflection on its surface properties; 'Kantian' phenomenology, which aims to provide a priori arguments about the structure perceptual experience must have if it is to possess (...) universally agreed upon manifest properties; and 'Husserlian' phenomenology, which aims to achieve an intuitive grasp of the essential properties of perceptual experience via attempted imaginative variation of its aspects and properties. Drawing on arguments from Merleau-Ponty, I then argue that the shortcomings of each of these approaches motivate a 'Merleau-Pontian' conception of phenomenology as 'radical reflection' - a mode of reflection on perceptual experience that simultaneously attempts to understand the origins and authority of reflection itself. The methodology for philosophy of perception that results is a thoroughly interdisciplinary one, aiming to reconcile philosophical conclusions about the necessary structures of perceptual experience with our best empirical knowledge of the bodily, psychological, cultural and historical contingencies that shape both our experiences and our reflective capacities.

I will argue that internalism about justification entails the apparently absurd conclusion that it is possible to know specific facts about the external world—for example, that there is a tree in the quad—on the basis of introspection and a priori reflection. After a brief characterization of internalism (§1), I will set out the problem (§2). I will then discuss three replies: one that denies the form of doxastic voluntarism involved in the problem (§3), one that denies that knowledge (...) of higher-order facts about justification can justify corresponding first-order beliefs (§4), and, finally, one that involves biting the bullet (§5). I will argue that each reply fails. (shrink)

Modal intuitions are the primary source of modal knowledge but also of modal error. According to the theory of modal error in this paper, modal intuitions retain their evidential force in spite of their fallibility, and erroneous modal intuitions are in principle identifiable and eliminable by subjecting our intuitions to a priori dialectic. After an inventory of standard sources of modal error, two further sources are examined in detail. The first source - namely, the failure to distinguish between metaphysical (...) possibility and various kinds of epistemic possibility - turns out to be comparatively easy to untangle and poses little threat to intuition-driven philosophical investigation. The second source is the local misunderstanding of one's concepts . This pathology may be understood on analogy with a patient who is given a clean bill of health at his annual check-up, despite his having a cold at the time of the check-up: although the patient's health is locally disrupted, his overall health is sufficiently good to enable him to overcome the cold without external intervention. Even when our understanding of certain pivotal concepts has lapsed locally, our larger body of intuitions is sufficiently reliable to allow us, without intervention, to ferret out the modal errors resulting from this lapse of understanding by means of dialectic and/or a process of a priori reflection. This source of modal error, and our capacity to overcome it, has wide-ranging implications for philosophical method - including, in particular, its promise for disarming skepticism about the classical method of intuition-driven investigation itself. Indeed, it is shown that skeptical accounts of modal error are ultimately self-defeating. (shrink)

G.A. Cohen accuses Rawls of illicitly tailoring basic principles of justice to the ‘crooked wood’ of human nature. We are naturally self-interested, for example, so justice must entice us to conform to requirements that cannot be too demanding, whereas Cohen thinks we should distinguish more clearly between pure justice and its pragmatic implementation. My suggestion is that, strictly speaking, Rawls does not rely on facts of any kind to define his constructive procedure or to argue that his principles of justice (...) would be its result – facts only come in to determine whether actual people satisfy the moral conceptions he defines and to determine whether his principles of justice can be stable for the right reasons. A distinguishing feature of normative constructivism, I claim, is that it begins with stipulated models that can include normative and descriptive elements; we then proceed to engage in a priori reflection about what these models presuppose and how they relate to one another. Rawls appeals to commonsense morality to partially define a citizen as someone who is engaged in social cooperation with others and a society as a fair system of cooperation; he then draws from these organizing ideas to characterize the original position for choosing principles of social regulation for societies and citizens so defined. Whether or not there are any actual people or societies that match Rawls’ models is a different matter, and irrelevant to the internal structure of his theory, but if the models do apply to people and societies in the real world then Rawls has given a powerful argument that his principles of justice are the most reasonable for them. Rather than watering down principles of justice to suit human nature, Rawls argues for principles of justice on a priori grounds and hopes that we can live up to the moral self-conceptions that underlie them.

Many philosophers subscribe to the view that philosophy is a priori and in the business of discovering necessary truths from the armchair. This paper sets out to empirically test this picture. If this were the case, we would expect to see this reflected in philosophical practice. In particular, we would expect philosophers to advance mostly deductive, rather than inductive, arguments. The paper shows that the percentage of philosophy articles advancing deductive arguments is higher than those advancing inductive arguments, which (...) is what we would expect from the vantage point of the armchair philosophy picture. The results also show, however, that the percentages of articles advancing deductive arguments and those advancing inductive arguments are converging over time and that the difference between inductive and deductive ratios is declining over time. This trend suggests that deductive arguments are gradually losing their status as the dominant form of argumentation in philosophy. (shrink)

One of the principle aims of the B version of Kant’s transcendental deduction is to show how it is possible that the same “I think” can accompany all of my representations, which is a transcendental condition of the possibility of judgment. Contra interpreters such as A. Brook, I show that this “I think” is an a priori (reflected) self-consciousness; contra P. Keller, I show that this a priori self-consciousness is first and foremost a consciousness of one’s personal identity (...) from a first person point of view. (shrink)

O argumento zumbi negativo parte das premissas de que p ∧ ¬q é idealmente negativamente concebível, de que o que é idealmente negativamente concebível é possível e de que o fisicalismo é incompatível com a possibilidade de p ∧ ¬q para concluir que o fisicalismo é falso. No argumento, p é a conjunção das verdades e leis físicas fundamentais e q é uma verdade fenomenal qualquer. Uma sentença φ é idealmente negativamente concebível sse um raciocinador ideal não acredita que ¬φ (...) em reflexão priori. Uma versão da tese da escrutabilidade pressuposta pelo argumento afirma que, para todo φ que sobrevém em p, o raciocinador ideal acredita que p → φ em reflexão a priori. Nesse artigo, argumento que, dado algumas interpretações relevantes da noção de probabilidade (pr(.)), o raciocinador ideal acredita verdadeiramente, para todo φ, que p → pr(φ) = x em reflexão a priori. Mas então, dependendo do valor de pr(q) e das correlações entre q e outras sentenças, o raciocinador ideal também acredita (provavelmente, verdadeiramente) que p → q em reflexão a priori. Então, para alguns qs relevantes, p ∧ ¬q não é idealmente negativamente concebível e o argumento zumbi tem uma premissa falsa. A escolha de um q adequado dependeria de informação empírica, o que faria o argumento zumbi não ser nem conclusivo, nem a priori. ENGLISH: The negative zombie argument has as premises that p∧¬q is ideally negatively conceivable, that what is ideally negatively conceivable is possible, and that Physicalism is incompatible with p∧¬q being possible and as conclusion that Physicalism is false. In the argument, p is the conjunction of the fundamental physical truths and laws and q is an arbitrary phenomenal truth. A sentence φ is ideally negatively conceivable if and only if an ideal reasoner does not believe that ¬φ on a priori reflection. The argument presupposes a version of the scrutability thesis stating that, for all φ that supervene on p, the ideal reasoner believes that p → φ on a priori reflection. In this paper, I argue that, given relevant interpretation of probabilities, the ideal reasoner believes truly, for all φ, that p → pr(φ) = x on a priori reflection. But then, depending on the value of pr(q) and the correlations between q and other sentences, the ideal reasoner also believes (probably, truly) that p → q on a priori reflection. For some relevant qs, p∧¬q is not ideally negatively conceivable and the zombie argument has a false premise. The choice of an adequate q depends on empirical information, what makes the zombie argument neither conclusive nor a priori. (shrink)

John McDowell has often emphasized the fact that the use of langauge is a rational enterprise. In this paper, I explore the sense in which this is so, arguing that our use of language depends upon our consciously knowing what our words mean. I call this a 'cognitive conception of semantic competence'. The paper also contains a close analysis of the phenomenon of implicature and some suggestions about how it should and should not be understood.

“Probably Peirce’s best-known works are the first two articles in a series of six that originally were collectively entitled Illustrations of the Logic of Science and published in Popular Science Monthly from November 1877 through August 1878. The first is entitled ‘The Fixation of Belief’ and the second is entitled ‘How to Make Our Ideas Clear.’ In the first of these papers Peirce defended, in a manner consistent with not accepting naive realism, the superiority of the scientific method over other (...) methods of overcoming doubt and ‘fixing belief.’” — Robert Burch, “Charles Sanders Peirce,” entry in the Stanford Encyclopedia of Philosophy (2021 revision) -/- “Pragmatist epistemologies often explore how we can carry out inquiries in a self-controlled and fruitful way. (Where much analytic epistemology centres around the concept of knowledge, considered as an idealised end-point of human thought, pragmatist epistemology centres around the concept of inquiry, considered as the process of knowledge-seeking and how we can improve it.) So pragmatists often provide rich accounts of the capacities or virtues that we must possess in order to inquire well, and the rules or guiding principles that we should adopt. A canonical account is Peirce’s classic early paper ‘The Fixation of Belief‘. Here Peirce states that inquiry is a struggle to replace doubt with “settled belief“, and that the only method of inquiry that can make sense of the fact that at least some of us are disturbed by inconsistent beliefs, and will subsequently reflect upon which methods of fixing belief are correct is the Method of Science, which draws on the Pragmatic Maxim described above. This contrasts with three other methods of fixing belief: i) refusing to consider evidence contrary to one’s favored beliefs (the Method of Tenacity), ii) accepting an institution’s dictates (the Method of Authority), iii) developing the most rationally coherent or elegant-seeming belief-set (the A Priori Method).“ — Catherine Legg, “Pragmatism,” entry in the Stanford Encyclopedia of Philosophy (2021 revision).

The demarcation of pseudoscience has been one of the most important philosophical tasks since the 1960s. During the 1980s, an atmosphere of defeatism started to spread among philosophers of science, some of them claimed the failure of the demarcation project. I defend that the more auspicious approach to the problem might be through the intellectual character of epistemic agents, i.e., from the point of view of vice epistemology. Unfortunately, common lists of undesirable character features are usually based on a (...) class='Hi'>priori reasoning, and therefore might be considered artificial or too vague. When we base our position on contemporary behavioural sciences, we can see that the epistemic character of believers in pseudoscience is for the most part determined by two related factors. Firstly, these epistemic agents show a higher level of cognitive laziness. By this I mean an inability or unwillingness to engage in reflective thinking and a reluctance to account for counterevidence. Secondly, they yield more easily to metacognitive overconfidence. This can be broadly understood as so-called “knowledge illusion”, the inability to recognize one’s own intellectual limits. The deficiency usually stems from a misunderstanding of the division of cognitive labour and of the agent’s role in epistemic society. I find the proposed epistemological approach to pseudoscience crucial. Only if we understand the descriptive aspects of the problem, can we think of normative solutions to it. (shrink)

Sektion Erkenntnistheorie, 29.09.2014, XXIII. Kongress der Deutschen Gesellschaft für Philosophie 2014 in Münster. -/- The problem of synthetic judgments touches upon the question whether philosophy is in fact capable of making independent truth statements. According to Kant, synthetic judgments formulate the conditions for the possibility of objectively valid knowledge a priori. As far as empirical attempts at reinterpretation of the aprioristic fall short of this ambition, Kant’s a priori goes deeper. This is because modern science strives towards objective (...) knowledge, although its statements are fundamentally fallible. The topic of synthetic a priori thus continues to be relevant. -/- This paper will show that, in order to be viable at all, a modernized version of transcendental philosophy must ‘depart from’ the concepts of “independence from empirics” and/or the “purity” of the aprioristic. Kant’s reflections on non-pure synthetic a priori knowledge already contain attempts at this. Furthermore, the aprioristic validity of knowledge does not exclude the possibility, that it can be discovered empirically. Fries and, subsequently, Nelson proceeded with this separation (initially ascribed to Reichenbach) between the contexts of validity and discovery of knowledge, pointing out that the a priori can indeed be discovered empirically, yet never be proven. -/- Currently, there are still a number of valid reasons for arguing that concepts from transcendental philosophy continue to be of fundamental importance for the modern sciences. However, it must not be neglected that, even within a modernized framework of transcendental philosophy various unsolved problems remain and/or are created (such as the unfeasibility of the aprioristic claim to general validity and necessity, the problem of drawing a clear boundary between the noumenal and phenomenal worlds). Moreover, the “beautiful structure” of the Kantian system, which constitutes much of its persuasive strength, is lost. (shrink)

Shaun Gallagher has actively looked into the possibility that psychopathologies involving “thought insertion” might supply a counterexample to the Cartesian principle according to which one can always recognize one’s own thoughts as one’s own. Animated by a general distrust of a priori demonstrations, Gallagher is convinced that pitting clinical cases against philosophical arguments is a worthwhile endeavor. There is no doubt that, if true, a falsification of the immunity to error through misidentification would entail drastic revisions in how we (...) conceive the boundary between self and other. However, I argue that (1) the idea of unearthing an exception to the Cartesian thesis is, on further reflection, not a realistic prospect and that (2) this casts doubt on the attempt to conjoin first-person phenomenology and third-person cognitive science in the service of philosophical debates.

As Thomas Uebel has recently argued, some early logical positivists saw American pragmatism as a kindred form of scientific philosophy. They associated pragmatism with William James, whom they rightly saw as allied with Ernst Mach. But what apparently blocked sympathetic positivists from pursuing commonalities with American pragmatism was the concern that James advocated some form of psychologism, a view they thought could not do justice to the a priori. This paper argues that positivists were wrong to read James as (...) offering a psychologistic account of the a priori. They had encountered James by reading Pragmatism as translated by the unabashedly psychologistic Wilhelm Jerusalem. But in more technical works, James had actually developed a form of conventionalism that anticipated the so-called “relativized” a priori positivists themselves would independently develop. While positivists arrived at conventionalism largely through reflection on the exact sciences, though, James’s account of the a priori grew from his reflections on the biological evolution of cognition, particularly in the context of his Darwin-inspired critique of Herbert Spencer.

A reflection on the merits of an a priori poeto-epistemology in relation to tacitly held assumptions about the a fortiori validity of computational logic to transcend the limits of contradiction and infinite regression and establish a valid ontology.

This chapter traces the origins of Kant's perfectionism, and so of his moral law, to the formal conception of 'nature' that emerges from his reflection on the work of Wolff and Baumgarten. The conceptual preparation for this move turns upon two hinges, both of which trace to Baumgarten's subtle modifications of Wollffian perfectionism, namely, his fuller articulation of a non-consequentialist, internal morality of actions and what I call a 'hyper-Leibnizian' account of the idea and formal structure of nature itself. (...) The fourth section shows how Kant discovers a new account of the a priori origin of this formal structure, which, when combined with his conception of unconditioned or transcendental freedom, allows him to locate an unconditioned, hence genuinely moral law, in freedom's lawlike unconditioned, intetentional imiposition of this same formal strcture, this homologia, on all its actions. In this way, the neo-Stoicism found in the earlier rationalist tradition, which bits us to 'live according to nature,' becomes in Kant the absolute duty to live according to reason's pure, a priori idea of a nature.

Abstract: This paper traces a Kantian and pragmatist line of thinking that connects the ideas of conceptual content, object cognition, and modal constraints in the form of counterfactual sustaining causal laws. It is an idea that extends from Kant’s Critique of Pure Reason through C. I. Lewis’s Mind and the World-Order to the Kantian naturalism of Wilfrid Sellars and the analytic pragmatism of Robert Brandom. Kant put forward what I characterize as a modal conception of objectivity, which he developed as (...) an extended argument stretching from the transcendental deduction through the analogies of experience to the regulative maxims of reason and reflective judgment. In related ways in Lewis and Sellars, the very idea of an object of knowledge (and of intentionality more generally) is connected with a certain lawfulness or modal constraint the necessary representation of which, they argue, is an achievement of conceptualization. While Sellars agreed with the spirit of Lewis’s famous pragmatic conception of the a priori, Sellars’s conception of meaning and conceptual content differed in crucial ways with important consequences for this issue. I argue furthermore that a certain phenomenalist temptation threatens to spoil this insight both among some of Kant’s interpreters and in Lewis’s thought. Finally, I point out that Brandom’s “Kant-Sellars thesis” provides new support for this line of thought. Although questions concerning idealism continue to raise controversies for neo-Kantians and pragmatists, the line of thought itself represents a distinctive and still promising approach to questions concerning intentionality and conceptual content.

This article aims to present one of the main themes that characterize the philosophical reflection of Jan Patočka: the appearing as such. Specifically, this papers is focused on three questions: what (was) appears? How (wie) the world appears? Which is the hidden reason (Grund) that founds appearing, but that remains hidden? The Czech philosopher reaches a conception of phenomenality in which appearance can only be conceived through an a priori structure. This conception leads to a formal transcendentalism of (...) appearing, on the basis of which it can only be thought, but not shown. The formal character of Patočka's approach, however, is a consequence of his speculative method. This speculative method, nevertheless, is problematic because on the one hand the structure of appearing is only responsible for its own laws (and not for what appears), on the other hand Patočka states that the phenomenal sphere also has a practical and vital function. The article traces the way the philosopher proceeds on this theme, which points he analyzes it discusses and which difficulties he exposes himself to. Although Patočka's reflection seems to postulate more than what he can justify (neglecting appearing as experiencing), it offers a strong hint to rethink the roots of the major phenomenological themes still remaining open.

In this article I develop an elementary system of axioms for Euclidean geometry. On one hand, the system is based on the symmetry principles which express our a priori ignorant approach to space: all places are the same to us, all directions are the same to us and all units of length we use to create geometric figures are the same to us. On the other hand, through the process of algebraic simplification, this system of axioms directly provides the (...) Weyl’s system of axioms for Euclidean geometry. The system of axioms, together with its a priori interpretation, offers new views to philosophy and pedagogy of mathematics: it supports the thesis that Euclidean geometry is a priori, it supports the thesis that in modern mathematics the Weyl’s system of axioms is dominant to the Euclid’s system because it reflects the a priori underlying symmetries, it gives a new and promising approach to learn geometry which, through the Weyl’s system of axioms, leads from the essential geometric symmetry principles of the mathematical nature directly to modern mathematics.

The negative zombie argument concludes that physicalism is false from the premises that p ∧¬q is ideally negatively conceivable and that what is ideally negatively conceivable is possible, where p is the conjunction of the fundamental physical truths and laws and q is a phenomenal truth (Chalmers 2002; 2010). A sentence φ is ideally negatively conceivable iff φ is not ruled out a priori on ideal rational reflection. In this paper, I argue that the negative zombie argument is (...) neither a priori nor conclusive. First, I argue that the premises of the argument are true only if there exists an adequate finite ideal reasoner R that believes ◊(p ∧ ¬q) on the basis of not believing p→q on a priori basis. Roughly, a finite reasoner is a reasoner with cognitive limitations (e.g. finite memory). I argue that R is finite only if R reasons nonmonotonically and only approach ideal reflection at the limit of a reasoning sequence. This would render the argument nonconclusive. Finally, I argue that, for some q, R does not believe ◊(p ∧ ¬q) on the basis of not believing p→q on a priori basis (e.g. for q =‘something is conscious’). This would render the choice of an adequate q dependent on empirical information (and the argument a posteriori). I conclude that the negative zombie argument (and, maybe, all zombie arguments) is neither a priori nor conclusive. (shrink)

The question of what ontological insights can be gained from the knowledge of physics (keyword: ontic structural realism) cannot obviously be completely separated from the view of physics as a science from an epistemological perspective. This is also visible in the debate about 'scientific realism'. This debate makes it clear, in the form of the importance of perception as a criterion for the assertion of existence in relation to the 'theoretical entities' of physics, that epistemology itself is 'ontologically loaded'. This (...) is in the form of the assumption that things in themselves (independent of cognition, in an autonomous way) exist as so-and-so determined ones. This ontological assumption is not only the basis of our (naive) conception of knowledge, but also its indispensable premise, insofar as this conception is a fundamentally passive, 'receptive' one. This is true to the full extent of metaphysics, and to a not much lesser extent of epistemology. The interpretation of knowledge in the sense of 'description' seems to be without alternative. In the philosophy of science, this view is reflected in the emphasis on 'objectivity' as the essence of science, in the belief in 'induction' as the traditional method of science, and (ex negativo) in the problem of the 'theory laden nature of observation'. To these paradigms of epistemology, however, a further aggravating factor is added, namely the criterion of 'subjective certainty' as evidence of 'real' knowledge (only meaningful on the basis of the ontological premise mentioned above). Thus, due to its 'expertise' in matters of knowledge, epistemology becomes the 'prima philosophia'. But what is even more important, the real, holistic cognitive situation is transformed into a linear cognitive relationship, with the consequence of the 'transcendence' of the objects. Now, on closer inspection, however, there is not too much in the expertise of epistemology, because it basically consists only of paradigms which, from the point of view of the holism of the real cognitive situation itself, are nothing more than relatively simplistic interpretations of this situation. However, we do not yet know what another conception of knowledge might look like (which is not surprising given the position of the phenomenon of knowledge in the hierarchy of phenomena according to their complexity). 'Certitude' as a criterion of cognition is thus excluded from the outset, and thus the linear relational model of cognition also appears as what it is, a gross distortion of the real, holistic situation of cognition. The significance of this argumentation with regard to physics is that the linear epistemological model of cognition itself is a major obstacle to an adequate epistemological understanding of physics. This is because it is fixed 'a priori' to an object-related concept of knowledge, and to 'description' as the only mode of ('real') knowledge. The acceptance of the real, holistic epistemological situation is therefore, in my opinion, the condition for an adequate understanding of physics' heuristic access to objects, its transcendental, generalizing epistemological concept, as well as its ontological relevance and dimension.

Less discussed than Hume’s skepticism about what grounds there could be for projecting empirical hypotheses is his concern with a skeptical regress that he thought threatened to extinguish any belief when we reflect that our reasoning is not perfect. The root of the problem is the fact that a reflection about our reasoning is itself a piece of reasoning. If each reflection is negative and undermining, does that not give us a diminution of our original belief to nothing? (...) It requires much attention to detail, we argue, to determine whether or not there is a skeptical problem in this neighborhood. Consider that if we subsequently doubt a doubt we had about our reasoning, that would suggest a restoration of some of the force of our original belief. We would then have instead of runaway skepticism an alternating sequence of pieces of skeptical reasoning that cancel each others’ effects on our justification in the original proposition, at least to some degree. We will argue that the outcome of the sequence of reflections Hume is imagining depends on information about a given case that is not known a priori. We conclude this from the fact that under three precise, explanatory, and viable contemporary reconstructions of what this kind of reasoning about reasoning could be like and how it has the potential to affect our original beliefs, a belief-extinguishing regress is not automatic or necessary.

ABSTRACT. May scientists rely on substantive, a priori presuppositions? Quinean naturalists say "no," but Michael Friedman and others claim that such a view cannot be squared with the actual history of science. To make his case, Friedman offers Newton's universal law of gravitation and Einstein's theory of relativity as examples of admired theories that both employ presuppositions (usually of a mathematical nature), presuppositions that do not face empirical evidence directly. In fact, Friedman claims that the use of such presuppositions (...) is a hallmark of "science as we know it." But what should we say about the special sciences, which typically do not rely on the abstruse formalisms one finds in the exact sciences? I identify a type of a priori presupposition that plays an especially striking role in the development of empirical psychology. These are ontological presuppositions about the type of object a given science purports to study. I show how such presuppositions can be both a priori and rational by investigating their role in an early flap over psychology's contested status as a natural science. The flap focused on one of the field's earliest textbooks, William James's Principles of Psychology. The work was attacked precisely for its reliance on a priori presuppositions about what James had called the "mental state," psychology's (alleged) proper object. I argue that the specific presuppositions James packed into his definition of the "mental state" were not directly responsible to empirical evidence, and so in that sense were a priori; but the presuppositions were rational in that they were crafted to help overcome philosophical objections (championed by neo-Hegelians) to the very idea that there can be a genuine science of mind. Thus, my case study gives an example of substantive, a priori presuppositions being put to use—to rational use—in the special sciences. In addition to evaluating James's use of presuppositions, my paper also offers historical reflections on two different strands of pragmatist philosophy of science. One strand, tracing back through Quine to C. S. Peirce, is more naturalistic, eschewing the use of a priori elements in science. The other strand, tracing back through Kuhn and C. I. Lewis to James, is more friendly to such presuppositions, and to that extent bears affinity with the positivist tradition Friedman occupies. (shrink)

History and the modern sciences are characterized by what is sometimes called a methodological naturalism that disregards talk of divine agency. Some religious thinkers argue that this reflects a dogmatic materialism: a non-negotiable and a priori commitment to a materialist metaphysics. In response to this charge, I make a sharp distinction between procedural requirements and metaphysical commitments. The procedural requirement of history and the sciences—that proposed explanations appeal to publicly-accessible bodies of evidence—is non-negotiable, but has no metaphysical implications. The (...) metaphysical commitment is naturalistic, but is both a posteriori and provisional, arising from the fact that for more than 400 years no proposed theistic explanation has been shown capable of meeting the procedural requirement. I argue that there is nothing to prevent religious thinkers from seeking to overturn this metaphysically naturalistic stance. But in order to do so they would need to show that their proposed theistic explanations are the best available explanations of a range of phenomena. Until this has been done, the metaphysical naturalism of history and the sciences remains defensible. (shrink)

In most accounts of realization of computational processes by physical mechanisms, it is presupposed that there is one-to-one correspondence between the causally active states of the physical process and the states of the computation. Yet such proposals either stipulate that only one model of computation is implemented, or they do not reflect upon the variety of models that could be implemented physically. In this paper, I claim that mechanistic accounts of computation should allow for a broad variation of models of (...) computation. In particular, some non-standard models should not be excluded a priori. The relationship between mathematical models of computation and mechanistically adequate models is studied in more detail.

Descartes and Boyle were the most influential proponents of strict mechanist accounts of the physical world, accounts which carried with them a distinction between primary and secondary (or sensible) qualities. For both, the distinction is a piece of natural philosophy. Nevertheless the distinction is quite differently articulated, and, especially, differently grounded in the two thinkers. For Descartes, reasoned reflection reveals to us that bodies must consist in mere extension and its modifications, and that sensible qualities as we conceive of (...) them based on sense perception can pertain only to the mind. Just how we are supposed to arrive at this realization is, this essay will argue, a deep puzzle that brings us to the basic assumptions of Descartes' metaphysics. For Boyle, by contrast, while reflection can reveal the unique explanatory status of mechanism, and, thus, the primary/secondary quality distinction, only experience can confirm its truth. Our central focus will be on Descartes, and on the question: How does he intend to remove the sensible qualities from the physical world, how does he strip them from bodies? I will try to show that Descartes has an argument that he takes to show a priori that sensible qualities cannot be attributed to the material world (as foundational qualities, or, as we conceive of them based on sense experience). The argument fails, however, leaving him with at best a partly empirical case for removing the sensible qualities, based on the purported explanatory success of his physics. (shrink)

How should we conceive of policymakers for the purposes of political analysis? In particular, if we wish to explain and predict political decisions and their consequences, if we wish to ensure that political action is as effective as it can be, how should we think of policymakers? Should we think of them as they are commonly conceived in traditional political analysis, i.e., as uniquely knowledgeable and as either altruistic (i.e., as motivated to realize goals associated with their constituents’ interests) or (...) knavish (i.e., as motivated to realize goals associated with their own personal interests), or should we treat them as possibly ignorant with respect to their political tasks? -/- It is always an open question whether policymakers possess the knowledge required to realize some policy objective. It should never be assumed a priori that policymaker knowledge is adequate to the policy tasks with which policymakers are charged. Politicians need knowledge concerning the causes of social phenomena adequate to control events sufficiently well to ensure the success of their policies. No argument has ever been offered for the standard, if only implicit, assumption that policymakers, somehow automatically, possess this knowledge. In many contexts, there is no reason to believe that policymakers possess or can acquire this knowledge. Indeed, a bit of reflection reveals how unlikely it is that and how rare the circumstances must be in which policymakers meet this condition, which political philosophers, theorists, economists, and other political thinkers have traditionally assumed as a matter of course. -/- The main purpose of the book is to encourage a conversation among scholars and students of political inquiry (in philosophy and political theory, political science, economics and political economy) concerning the best way to conceive of policymakers for the purposes of such inquiry. -/- The book defends an alternative, more realistic, method of political analysis. The book argues against the false assumption that policymakers are epistemically privileged. The book presents and defends the alternative assumption that, with respect to the knowledge required to discharge their political tasks effectively, policymakers are at least as ignorant as constituents. -/- The book further argues that whether policymakers are altruistic or knavish is, in the first instance, a function of the nature and extent of their ignorance with regard to constituent-minded policy goals. Policymakers who possess the knowledge required to be effectively altruistic are more likely to be altruistic, other things the same, than policymakers who are ignorant of the knowledge that successful altruism requires. -/- This being said, my goal is more to leave readers thinking about and inclined to debate these profound issues than to prescribe a particular methodological conclusion (even less to advocate a particular political conclusion). The book is a heuristic for spurring further conversation. It makes of readers fellow interlocutors partnered with the characters (and the author!) of the dialogue. -/- The vehicle for this analysis is a conversation between four friends, philosophy graduate students, with different interests, different levels and kinds of experience, and different political preferences. The four friends consider how politicians should be conceived for the purposes of analyzing political decision-making and its consequences. -/- In his famous Dialogues concerning Natural Religion, David Hume concluded that the assumption of an all-knowing and all-powerful God was neither necessary nor sufficient to explain natural phenomena. Dialogues concerning Natural Politics does for social science what Hume did for natural science. Both books undermine the assumption that some epistemically privileged being – God in the case of natural phenomena and God-like politicians in the case of social phenomena – must be invoked to explain relevant phenomena.

Having assigned experience this exclusive role in justification, empiricists then have a range of views concerning the character of experience, the semantics of our claims about unobservable entities, the nature of empirical confirmation, and the possibility of non-empirical warrant for some further class of claims, such as those accepted on the basis of linguistic or logical rules. Given the definitive principle of their position, empiricists can allow that we have knowledge independent of experience only where what is known is not (...) some objective fact about the world, but something about our way of conceptualizing or describing things. Some empiricists say we have knowledge of verbal equivalences or trivialities; some argue that any non-empirical tenets are not even properly called knowledge, but should be seen as notions accepted on pragmatic rather than properly epistemic grounds. What no empiricist will allow is substantive a priori knowledge: according to empiricism we have no pure rational insight into real necessities or the inner structure of nature, but must rely on the deliverances of our senses for all of our information about external reality. Some versions of empiricism argue against the very notion of real necessities or metaphysical structure behind the phenomena; other versions take a more agnostic approach, arguing that if there is a metaphysical structure behind the phenomena it is either out of our epistemic reach, or known only to the extent that it can be grasped through experience, rather than through rational reflection.

Show more ▾ There are various dichotomies in Kant’s philosophy: sensibility vs. rationality, nature vs. freedom, cognition vs. morality, noumenon vs. phenomenon, among others. There are also different ways of mediating these dichotomies, which is the systematic undertaking of Kant’s Critique of the Power of Judgment. One of the most important concepts in this work is the sublime, which exemplifies the connections between the different dichotomies; this fact means the concept’s construction is full of tension. On the one hand, as (...) a pure reflection of aesthetic judgment the sublime must be without interest or purpose, but on the other hand it is “based on the concept of reason” (KU AA:292). On the one hand, the sublime “represents merely the subjective play of the powers of the mind (imagination and reason) as harmonious” (KU AA5:258), but on the other hand, reason “exercises dominion over sensibility” and the imagination is “purposively determined in accordance with a law” of reason (KU AA5:268f). Taking into account these problems concerning the essential definition the sublime, this paper will first illustrate how the sublime embodies the a priori principle of aesthetic judgment through contrasting the judgment of the sublime with the judgment of taste in order to establish a basic logical frame for the judgment of the sublime. Second, this paper redefines the boundary between the mathematically and dynamically sublime in order to reveal both the coexistence of contemplation and movement within the sublime and the unrevealed function of reason and imagination. Finally, contrasting the sublime with moral feeling, this paper elaborates the turning-structure (from sensibility to rationality and from object-intuition to idea-exhibition) of the sublime.

I distinguish two theses regarding technological successors to current humans (posthumans): an anthropologically bounded posthumanism (ABP) and an anthropologically unbounded posthumanism (AUP). ABP proposes transcendental conditions on agency that can be held to constrain the scope for “weirdness” in the space of possible posthumans a priori. AUP, by contrast, leaves the nature of posthuman agency to be settled empirically (or technologically). Given AUP there are no “future proof” constraints on the strangeness of posthuman agents. -/- In Posthuman Life I (...) defended AUP via a critique of Donald Davidson’s work on intentionality and a “naturalistic deconstruction” of transcendental phenomenology (See also Roden 2013). In this paper I extend this critique to Robert Brandom’s account of the relationship between normativity and intentionality in Making It Explicit (MIE) and in other writings. -/- Brandom’s account understands intentionality in terms of the capacity to undertake and ascribe inferential normative commitments. It makes “first class agency” dependent on the ability to participate in discursive social practices. It implies that posthumans – insofar as they qualify as agents at all – would need to be social and discursive beings. -/- The problem with this approach, I will argue, is that it replicates a problem that Brandom discerns in Dennett’s intentional stance approach. It tells us nothing about the conditions under which a being qualifies as a potential interpreter and thus little about the conditions for meaning, understanding or agency. -/- I support this diagnosis by showing that Brandom cannot explain how a non-sapient community could bootstrap itself into sapience by setting up a basic deontic scorekeeping system without appealing (along with Davidson and Dennett) to the ways in which an idealized observer would interpret their activity. -/- This strongly suggests that interpretationist and pragmatist accounts cannot explain the semantic or the intentional without regressing to assumptions about ideal interpreters or background practices whose scope they are incapable of delimiting. It follows that Anthropologically Unbounded Posthumanism is not seriously challenged by the claim that agency and meaning are “constituted” by social practices. -/- AUP implies that we can infer no claims about the denizens of “Posthuman Possibility Space” a priori, by reflecting on the pragmatic transcendental conditions for semantic content. We thus have no reason to suppose that posthuman agents would have to be subjects of discourse or, indeed, members of communities. The scope for posthuman weirdness can be determined by recourse to engineering alone. (shrink)

In the final book of Logical Investigations from 1901, Husserl develops a theory of knowledge based on the intentional structure of consciousness. While there is some textual evidence that Husserl considered this to entail a critique of Kantian philosophy, he did not elaborate substantially on this. This paper reconstructs the covert critique of Kant’s theory of knowledge which LI contains. With respect to Kant, I discuss three core aspects of his theory of knowledge which, as Husserl’s reflections on Kant indicate, (...) Husserl was familiar with. These are the cooperation of two faculties for the justification of beliefs; the concept of a priori structures of knowledge Kant operated with; and the delivered transcendental proof of these structures. Regarding Logical Investigations, I first briefly outline the intentional structure of consciousness as presented in the fifth book and then turn to the theory of knowledge in the sixth book. I then clarify, partially on the basis of manuscripts and lecture notes, the covert critique of the three core aspects of Kant’s theory which the sixth book contains. (shrink)

Amongst the entities making up social reality, are there necessary relations whose necessity is not a mere reflection of the logical connections between corresponding concepts? We distinguish three main groups of answers to this question, associated with Hume and Adolf Reinach at opposite extremes, and with Searle who occupies a position somewhere in the middle. We first set forth Reinach’s views on what he calls ‘material necessities’ in the realm of social entities. We then attempt to show that Searle (...) has not identified a sustainable position somewhere between the Humean and the Reinachian extremes. This is because Searle’s position is threatened by circularity, and to steer clear of that danger it must incorporate at least some elements of Reinach’s essentialism. (shrink)

Kant’s dualism in anthropology and morality is said to be bridged only by means of a teleology that seems to betray the historical constitution of its subjectivity. And yet the Kantianarticulation of problems of theoretical and practical reason can be explored only insofar as they help us understand the correlated issues of the unity of reason, the relation of aesthetics and ethics in the light of the three Critiques, and the teleological conception of history. In this paper, I argue for (...) a teleological reading of the systematic architectonic so as to make sense of the concept of purposiveness as the a priori principle of judgment in its logical, aesthetic, and teleological reflection and of the unifying, a priori principles of each faculty–namely, conformity to law, final purpose, and conformity to purpose or purposiveness – respectively dealt with in the three Critiques.

This article values the importance of symbolic language through an Analog Hermeneutics and Communication Community. This philosophical itinerary starts in a collective subject called “Us” (“nosotros”) from the Latin American philosophical reflection. The symbol, such as meaningful space for semantics, shows up in a symbolic language that includes a variety of rationalities. This inclusion through symbolic language allows strengthening the “a priori” of a Communication Community that supports and ethical and historical “us”. For this purpose, an Analog Hermeneutics (...) is presented as a valid method for philosophical thinking around the symbolic language. The analogy allows considering the ambiguous and unambiguous of languages and the hermeneutics through the symbol allows us to speak and think beyond what is stated. The Analog Hermeneutics invites to recover the different meanings and to interpret the senses through the symbol in different cultures. The symbol is a new inspiration for traditional Philosophy because it recovers wisdoms, customs, images and traditions. (shrink)

By the lights of a central logical positivist thesis in modal epistemology, for every necessary truth that we know, we know it a priori and for every contingent truth that we know, we know it a posteriori. Kripke attacks on both flanks, arguing that we know necessary a posteriori truths and that we probably know contingent a priori truths. In a reflection of Kripke's confidence in his own arguments, the first of these Kripkean claims is far more (...) widely accepted than the second. Contrary to received opinion, the paper argues, the considerations Kripke adduces concerning truths purported to be necessary a posteriori do not disprove the logical positivist thesis that necessary truth and a priori truth are co-extensive.

In this paper I intend to grapple with the idea of philosophy as rigorous science from the point of view of Husserl‟s phenomenology in order to show that this idea may have an important contribution to the way in which the scientific character of sciences in general, and of human and social sciences in particular, is being conceived. As rigorous science, phenomenology emphasizes and investigates the a priori context of other sciences. In this way, it plays a vital role (...) in the development of every particular eidetic upon which any sciences rely. This eidetic (or the eidetic layer of any mature science) embraces the goal and strives to reach the objective of determining the valid sense of the fundamental notions used by the scientist in his research, without, nevertheless, stirring a radical questioning of this sense and of the ultimate validity of these notions. To define them requires passing from the usual level of inquiring of that particular science (the processes of dealing with facts and experiments) to the level (or meta-level) of a radical reflection on the sense or the meaning of the basic notions of the science in question (its own foundations). Philosophy as rigorous science connects the researcher´s assertions not only to the empirical state of affairs envisaged by his work, but, moreover and in a fundamental way, to their noematic content, to their intrinsic intentional meaning. Therefore, the idea of rigorous science elaborated in Husserl‟s phenomenology is heavy with the potential of clarifying the foundations and stakes of the research undertaken by the other sciences.

Philosophers of science often assume that logically equivalent theories are theoretically equivalent. I argue that two theses, anti-exceptionalism about logic (which says, roughly, that logic is not a priori, that it is revisable, and that it is not special or set apart from other human inquiry) and logical realism (which says, roughly, that differences in logic reflect genuine metaphysical differences in the world), make trouble for both this commitment and the closely related commitment to theories being closed under logical (...) consequence. I provide three arguments. The first two show that anti-exceptionalism about logic provides an epistemic challenge to both the closure and the equivalence claims; the third shows that logical realism provides a metaphysical challenge to both the closure and the equivalence claims. Along the way, I show that there are important methodological upshots for metaphysicians and philosophers of logic. In particular, there are lessons to be drawn about certain conceptions of naturalism as constraining the possibilities for metaphysics and the philosophy of logic. (shrink)

In this book, the words ‘science’ and ‘social science’ are used in their limited sense that refer to experience-based knowledge. This should not indicate that experience is being used in a positivistic sense. Rather, the important insights of all kinds of post-positivist views are embraced to give an extensive meaning to experience. However, the most important characteristic of experience and science that should never be excluded is its dependence on observation and observational evidence. Thus, when ‘science’ is used in combination (...) with ‘religion’, it should not be confused by religious knowledge. The latter might refer to, perhaps, a certain kind of knowledge that could be found in religious texts and might be different from other kinds of knowledge. However, when the phrase of ‘religious science’ is used, it refers to a scientific knowledge, even though because of its religious presuppositions it is called religious. And this relation between religion and science is exactly the point that is at issue in this book. On one hand, the issue of religious science raises challenges on the ground that the contemporary science has been explicitly non-religious or perhaps in some cases anti-religious. Objectivity of science is usually understood in a way that it does not permit to combine ‘science’ with ‘religion’. Thus, in the first step, the phrase of religious science is considered as nonsense. On the other hand, as far as religious people are concerned, the issue of religious science is enthusiastic. These people sometimes think that a real religion should include all scientific truths. Thus, facing the issue, they immediately verdict that there are or should be religious sciences. However, neither that strong challenge with the possibility of any religious science, nor this hot enthusiasm could be in congruence with the spirit of scientific endeavor. As far as social scientists are concerned, the possibility of religious science should not be rejected a priori. This possibility should not be necessarily considered as a threat for science, rather the plausibility of its being a chance for the development of science should also be taken into account. On the other hand, as far as the religious people are concerned, they should not necessarily consider the possibility of talking about religious sciences as a chance for spreading their religion, rather the plausibility of its being a threat for their purpose should also be considered. This is because entering of a religion into a job which is not relevant to it could be dangerous. Far from these two kinds of biases, it is attempted in this book to deal with the issue in a reflective manner. It seems that thinking about ‘religious science’ requires us to take three steps. In the first step, we need to think about the nature or characteristics of science. In the second step, we need to think about the nature or characteristics of religion. And finally, in the third step, it seem necessary to think about the combination of them. These three steps show the direction of the discussion in what follows. (shrink)

Ludwig von Mises’s methodological apriorism is frequently attributed to the broader Austrian School of economics, of which, of course, Mises was a prominent member. However, there is considerable controversy concerning the meaning of Mises’s various attempts to justify his apriorism. There are prima facie inconsistencies within and across Mises’s methodological writings that engender massive confusion in the secondary literature. This confusion is aggravated by the fact that Mises’s apriorism cannot be straightforwardly interpreted as an artifact of his historical milieu. Indeed, (...) the two prevailing families of interpretation both treat Mises’s apriorism as radically anachronistic, albeit in different senses. According to “extreme” interpretations, Mises’s apriorism reflects an epistemology several decades, if not centuries, beyond its expiration date. According to “moderate” interpretations, however, Mises’s apriorism anticipates ideas that would not appear in the epistemological literature for several decades to come. Finally, there is evidence to suggest that Mises’s actual methodological beliefs are not reflected in his writings, that Mises either obfuscated or exaggerated his methodological position, for whatever reasons, making it seem more radical than it was in fact. I conclude that we have no idea what justification Mises actually intended when he asserted the a priori nature of the fundamental propositions of economics. If this is right, then, whatever method(s) they follow, Austrian economists cannot (deliberately) follow Mises’s apriorism. (shrink)

In this issue of Studies in Transcendental Philosophy five scholars enquire about the theoretical aspects of Kant’s transcendental philosophy related to the notions of subject, self-consciousness, and self-knowledge. Andrew Brook examines Kant’s views on transcendental apperception at the end of the Critical Period, focusing on Opus Postumum which contains some of Kant’s most important reflections on the subjective dimension. As is known, the self-conscious act designated by the proposition ‘I think’ is an act of spontaneity, and this spontaneity is the (...) reason that the subject calls itself an intelligence. In his article Addison Ellis examines the theoretical and practical dimension of spontaneity, calling into question the distinction between a merely ‘relative’ spontaneity and one that is ‘absolute’. Luca Forgione points to two forms of self-consciousness introduced by Kant: inner sense, based on a sensory form of self-awareness, and transcendental apperception. Through the notion of inner sense, Kant also allows for an introspective account of self-awareness; nonetheless, Kant holds an utterly sophisticated notion of basic self-consciousness provided for by the notion of transcendental apperception. Roberto Horácio de Sá Pereira’s article presents a systematic and a historical approach, linking the contemporary debate on transcendental argument to Kant’s philosophy. It addresses both Stroud’s objection and Strawson’s perspective on transcendental argument and introduces a new reconstruction of Kant’s Refutation as successful truth-directed transcendental argument. In contrast to the contemporary movement of transhumanism and its claims that creatures like us can exist independently of our bodies, Robert Hanna develops a generalist perspective on the subjective dimension, according to which all rational human creature are synthetic a priori necessarily, essentially embodied Kantian selves. I would like to thank the authors for participating in this issue and for helping to make it really special. (shrink)

Objective: Alterations in psychomotor dimension cut across different psychiatric disorders, such as schizophrenia (SCZ) and bipolar disorder (BD). This preliminary study aimed to investigate the organization of intrinsic brain activity in the subcortical-cortical sensorimotor system in SCZ (and BD) as characterized according to psychomotor dimension. -/- Method: In this resting-state functional magnetic resonance imaging (fMRI) study, functional connectivity (FC) between thalamus and sensorimotor network (SMN), along with FC from substantia nigra (SN) and raphe nuclei (RN) to basal ganglia (BG) and (...) thalamic regions, were investigated by using an a-priori-driven and dimensional approach. This was done in two datasets: SCZ patients showing inhibited psychomotricity (n = 18) vs. controls (n = 19); SCZ patients showing excited psychomotricity (n = 20) vs. controls (n = 108). Data from a third dataset of BD in inhibited depressive or manic phases (reflecting inhibited or excited psychomotricity) were used as control. -/- Results: SCZ patients suffering from psychomotor inhibition showed decreased thalamus-SMN FC toward around-zero values paralleled by a concomitant reduction of SN-BG/thalamus FC and RN-BG/thalamus FC (as BD patients in inhibited depression). By contrast, SCZ patients suffering from psychomotor excitation exhibited increased thalamus-SMN FC toward positive values paralleled by a concomitant reduction of RN-BG/thalamus FC (as BD patients in mania). -/- Conclusions: These findings suggest that patients exhibiting low or high levels of psychomotor activity show distinct patterns of thalamus-SMN coupling, which could be traced to specific deficit in SN- or RN-related connectivity. Notably, this was independent from the diagnosis of SCZ or BD, supporting an RDoC-like dimensional approach to psychomotricity. (shrink)

In the Critique of the Power of Judgment, Kant introduces the notion of the reflective judgment and the a priori principle of purposiveness or systematicity of nature. He claims that the ability to judge objects by means of this principle underlies empirical concept acquisition and it is therefore necessary for cognition in general. In addition, he suggests that there is a connection between this principle and judgments of taste. Kant’s account of this connection has been criticized by several commentators (...) for the reason that it leads to the ‘everythingisbeautiful’ problem. In this paper I argue, contrary to these objections, that both finding an object beautiful and acquiring the concept represent the satisfaction of the same principle of nature’s purposiveness, which refers to the same cognitive need we have, that is, to systematize experience. I avoid the ‘everything is beautiful’ problem by arguing that aesthetic reflection refers to the synthesis of object’s individual and distinctive properties, while logical reflection refers to the synthesis of object’s general properties that it shares with other objects of its kind. Because aesthetic purposiveness is different from logical purposiveness, this allows for the possibility that we can have an object of cognition, without finding this object beautiful. (shrink)
