While the idea that philosophy requires self-transformation is historically pervasive, it exerts considerable influence on the post-Kantians who first aim to systematize Kant’s idealism by grounding it on a first principle. In the 1790s, Fichte and Schelling offer competing accounts of the self-transformation that they regard as essential to positing a first principle. Their accounts raise two central questions. First, what makes this kind of self-transformation possible? Second, are there different possible expressions of philosophical self-transformation? In what follows, I will (...) articulate the Fichtean and Schellingian answers to these central questions. For Fichte, the one who summons me to posit a first principle makes possible my philosophical self-transformation, although the latter has an exclusively idealist expression in that I can only genuinely posit the I as first principle, which is to say that philosophical self-transformation depends on mutual recognition and vindicates precisely one philosophical system (Section 1). For Schelling, a brute act of will makes possible my philosophical self-transformation, although the latter has either an idealist or a realist expression in that I can genuinely posit either the I or the not-I as first principle, which is to say that philosophical self-transformation does not depend on mutual recognition and vindicates one of two possible philosophical systems (Section 2). Thus, whereas Fichtean self-transformation is recognitive and non-pluralistic, Schellingian self-transformation is pluralistic and non-recognitive. I conclude with a discussion of how Jacobi poses a challenge to Fichte’s and Schelling’s answers to the two central questions (Section 3). (shrink)

In a series of papers Ladyman and Presnell raise an interesting challenge of providing a pre-mathematical justification for homotopy type theory. In response, they propose what they claim to be an informal semantics for homotopy type theory where types and terms are regarded as mathematical concepts. The aim of this paper is to raise some issues which need to be resolved for the successful development of their types-as-concepts interpretation.

In the Freedom essay, Schelling charges that (1) idealism fails to grasp human freedom’s distinctiveness and that (2) this failure undermines idealism's attempt to refute pantheism, as exemplified by Spinoza. This raises two questions, which I will answer in turn: what, for Schelling, is distinctive of human freedom; and how does the idealists’ failure to grasp it render them unable to refute pantheism? To answer these questions, I will reconstruct Schelling’s argument that freedom has the distinctness of being the unconditioned (...) condition of the world’s intelligibility. My reconstruction will illustrate how Schelling’s notion of freedom as primal will grounds the alleged primacy of practical reason as Kant and Fichte conceive it. I will then consider three objections to Schelling’s argument. Throughout, I will develop the Schellingian idea that freedom is enacted in an unprethinkable decision that cannot be anticipated by any law or principle. (shrink)

Kant’s critique/doctrine distinction tracks the difference between a canon for the understanding’s proper use and an organon for its dialectical misuse. The latter reflects the dogmatic use of reason to attain a doctrine of knowledge with no antecedent critique. In the 1790s, Fichte collapses Kant’s distinction and redefines dogmatism. He argues that deriving a canon is essentially dialectical and thus yields an organon: critical idealism is properly a doctrine of science or Wissenschaftslehre. Criticism is furthermore said to refute dogmatism, by (...) which Fichte means Spinozism. Schelling repudiates Fichte’s position in his Philosophical Letters by reviving Kant’s distinction. First, ‘critique’ for Schelling names a canon that is valid for all systems—including Spinozism—and thus favours none—not even the Wissenschaftslehre. Second, Schelling coins ‘dogmaticism’ to refer to what Kant calls ‘dogmatism’: reason’s uncritical claim to doctrine. Hence, he says all systems—even Fichte’s—are susceptible to the ‘enthusiasm’ of mistaking themselves for doctrines or ‘objects of knowledge’, instead of subjectively valid ‘objects of freedom’. I reconstruct Schelling’s argument for reviving Kant’s distinction, while noting two consequences for German idealism. First, if criticism favours no system, a system’s origin cannot be an act of knowledge, e.g., intellectual intuition, but only an act of endorsement. Second, if dogmaticism entails enthusiasm, a system’s goal cannot be absolute knowledge, but only infinite striving. Hence, by retrieving Schelling’s notion of dogmaticism, we can both gain a better understanding of the Letters and register the impact of a core Kantian distinction on the German idealist project.

Fichte argues that the conclusion of Kant’s transcendental deduction of the categories is correct yet lacks a crucial premise, given Kant’s admission that the metaphysical deduction locates an arbitrary origin for the categories. Fichte provides the missing premise by employing a new method: a genetic deduction of the categories from a first principle. Since Fichte claims to articulate the same view as Kant in a different, it is crucial to grasp genetic deduction in relation to the sorts of deduction that (...) Kant offers. I propose to interpret genetic deduction as the simultaneous fulfillment of two tasks: answering the question quid facti by deriving the categories from the I and answering the question quid juris by establishing our entitlement to the categories as conditions of experience. While the second task represents Fichte’s agreement with Kant’s transcendental deduction, the first reflects his correction of Kant’s metaphysical deduction. (shrink)

Fichte assigns ‘intellectual intuition’ a new meaning after Kant. But in 1799, his doctrine of intellectual intuition is publicly deemed indefensible by Kant and nihilistic by Jacobi. I propose to defend Fichte’s doctrine against these charges, leaving aside whether it captures what he calls the ‘spirit’ of transcendental idealism. I do so by articulating three problems that motivate Fichte’s redirection of intellectual intuition from being to acting: (1) the regress problem, which states that reflecting on empirical facts of consciousness leads (...) only to further facts and so cannot yield a first principle; (2) the rhapsody problem, which states that the categories form a haphazard set and so lack necessity unless they derive from a first principle; and (3) the nihilism problem, which states that a first principle cannot lie outside our cognition of it, lest it be the cause of our cognition and, being first, the cause of all our actions, reducing us to machines. Crucially, Fichte’s three motivating problems are in fact aspects of a single problem. Leaving any aspect unsolved spoils putative solutions to the other two. Consequently, Fichte requires a single unified solution to all three, which his doctrine of intellectual intuition provides. (shrink)

I argue against the interpretation of propositions as intentions and proof-objects as fulfillments proposed by Heyting and defended by Tieszen and van Atten. The idea is already a frequent target of criticisms regarding the incompatibility of Brouwer’s and Husserl’s positions, mainly by Rosado Haddock and Hill. I raise a stronger objection in this paper. My claim is that even if we grant that the incompatibility can be properly dealt with, as van Atten believes it can, two fundamental issues indicate that (...) the interpretation is unsustainable regardless: (1) it is hard to determine, without appealing to propositional intentions on pain of circularity, what intention a proof-object should be understood as a fulfillment of; (2) due to a difficult fulfillment dilemma, it is unclear, at best, what the object of an intention corresponding to a proposition is.

This paper argues that McDowell wrongly assumes that “terror”, Cavell’s reaction to the radical contingency of our shared modes of knowing or our “attunement”, expresses a skepticism that is antinomically bound to an equally unacceptable dogmatism because Cavell rather regards terror as a mood that reveals the “truth of skepticism”, namely, that there is no conclusive evidence for necessary attunement on pain of a category error, and that a precedent for McDowell’s misunderstanding is Hegel’s argument for necessary attunement in a (...) system of knowing, whose refutation Schelling holds it is the “merit of skepticism” to provide.

My first aim in this paper is to use time diagrams in the style of Brentano to analyze constructions in Brouwer's separable mathematics more precisely. I argue that constructions must involve not only pairing and projecting as basic operations guaranteed by the intuition of twoity, as sometimes assumed in the literature, but also a recalling operation. My second aim is to argue that Brouwer's views on the intuition of twoity and arithmetic lead to an ontological explosion. Redeveloping the constructions of (...) natural numbers and systems sketched in an appendix to Brouwer's Cambridge lectures, I observe that the only plausible way he can make some elementary arithmetic in his separable mathematics is by allowing for the same canonical number to be determined by multiple separable entities, resulting in an overabundant mathematical ontology.

A precursor to the hard problem of consciousness confronts nihilism. Like physicalism, nihilism collides with the first-personal fact of what perception and action are like. Unless this problem is solved, nature’s inclusion of conscious experience will remain, as Chalmers warns the physicalist, an “unanswered question” and, as Jacobi chides the nihilist, “completely inexplicable". One advantage of Kant’s Copernican turn is to dismiss the question that imposes this hard problem. We need not ask how nature is accompanied by the first-person standpoint (...) because “I think” is an apperceptive form of thinking that must be able to accompany any cognition of nature. Kant’s formal conception of apperception worries Fichte in his Nova Methodo lectures. This conception arguably cannot exhaust the ground of experience, for it does not show why we posit objects “at all". For Fichte, it is our agency that first opens a world of objects, viz., as subjects, means, ends, and obstacles. In what follows, I argue that, for Fichte, the I poses no hard problem because it collides exclusively with nihilistic views like Spinozism, which are refuted by a properly transcendental idealist conception of apperception, according to which the first-person standpoint is the absolute ground of our experience of nature. If transcendental idealism refutes nihilism, nature is no more explicable than that there is something it is like for me to perceive and act. In Section 1, I show why Kantian apperception is necessary for possible experience. In Section 2, I reconstruct Fichte’s argument that a modified conception of apperception refutes guises of nihilism, thereby solving the hard problem of consciousness. In Section 3, I suggest that transcendental idealism undermines Chalmers’ proposed solution to and Dennett’s dismissal of this problem. (shrink)

In the Vocation of Man, Fichte makes the striking claim that life is eternal, rational, our true being, and the final cause of nature in general and of death in particular. How can we make sense of this claim? I argue that the public lectures that compose the Vocation are a popular expression of Fichte’s pre-existing commitment to what I call immortalism, the view that life is the unconditioned condition of intelligibility. Casting the I as an absolutely self-active or living (...) power enables his philosophical account of both the intelligibility of objects and of what it means to die. This explains his characterization of the Wissenschaftslehre as a system in which ‘all is act, movement, and life’. In Sect. 1, I explain the context of Jacobi’s use of ‘caput mortuum’ as a term for the thing in itself. In Sects. 2 and 3, I reconstruct two immortalist arguments from Fichte’s Jena period. The first is that the I’s self-activity rules out the existence of the thing in itself and thereby vanquishes ‘death’s head’. The second is that, insofar as the I charges us with the moral perfection of nature, it is the final cause of our entire life, including its end. This is to say that the I puts our every moment into question, even our last. In Sect. 4, I use these immortalist arguments to interpret the striking claim from the Vocation. (shrink)

O pensamento de Leibniz foi, sem dúvida, essencial para o desenvolvimento das linhas fundamentais da filosofia crítico-transcendental de Kant. A interlocução entre Kant e Leibniz é evidente no decorrer do pensamento kantiano, seja diretamente, nos diversos momentos em que Kant busca um enfrentamento explícito com seu predecessor, seja indiretamente, quando Kant discute com os autores da escolástica alemã que são considerados discípulos de Leibniz Pretendo observar, em particular, que uma das discussões pouco noticiadas, mas de grande relevância para o desenvolvimento (...) do pensamento kantiano, é aquela em relação ao problema da teodiceia. Com isso em foco, meu objetivo nesse capítulo é o de tentar mostrar alguns aspectos do diálogo de Kant com a teodiceia de Leibniz. Primeiro, apresentarei alguns aspectos da teodiceia de Leibniz. Depois, mostrarei o tratamento que Kant dispensa ao problema da teodiceia em alguns de seus escritos iniciais. Por fim, apresentarei o seu tratamento no período crítico, da maneira como se expõe em um artigo de 1791 intitulado Sobre o Fracasso de todas as Tentativas Filosóficas na Teodiceia. De modo complementar, ao abordar o problema no período crítico, farei algumas remissões às três Críticas, às Lições sobre a Doutrina Filosófica da Religião de 1783/84, às Lições de Ética e à Religião nos Limites da Simples Razão de 1793.

Throughout his career, Schelling assigns knowledge of the absolute first principle of philosophy to intellectual intuition. Schelling's doctrine of intellectual intuition raises two important questions for interpreters. First, given that his doctrine undergoes several changes before and after his identity philosophy, to what extent can he be said to “hold onto” the same “sense” of it by the 1830s, as he claims? Second, given that his doctrine of intellectual intuition restricts absolute idealism to what he calls a “science of reason”, (...) which he says cannot prove the absolute’s existence, what other doctrine does he require in order to prove this? I will answer these questions by tracing the shifts in Schelling’s doctrine of intellectual intuition from the 1790s to the 1830s and drawing out its evolving methodological role within his science of intelligibility.

Abstract: The standard picture of rationality requires that the agent acts so as to realize her most preferred alternative in the light of her own desires and beliefs. However, there are circumstances where such an agent can predict that she will act against her preferences. The story of Ulysses and the Sirens is the paradigmatic example of such cases. In those circumstances the orthodoxy requires the agent to be ‘sophisticated’. That is to say, she should take into account her expected (...) future choices and prevent her future self to act in certain ways. She should ‘bind’ herself to a certain course of action. This is a form of causal commitment. It is generally recognized that this form of self-commitment is the only one that is available to a rational agent. Rational commitment, where the agent gives herself a reason to act in a certain way rather than making herself act in that way, is considered not feasible. In this paper, I question this verdict. I sketch the broad outlines of a model of rational commitment, which takes as its starting point Michael Bratman’s ‘planning theory’ of intention. There are two important objections against this theory (one by John Broome and one by the Dutch philosopher Govert den Hartogh.) Both criticisms claim that such a theory is a form of ‘bootstrapping’ reasons for action into existence. In the remainder of the paper, I will defend the theory against these objections. This way, I hope to establish that defending the feasibility of rational commitment is not an obvious mistake. (shrink)

The aim of the paper is to argue that all—or almost all—logical rules have exceptions. In particular, it is argued that this is a moral that we should draw from the semantic paradoxes. The idea that we should respond to the paradoxes by revising logic in some way is familiar. But previous proposals advocate the replacement of classical logic with some alternative logic. That is, some alternative system of rules, where it is taken for granted that these hold without exception. (...) The present proposal is quite different. According to this, there is no such alternative logic. Rather, classical logic retains the status of the ‘one true logic’, but this status must be reconceived so as to be compatible with (almost) all of its rules admitting of exceptions. This would seem to have significant repercussions for a range of widely held views about logic: e.g. that it is a priori, or that it is necessary. Indeed, if the arguments of the paper succeed, then such views must be given up. (shrink)

The concept of facticity denotes conditions of experience whose necessity is not logical yet whose contingency is not empirical. Although often associated with Heidegger, Fichte coins ‘facticity’ in his Berlin period to refer to the conclusion of Kant’s metaphysical deduction of the categories, which he argues leaves it a contingent matter that we have the conditions of experience that we do. Such rhapsodic or factical conditions, he argues, must follow necessarily, independent of empirical givenness, from the I through a process (...) of ‘genesis.’ I reconstruct Fichte’s argument by tracing the origin of his neologism, presenting his Jena critique of Kant’s rhapsodic appeal to the forms of judgment, and illustrating the Jena period’s continuity with the Berlin period’s genetic method, while noting a methodological shift whereby Fichte directs his critique against his own doctrine of intellectual intuition in order to eliminate its ‘factical terms.’.

This chapter intervenes in recent debates in Kant scholarship about the possibility of a general logical alien. Such an alien is a thinker whose laws of thinking violate ours. She is third-personal as she is radically unlike us. Proponents of the constitutive reading of Kant’s conception of general logic accordingly suggest that Kant rules out the possibility of such an alien as unthinkable. I add to this an often-overlooked element in Kant’s thinking: there is reason to think that he grants—and (...) in fact presupposes—the possibility of a transcendental logical alien. Such an alien is a knower whose laws of experience purport to violate ours. She is first-personal as she is radically like us. In other words, she is us, insofar as we are alienated from ourselves and our experience. I go on to draw an analogy between her, a dogmatist, and another transcendental alien, an evil agent. Just as a dogmatist is alienated from her (our) experiential laws, an evil agent is alienated from her (our) moral law. These forms of theoretical and practical self-conceit require self-knowledge in the form of a critique of speculative or practical reason. In bringing this point out, I aim to shift from the question of whether logical laws constitute our thinking to the question of whether grasping our experiential and moral laws as our laws constitutes our reason.

This paper argues that we should solve paradoxes for propositions (such as the Russell–Myhill paradox) in essentially the same way that we solve Russellian paradoxes for sets. That is, the standard, iterative approach to sets is extended to include properties, and then the resulting hierarchy of sets and properties is used to construct propositions. Propositions on this account are structured in the sense of mirroring the sentences that express them, and they would seem to serve the needs of philosophers of (...) language and metaphysicians who rely on such propositions. The resulting account has limitations, comparable to those faced by the iterative approach to sets, but it is argued to be in important ways preferable to others that have been proposed. (shrink)

On the classical understanding, an agent is fully excused for an action if and only if performing this action was a case of faultless wrongdoing. A major motivation for this view is the apparent existence of paradigmatic types of excusing considerations, affecting fault but not wrongness. I show that three such considerations, ignorance, duress and compulsion, can be shown to have direct bearing on the permissibility of actions. The appeal to distinctly identifiable excusing considerations thus does not stand up to (...) closer scrutiny, undermining the classical view and giving us reason to seek alternative ways of drawing the justification/excuse distinction.

The aim of this paper is to present a constructive solution to Frege's puzzle (largely limited to the mathematical context) based on type theory. Two ways in which an equality statement may be said to have cognitive significance are distinguished. One concerns the mode of presentation of the equality, the other its mode of proof. Frege's distinction between sense and reference, which emphasizes the former aspect, cannot adequately explain the cognitive significance of equality statements unless a clear identity criterion for (...) senses is provided. It is argued that providing a solution based on proofs is more satisfactory from the standpoint of constructive semantics. (shrink)

A necessarily true sentence is 'brute' if it does not rigidly refer to anything and if it cannot be reduced to a logical truth. The question of whether there are brute necessities is an extremely natural one. Cian Dorr has recently argued for far-reaching metaphysical claims on the basis of the principle that there are no brute necessities: he initially argued that there are no non-symmetric relations, and later that there are no abstract objects at all. I argue that there (...) are nominalistically acceptable brute necessities, and that Dorr's arguments thus fail. My argument is an application of Gödel's first incompleteness theorem. (shrink)

It is a well-worn platitude that knowledge excludes luck. According to anti-luck virtue epistemology, making good on the anti-luck platitude requires an explicit anti-luck condition along the lines of safety: S knows that p only if S’s true belief that p could not have easily been mistaken. This paper offers an independent, virtue epistemological argument against the claim that safety is a necessary condition on knowledge, one that adequately captures the anti-luck platitude. The argument proceeds by way of analogy. I (...) focus on two paradigmatic kinds of normative achievements that also exclude luck: (i) – having a doxastically justified belief, and (ii) – performing a morally worthy action. I then show that while (i) and (ii) exclude luck, they are nevertheless susceptible to what I call ‘modal luck’. I then move on to show that knowledge, or at least some instance of knowledge, is a normative achievement, which I claim provides strong reasons to expect that knowledge is also susceptible to modal luck. Since safety entails that knowledge is incompatible with modal luck, the argument provides strong reasons to reject safety as a necessary condition on knowledge. (shrink)

Most of us spend a significant portion of our lives learning, practising, and performing a wide range of skills. Many of us also have a great amount of control over which skills we learn and develop. From choices as significant as career pursuits to those as minor as how we spend our weeknight leisure time, we exercise a great amount of agency over what we know and what we can do. In this paper we argue, using a framework first developed (...) by Carbonell (2013) that in many real-world circumstances we have moral obligations to develop some skills rather than others.

Metaphysically possible worlds have many uses. Epistemically possible worlds promise to be similarly useful, especially in connection with propositions and propositional attitudes. However, I argue that there is a serious threat to the natural accounts of epistemically possible worlds, from a version of Russell’s paradox. I contrast this threat with David Kaplan’s problem for metaphysical possible world semantics: Kaplan’s problem can be straightforwardly rebutted, the problems I raise cannot. I argue that although there may be coherent accounts of epistemically possible (...) worlds with fruitful applications, any such an account must fundamentally compromise the basic idea behind epistemic possibility.

‘Facticity’ is a concept that classical phenomenologists like Heidegger use to denote the radically contingent or underivably brute conditions of intelligibility. Yet Fichte coins the term, to which he gives the opposing use of denoting unacceptably brute conditions of intelligibility. For him, radical contingency is a problem to be solved by deriving such conditions from reason. Heidegger rejects Fichte's recoil from facticity with his hermeneutics of facticity, supplanting Fichte's metaphor of our always being in reason's hand with the metaphor of (...) our always having been thrown. How does Heidegger inherit and diametrically repurpose Fichte's neologism? Whence the reversed meaning of ‘facticity’ in post-Kantian thought? The answer is Lask's doctoral thesis, which exerts an acknowledged impact on Heidegger's habilitation thesis. Lask interprets ‘facticity’ as Fichte's term for the individuality problem, that is, the resistance of the material particularity of individuals to explanation by the categories genetically deduced from reason. On his interpretation, ‘facticity’ denotes radical contingency in the guise of haecceity, that is, the brute uniqueness of individuals. Lask credits Fichte with registering the problem of individuality, which highlights the world's irreducibly precategorial character. But how is ‘facticity’ transmitted from Lask to Heidegger, given their opposing interpretations of how Fichte understands its meaning? I argue that (1) Lask misreads Fichte as a proponent of facticity, that is, one whose accommodation of radical contingency deflates the Wissenschaftslehre's systematic ambitions, and (2) Lask's misreading, without deceiving Heidegger regarding the sincerity of Fichte's ambitions, encourages Heidegger's own hermeneutics of facticity.

In this paper, I revisit Frege's theory of sense and reference in the constructive setting of the meaning explanations of type theory, extending and sharpening a program–value analysis of sense and reference proposed by Martin-Löf building on previous work of Dummett. I propose a computational identity criterion for senses and argue that it validates what I see as the most plausible interpretation of Frege's equipollence principle for both sentences and singular terms. Before doing so, I examine Frege's implementation of his (...) theory of sense and reference in the logical framework of Grundgesetze, his doctrine of truth values, and views on sameness of sense as equipollence of assertions.

A puzzle arises when we consider that, for Kant, the categories are 'original acquisitions' of our understanding to which we must nevertheless prove our entitlement via 'deduction', on pain of dogmatism. I resolve this puzzle by articulating skepticism’s role in the transcendental deduction, drawing on Kant’s construal of the skeptical 'question quid juris' in the juridical terms of entitlement to property. I then situate skepticism’s transformative potential within what Kant regards as reason’s 'maturation' from dogmatism toward self-knowledge. Finally, I contrast (...) Hegel’s account of spirit’s progress toward 'absolute knowledge', which shifts both the mode of skepticism and the prospect of maturation. (shrink)

Ontological pluralism is the view that there are different ways to exist. It is a position with deep roots in the history of philosophy, and in which there has been a recent resurgence of interest. In contemporary presentations, it is stated in terms of fundamental languages: as the view that such languages contain more than one quantifier. For example, one ranging over abstract objects, and another over concrete ones. A natural worry, however, is that the languages proposed by the pluralist (...) are mere notational variants of those proposed by the monist, in which case the debate between the two positions would not seem to be substantive. Jason Turner has given an ingenious response to this worry, in terms of a principle that he calls ‘logical realism’. This paper offers a counter-response on behalf of the ‘notationalist’. I argue that, properly applied, the principle of logical realism is no threat to the claim that the languages in question are notational variants. Indeed, there seems to be every reason to think that they are. (shrink)

It is commonly assumed that blameworthiness is epistemically constrained. If one lacks sufficient epistemic access to the fact that some action harms another, then one cannot be blamed for harming. Acceptance of an epistemic condition for blameworthiness can give rise to a worry, however: could agents ever successfully evade blameworthiness by deliberately stunting their epistemic position? I discuss a particularly worrisome version of such epistemic shirking, in which agents pre-emptively seek to avoid access to potentially morally relevant facts. As Roy (...) Sorensen and Jan Willem Wieland have argued, we seem to be faced with a potentially troubling regress when trying to explain what goes wrong in such situations. I argue that the solution to this so-called Shirker Problem is not to be found in complicated and demanding anti-shirking-principles with universal scope and potentially self-reflexive content. Instead, careful consideration of the necessary motivational make-up of genuine shirkers reveals their ignorance to lack the necessary depth to be exculpatory. Since shirkers by definition react to the possibility of the revelation of morally relevant facts with acts of epistemic self-limitation, they necessarily prove guilty of a form of culpable moral recklessness. Epistemic shirking thus does not pose a worrisome problem for ethical theory. (shrink)

In this paper, my aim is to reconstruct, through the material presented in the handschrifter Nachlaß, Kant`s criticism to Hutcheson and to the doctrine of moral feeling in the 1770s in the so called silent decade. As we can note, this criticism generally is addressed to the fact that the doctrine of moral feeling is lacking an objective ground on which can be established a categorical conception of ethics. Moreover, I argue that in this context Kant already demonstrates, from his (...) critical position in the Reflexionen and Vorlesungen, the general lines of his mature conception on moral feeling as something strictly linked to our awareness of the law. (shrink)

During his Jena period, Fichte endorses a curious dictum: ‘the kind of philosophy one chooses depends on the kind of person one is’. How can Fichte’s dictum support a vindication of German idealism over Spinozism, which he also calls ‘dogmatism’? I will show that the answer to this seemingly straightforward question reveals a rather complex series of metametaphysical objections that shape the development of the entire German idealist tradition. Ultimately, as I will suggest, the series of metametaphysical questions that shape (...) the German idealist tradition must culminate in the question of how to understand the relation between philosophy and its presuppositions. I will conclude by briefly considering a hermeneutical response to this question. (shrink)

Scholars agree that Schelling’s critique of Hegel consists in charging reason with an inability to account for its own possibility. This is not an attack on reason’s project of constructing a logical system, but rather on the pretense of doing so with complete justification and so without presuppositions, as if it were obvious why there is a logical system or why there is anything meaningful at all. Scholars accordingly cite the question ‘why is there something rather than nothing’ as emblematic (...) of Schelling’s critique and the source of his claim against Hegel that reason is bounded by something other than itself. But what sort of claim is this? For what sort of argument could it be the conclusion? On these questions, the literature is lacking. I propose that the question ‘why something’ motivates Schelling to give a transcendental argument to the effect that past and future are a priori conditions of the possibility of reason. As I reconstruct it from the Weltalter, this argument construes the past as the pre-rational decision to construct a logical system, while the future represents the purpose that guides the construction of the same. Schelling’s claim against Hegel that reason is bounded by something other is thus the discovery of inescapable presuppositions that condition the possibility of reason as such. (shrink)

Our understanding of Schelling’s internal critique of German idealism, including his late attack on Hegel, is incomplete unless we trace it to the early “Philosophical Letters on Dogmatism and Criticism,” which initiate his engagement with the problem of systematicity—that judgment makes deriving a system of a priori conditions from a first principle necessary, while this capacity’s finitude makes this impossible. Schelling aims to demonstrate this problem’s intractability. My conceptual aim is to reconstruct this from the “Letters,” which reject Fichte’s claim (...) that the Wissenschaftslehre is an unrivalled system. I read Schelling as charging Fichte with misrepresenting a system’s livability or commensurability with our finitude. My historical aim is to provide a framework for understanding Schelling’s Freiheitsschrift, which argues that a system’s liveability depends on its incompleteness or limitation by our finitude. On my reading, Schelling is early and continually committed to systematicity within the bounds of human finitude. (shrink)

Meillassoux defines “correlationism” as the view that we can only access the mutual dependence of thought and being—specifically, subjectivity and objectivity—which he attributes to Heidegger. This attribution is inapt. It is only by accessing being—via existential analysis—that we can properly distinguish beings like subjects and objects. I propose that Meillassoux’s misattribution ignores the ontological difference that drives Heidegger’s project. First, I demonstrate the inadequacy of Meillassoux’s account of correlationism as a criticism of Heidegger and dispense with an objection. Second, I (...) argue that Meillassoux’s neglect of the ontological difference stems from a question-begging appeal to transcendental realism, which is at odds with Heidegger’s twin claims for a variety of transcendental idealism in Being and Time. Third, I offer a reflection on three general marks of transcendental idealism. (shrink)

This paper aims to answer the question of whether or not Frege's solution limited to value-ranges and truth-values proposed to resolve the "problem of indeterminacy of reference" in section 10 of Grundgesetze is a violation of his principle of complete determination, which states that a predicate must be defined to apply for all objects in general. Closely related to this doubt is the common allegation that Frege was unable to solve a persistent version of the Caesar problem for value-ranges. It (...) is argued that, in Frege’s standards of reducing arithmetic to logic, his solution to the indeterminacy does not give rise to any sort of Caesar problem in the book. (shrink)

In his article Banicki proposes a universal model for all forms of philosophical therapy. He is guided by works of Martha Nussbaum, who in turn makes recourse to Aristotle. As compared to Nussbaum’s approach, Banicki’s model is more medical and less based on ethical argument. He mentions Foucault’s vision to apply the same theoretical analysis for the ailments of the body and the soul and to use the same kind of approach in treating and curing them. In his interpretation of (...) philosophical therapy, there are, however, some controversial issues, to which we would like to call attention: -/- Is restoring health by a philosophical method of treatment – health understood as a person’s ability to reach his/her vital goals – a convincing explication of philosophical therapy in general? In order to answer this question, it may be useful to look at Plato. It is not only Platonism (and especially Neo-platonism since Plotinus) that questions the idea that therapy is necessarily connected with „vital goals“. Buddhist and Gnostic philosophies are questioning „the vital“ in general. The immense effort in the history of philosophy to liberate the mind from the body casts doubt on the project to explain philosophical therapy solely in analogy to medical therapy. -/- According to Banicki a therapeutic philosophy has to identify the diseases it attempts at curing. There are, however, reasons for associating the term therapy with suffering/risk rather than disease. If a therapy aims at reducing the fear of death, as for example many classical philosophical therapies do, then there is no disease to be cured. A model based on chances and risks also has the advantage that the Buddhist and Stoic reinterpretation of desires/emotions as “diseases” can be dropped in contemporary philosophical therapy. -/- Banicki mentions the comparison of therapies as one of the primary goals of modelling. Methods should be verified by a statistical correlation between method and therapeutic success and/or by a theory which justifies the method. Some forms of therapies, however, avoid theory-specific terms and concepts in favor of an unprejudiced interpretation of the patient’s statements. Others share the (Nietzschean) aspiration to explore and change measures of value. If the therapeutic process is seen as a unique phenomenon, then there can be no theory and no statistics with co-occurrences. -/- According to Banicki philosophical therapy has to describe techniques which qualify as genuinely philosophical. Techniques like maieutics and hermeneutics, however, are antique philosophical “inventions”, which were later adopted by psychotherapy. If meditation is accepted as a therapeutic tool – as it was in ancient times – then there is not only a methodical but also an emotional relation to religion. If finally, the Socratic search for a good life is seen as one of the characteristics of philosophical therapy, then delimitation even turns into a criterion for non-philosophical therapies. The search for a good life requires an interdisciplinary approach. -/- For the concretization of the formal structure, we suggest a typology of therapies, which is based on chances and risks. Such a typology has the advantage, that it can model conflicting (and even opposing) forms of therapies. The variety of therapeutic goals and methods is a consequence of the historical development towards conceptual freedom. (shrink)

If a problem is the collision between a system and a fact, Spinozism and German idealism’s greatest problem is the corpse. Life’s end is problematic for the denial of death’s qualitative difference from life and the affirmation of nature’s infinite purposiveness. In particular, German idealism exemplifies immortalism – the view that life is the unconditioned condition of all experience, including death. If idealism cannot explain the corpse, death is not grounded on life, which invites mortalism – the view that death (...) is the unconditioned condition of experience. In “Philosophical Letters,” Schelling critiques idealism, arguing that death symbolizes the regulative ideal of a philosophical system’s derivation, our striving for which unifies our rational activity. I interpret Schelling’s critique as explaining how death puts philosophy into question, an idea he develops in the Freedom essay and Berlin lectures. Death is not a problem to be solved by a system, but represents philosophy’s highest yet unrealizable end. (shrink)

This paper presents a recent formalization of a Henkin-style completeness proof for the propositional modal logic S5 using the Lean theorem prover. The proof formalized is close to that of Hughes and Cresswell, but the system, based on a different choice of axioms, is better described as a Mendelson system augmented with axiom schemes for K, T, S4, and B, and the necessitation rule as a rule of inference. The language has the false and implication as the only primitive logical (...) connectives and necessity as the only primitive modal operator. The full source code is available online and has been typechecked with Lean 3.4.2. (shrink)

The history of philosophy risks a self-opacity whereby we overestimate or underestimate our proximity to prior modes of thinking. This risk is relevant to assessing Hegel’s appropriation by McDowell and Priest. McDowell enlists Hegel for a quietist answer to the problem with assuming that concepts and reality belong to different orders, viz., how concepts are answerable to the world. If we accept Hegel’s absolute idealist view that the conceptual is boundless, this problem allegedly dissolves. Priest enlists Hegel for a dialetheist (...) answer to the problem with assuming that truth and falsity are mutually exclusive, viz., how certain sentences are both true and false. If we accept Hegel’s dialectical view that certain contradictions are necessary, this problem allegedly dissolves. For both McDowell and Priest, we find a true friend in Hegel. I argue that McDowell’s and Priest’s appropriations of Hegel overestimate Hegel’s affinity with quietism and dialetheism. McDowell reads Hegel as a quietist who silences metaphysical claims and the skeptical questions they raise against commonsense, but neglects Hegel’s adaptation of ancient skepticism against commonsense. Priest reads Hegel as a dialetheist who subordinates formal logic to dialectical logic by affirming the truth of certain contradictions, but neglects Hegel’s commitment to resolving contradictions for the sake of truth qua whole. I diagnose their misreadings in terms of what Hegel regards as the three moments of logic and argue that while McDowell jumps to its third moment, Priest stalls at its second moment. According to Hegel’s Encyclopedia Logic, logic has three “moments”: the abstractive moment of the understanding, which “stops short” at fixed categories; the negative moment of dialectic, which discovers the “genuine nature” of the categories, viz., that each “passes over, of itself, into its opposite”; and the positive moment of speculation, which grasps the “unity” of categories through the “dissolution” of their inner opposition. Hegel warns that if these moments are “kept separate from each other […] they are not considered in their truth”. I suggest that quietist and dialetheist readings of Hegel fail to consider truthfully the unified moments of his logic. In his quietist critique of metaphysics, McDowell enlists Hegel to dissolve the problem with assuming the duality of concept and reality. But McDowell helps himself directly to the third moment of logic, where the unity of the categories, and hence the boundlessness of the conceptual, would be fully articulated. Since he arrives at the third moment prematurely, ignoring its prior moments, he obscures its truth (§1). In his dialetheist critique of formal logic, Priest enlists Hegel to dissolve the problem with assuming the duality of truth and falsity. But Priest restricts himself gratuitously to the second moment of logic, where contradictions within the categories are not yet resolved. Since he stalls at the second moment, severed from its final moment, he obscures its truth (§2). I argue we can extricate Hegel from quietist and dialetheist misreadings only if we grasp the truth of the three moments of logic. (shrink)

This article proposes a way of doing type theory informally, assuming a cubical style of reasoning. It can thus be viewed as a first step toward a cubical alternative to the program of informalization of type theory carried out in the homotopy type theory book for dependent type theory augmented with axioms for univalence and higher inductive types. We adopt a cartesian cubical type theory proposed by Angiuli, Brunerie, Coquand, Favonia, Harper, and Licata as the implicit foundation, confining our presentation (...) to elementary results such as function extensionality, the derivation of weak connections and path induction, the groupoid structure of types, and the Eckmman–Hilton duality.

Kripke [1975] gives a formal theory of truth based on Kleene's strong evaluation scheme. It is probably the most important and influential that has yet been given—at least since Tarski. However, it has been argued that this theory has a problem with generalized quantifiers such as All—that is, All ϕs are ψ—or Most. Specifically, it has been argued that such quantifiers preclude the existence of just the sort of language that Kripke aims to deliver—one that contains its own truth predicate. (...) In this paper I solve the problem by showing how Kleene's strong scheme, and Kripke's theory based on it, can in a natural way be extended to accommodate the full range of generalized quantifiers.

Philosophical discussions of Molyneux's problem within contemporary philosophy of mind tend to characterize the problem as primarily concerned with the role innately known principles, amodal spatial concepts, and rational cognitive faculties play in our perceptual lives. Indeed, for broadly similar reasons, rationalists have generally advocated an affirmative answer, while empiricists have generally advocated a negative one, to the question Molyneux posed after presenting his famous thought experiment. This historical characterization of the dialectic, however, somewhat obscures the role Molyneux's problem has (...) played in spawning debates within the empiricist tradition. Fortunately, the differences between various empiricist accounts have been widely recognized and discussed among historians of philosophy working on the topic. The focus of the present essay is to develop an interpretation of John Locke's views on Molyneux's problem that best coheres with his other views on human understanding as well as with the predominant scientific opinion about the nature of perception during the period in which he lived.

Are there different sizes of infinity? That is, are there infinite sets of different sizes? This is one of the most natural questions that one can ask about the infinite. But it is of course generally taken to be settled by mathematical results, such as Cantor’s theorem, to the effect that there are infinite sets without bijections between them. These results settle the question, given an almost universally accepted principle relating size to the existence of functions. The principle is: for (...) any sets A and B, if A is the same size as B, then there is a bijection from A to B. The aim of the paper, however, is to argue that this question is in fact wide open: to argue that we are not in a position to know the answer, because we are not in one to know the principle. The aim, that is, is to argue that for all we know there is only one size of infinity. (shrink)

I discuss problems with Martin-Löf's distinction between analytic and synthetic judgments in constructive type theory and propose a revision of his views. I maintain that a judgment is analytic when its correctness follows exclusively from the evaluation of the expressions occurring in it. I argue that Martin-Löf's claim that all judgments of the forms a : A and a = b : A are analytic is unfounded. As I shall show, when A evaluates to a dependent function type (x : (...) B) → C, all judgments of these forms fail to be analytic and therefore end up as synthetic. Going beyond the scope of Martin-Löf's original distinction, I also argue that all hypothetical judgments are synthetic and show how the analytic-synthetic distinction reworked here is capable of accommodating judgments of the forms A type and A = B type as well. Finally, I consider and reject an alternative account of analyticity as decidability and assess Martin-Löf's position on the analytic grounding of synthetic judgments. (shrink)

It is often claimed that the theory of function levels proposed by Frege in Grundgesetze der Arithmetik anticipates the hierarchy of types that underlies Church’s simple theory of types. This claim roughly states that Frege presupposes a type of functions in the sense of simple type theory in the expository language of Grundgesetze. However, this view makes it hard to accommodate function names of two arguments and view functions as incomplete entities. I propose and defend an alternative interpretation of first-level (...) function names in Grundgesetze into simple type-theoretic open terms rather than into closed terms of a function type. This interpretation offers a still unhistorical but more faithful type-theoretic approximation of Frege’s theory of levels and can be naturally extended to accommodate second-level functions. It is made possible by two key observations that Frege’s Roman markers behave essentially like open terms and that Frege lacks a clear criterion for distinguishing between Roman markers and function names.

Quanto segue intende proporsi come il resoconto di una conversazione che Andrea Oliani, Bruno Cortesi e Pietro Vigiani, tutti studenti presso l’Almo Collegio Borromeo di Pavia, hanno intrattenuto con Emanuele Severino, volta ad enucleare, muovendo da spunti talvolta anche polemici, alcune delle concettualità fondanti quel corpus di dottrine che cade sotto il nome di severinismo. Severino è stato squisito nell’accoglierci e ospitarci nella sua dimora di Brescia, lucido e assolutamente puntuale nel controbattere alle nostre provocazioni. La discussione ha poi (...) trovato naturale seguito in una conferenza di carattere più divulgativo tenuta dal filosofo presso il Collegio Borromeo, dal titolo Sulla Tecnica. Severino consegue la laurea in Filosofia nel 1950 come alunno del Collegio Borromeo, discutendo una tesi intitolata Heidegger e la metafisica sotto la supervisione di Gustavo Bontadini. Solo un anno più tardi ottiene la libera docenza in filosofia teoretica. Nel 1964 pubblica lo scritto Ritornare a Parmenide, che, insieme a La Struttura Originaria rappresenta la miccia che innescherà negli anni successivi quello che molti hanno definito lo “scandalo” del severinismo. Questi scritti, come altri, posseggono una portata teorica tanto dirompente che già nel 1969, a seguito di un lungo e accurato esame condotto da Cornelio Fabro, la Chiesa cattolica proclamerà l’insanabile pposizione tra il pensiero di Severino e il Cristianesimo. Comprendere tale pensiero è cosa ardua, se prima non ci sia volti alla grecità delle origini: essa è, per Severino, il luogo ove in maniera inaudita (nel senso letterale di “mai udita prima”) viene pensato l’Incontrovertibile, il “Sempre Salvo”, ciò la cui egazione è auto-negazione, e che pertanto non può in alcun modo essere contraddetto; In altri termini: la Verità. Essa è anche stata in grado per la prima volta di concepire in maniera radicale L’Essere e il suo corrispettivo: il Niente inteso come radicale assenza di qualsiasi positività. L’aver inteso la Verità come Saphés (“Ciò che brilla di luce propria” da cui Philo-Sophìa) da un lato, e l’aver posto L’Essere e il Niente dall’altro, sono gli atti che per Severino fondano quell’immenso edificio culturale che ancora oggi domina il pianeta tutto: L’Occidente. È possibile, dunque, individuare una pars construens e una pars destruens negli scritti di Emanuele Severino: da una parte sembra che, facendo uso di un apparato logico e ontologico raffinatissimo, egli cerchi di porre in questione le categorie di pensiero occidentali risolvendo il Problema dell’Occidente alla radice, cioè eliminandolo (accenneremo a quale sia questo problema e a cosa significhi eliminarlo); in questa che è una vera e propria opera di demolizione, il Nostro (pars construens) intende mostrare come tutto quanto si mostra nell’orizzonte esperienziale sia “da sempre salvo” perché eterno. Ciò sfocia, in scritti quali Pensieri sul Cristianesimo, Technè, Il Giogo, Il Nulla e la Poesia, in una “ricostruzione” volta a mostrare come le categorie introdotte dal pensiero greco si riverberino in ogni forma della razionalità occidentale, dall’arte, alla filosofia, al diritto, alla politica, determinandone in maniera necessaria gli sviluppi. Precisiamo, per correttezza, che lo stesso non è stato rivisto da Severino. (shrink)

This article offers a libertarian re-examination of Brazilian political history focusing mainly on the first few decades of the 19th century. The article finds two main tendencies lurking behind the various political parties and labels of the time: one, associated mainly with the Conservative Party, leaned dangerously away from the individual liberties advocated by classical liberalism and instead more toward authoritarian forms of government. The other, associated mainly with the Liberal Party, was more libertarian in nature. This article also concludes (...) that other examinations of these budding political parties fall short by overlooking a potentially authoritarian state underlying the Conservative project that dominated politics in Brazil at the time.

The extent of the originality and relevance of Kant's ethics is undeniable. But it is not so evident the fact that the Kant's moral philosophy as a whole was not suddenly built, but it was dependent on a profound debate with the philosophical tradition, especially with the German scholastic tradition, a debate which led to the assimilation or appropriation of several of its aspects. With special regard to the history of the development of the categorical imperative, it is not possible (...) to be indifferent to the influence of the practical philosophy of the Enlightenment German philosopher and theologian, Christian August Crusius. The aim of this article is thus to try to identify, taking into account the distinction of praxis in problematic and moral and the contrast between prudence and morality, some points of intersection between the moral philosophy of Crusius and Kant in its origin.
