These are the first two chapters from a monograph (The Time Flow Manifesto, Holster, 2013-14; unpublished), defending the concepts of time directionality and time flow in physics and naturalistic metaphysics, against long-standing attacks from the ‘conventional philosophy of physical time’. This monograph sets out to disprove twelve specific “fallacies of the conventional philosophy”, stated in the first section below. These are the foundational principles of the conventional philosophy, which developed in the mid-C20th from positivist-inspired studies. The (...) first chapter begins by re-presenting the basic analysis of time reversal symmetry in the context of probabilistic or non-deterministic processes, removing the first critical error in the conventional account. The second chapter argues for a law-like explanation of physical time asymmetry and irreversibility, and shows how the ‘reversibility paradoxes’ are explained. (shrink)

The Principle of Sufficient Reason is very seldom, if ever, referred to in the works of whom we might think of as the eminent Asian metaphysicians. In spite of this, the big picture metaphysical views available in the thought of philosophers such as Nāgārjuna, Fazang and Nishida appear to share certain structural features with views more familiar to us from our own tradition; views that explicitly accept or reject the Principle of Sufficient Reason. Nāgārjuna looks to develop a kind of (...) metaphysical infinitism, Fazang an extreme form of coherentism, and Nishida a species of foundationalism. These three positions - infinitism, coherentism and foundationalism - are typically thought to exhaust the spread of possibilities by those working within the Western tradition. -/- In spite of their similarities to positions advanced within our own tradition, the cosmologies of many of the giants of Asian philosophy are characterised by their rather striking conclusions. Amongst such conclusions for Nāgārjuna is that everything is empty; for Fazang that everything is identical to everything else; and for Nishida that everything depends on absolute nothingness. If the Principle of Sufficient Reason is playing a role in the derivation of such striking conclusions, then it looks that there are more options regarding the metaphysical structure of the world available to us than our own tradition typically courts. If, on the other hand, these striking cosmological conclusions are arrived at without any consideration of sufficient reason, then there may well be ways of reasoning about the overarching structure of reality that are powerful but unfamiliar to Western thinking. In this contribution, I explore what, if any, role the PSR might be playing in the thought of Nāgārjuna , Fazang and Nishida, and what we might be able to learn from it. (shrink)

Linear Algebra is an extremely important field that extends everyday concepts about geometry and algebra into higher spaces. This text serves as a gentle motivating introduction to the principles (and philosophy) behind linear algebra. This is aimed at undergraduate students taking a linear algebra class - in particular engineering students who are expected to understand and use linear algebra to build and design things, however it may also prove helpful for philosophy majors and anyone else interested in (...) the ideas behind linear algebra. Linear algebra is used extensively in statistics, mechanical engineering, circuit theory, signal processing, economics and data science/machine learning. I have found in my teaching career that students tend to struggle the most with motivating the "why" behind the abstract concepts discussed in linear algebra. This can be difficult for professors to understand because we are so used to using the language of linear algebra we take for granted why these questions are important in the first place. In other words, we may understand the “why” (after years of using these tools), but our students may not. This text seeks to explain this “why” in an accessible, engaging way. (shrink)

The Principle of Analogy. ABSTRACT. Sceptics question whether ‘distinctively human’ predicates such as ‘just’, ‘loving’ and ‘powerful’ can intelligibly be attributed to a divine being. If not, then a vicious form of agnosticism seems to threaten orthodox theism. Especially if one assumes a broadly empiricist semantics the challenge, whether formulated in terms of a univocal or an equivocal understanding of predicates, seems to generate intractable philosophical problems. Aquinas’ theory of analogical predication, understood either in terms of ‘analogy duorum ad tertium’ (...) or in terms of ‘analogy unus ad alterum’, is an influential response to this sceptical challenge. Difficulties in each understanding are explored and it is suggested that a more fruitful framework for understanding theistic language is to be found in late 20th century nativism of Fodor and Quine.

The principle of indifference states that in the absence of any relevant evidence, a rational agent will distribute their credence equally among all the possible outcomes under consideration. Despite its intuitive plausibility, PI famously falls prey to paradox, and so is widely rejected as a principle of ideal rationality. In this article, I present a novel rehabilitation of PI in terms of the epistemology of comparative confidence judgments. In particular, I consider two natural comparative reformulations of PI and argue that (...) while one of them prescribes the adoption of patently irrational epistemic states, the other provides a consistent formulation of PI that overcomes the most salient limitations of existing formulations.

Leibniz was a philosopher of principles: the principles of Contradiction, of Sufficient Reason, of Identity of Indiscernibles, of Plenitude, of the Best, and of Continuity are among the most famous Leibnizian principles. In this article I shall focus on the first three principles; I shall discuss various formulations of the principles (sect. 1), what it means for these theses to have the status of principles or axioms in Leibniz’s philosophy (sect. 2), the fundamental (...) character of the Principles of Contradiction and Sufficient Reason (sect. 3), some attempts to demonstrate the Principles of Contradiction and Sufficient Reason (sect. 4), and one attempt to demonstrate the Principle of Identity of Indiscernibles (sect. 5). The main results of the chapter are summarized in a short conclusion (sect. 6). (shrink)

In this essay, “The Principle of Autonomy in Kant’s Moral Theory: Its Rise and Fall,” Pauline Kleingeld notes that Kant’s Principle of Autonomy, which played a central role in both the Groundwork for the Metaphysics of Morals and the Critique of Practical Reason, disappeared by the time of the Metaphysics of Morals. She argues that its disappearance is due to significant changes in Kant’s political philosophy. The Principle of Autonomy states that one ought to act as if one were (...) giving universal laws through one’s maxims. The criterion of just legislation that Kant accepted in the mid-1780s does not require any actual consent on the part of the citizens—genuine universality is sufficient for a law to be just. Hence, at that time, Kant could indeed explicate the criterion governing the moral permissibility of one’s maxims by drawing an analogy with the criterion governing the justice of political laws. In the Metaphysics of Morals and in other works in the 1790s, however, he added the further condition that laws must be given with the consent of the citizens. With this further condition, the moral criterion was no longer fully analogous to the criterion for political laws being just. Accordingly, Kleingeld argues, Kant dropped the Principle of Autonomy, which was firmly based on that analogy. (shrink)

Sometimes different partitions of the same space each seem to divide that space into propositions that call for equal epistemic treatment. Famously, equal treatment in the form of equal point-valued credence leads to incoherence. Some have argued that equal treatment in the form of equal interval-valued credence solves the puzzle. This paper shows that, once we rule out intervals with extreme endpoints, this proposal also leads to incoherence.

Acknowledging that Nature is one unified whole, we expect that physics and biology are intimately related. Keeping in mind that physics became an exact science with which we are already familiar with, while, apparently, we do not have at present a similar knowledge about biology, we consider how can we make useful the clarity of physics to shed light to biology. The next question will be what are the most basic categories of physics and biology. If we do not want (...) to cut laws of Nature into different parts, we obtain a constraint, and the remaining part of physics will be the input data to the equations of physics. In these terms, our question will be: if we keep biological laws intact, as indivisible units, what remains in case of biology? This approach, just because it is more fundamental, has significant consequences for philosophy, and obviously offers a new conceptual framework considering the relation between the ontopoietic principle of Anna-Teresa Tymieniecka and the biological principle. The quintessence of science, namely, the first essentially complete scientific world picture is presented in a detailed form. (shrink)

Many theorists have proposed that we can use the principle of indifference to defeat the inductive sceptic. But any such theorist must confront the objection that different ways of applying the principle of indifference lead to incompatible probability assignments. Huemer offers the explanatory priority proviso as a strategy for overcoming this objection. With this proposal, Huemer claims that we can defend induction in a way that is not question-begging against the sceptic. But in this article, I argue that the opposite (...) is true: if anything, Huemer’s use of the principle of indifference supports the rationality of inductive scepticism. (shrink)

A principle, according to which any scientific theory can be mathematized, is investigated. Social science, liberal arts, history, and philosophy are meant first of all. That kind of theory is presupposed to be a consistent text, which can be exhaustedly represented by a certain mathematical structure constructively. In thus used, the term “theory” includes all hypotheses as yet unconfirmed as already rejected. The investigation of the sketch of a possible proof of the principle demonstrates that it should be accepted (...) rather a metamathematical axiom about the relation of mathematics and reality. The main statement is formulated as follows: Any scientific theory admits isomorphism to some mathematical structure in a way constructive. Its investigation needs philosophical means. Husserl’s phenomenology is what is used, and then the conception of “bracketing reality” is modelled to generalize Peano arithmetic in its relation to set theory in the foundation of mathematics. The obtained model is equivalent to the generalization of Peano arithmetic by means of replacing the axiom of induction with that of transfinite induction. The sketch of the proof is organized in five steps: a generalization of epoché; involving transfinite induction in the transition between Peano arithmetic and set theory; discussing the finiteness of Peano arithmetic; applying transfinite induction to Peano arithmetic; discussing an arithmetical model of reality. Accepting or rejecting the principle, two kinds of mathematics appear differing from each other by its relation to reality. Accepting the principle, mathematics has to include reality within itself in a kind of Pythagoreanism. These two kinds are called in paper correspondingly Hilbert mathematics and Gödel mathematics. The sketch of the proof of the principle demonstrates that the generalization of Peano arithmetic as above can be interpreted as a model of Hilbert mathematics into Gödel mathematics therefore showing that the former is not less consistent than the latter, and the principle is an independent axiom. The present paper follows a pathway grounded on Husserl’s phenomenology and “bracketing reality” to achieve the generalized arithmetic necessary for the principle to be founded in alternative ontology, in which there is no reality external to mathematics: reality is included within mathematics. That latter mathematics is able to self-found itself and can be called Hilbert mathematics in honour of Hilbert’s program for self-founding mathematics on the base of arithmetic. The principle of universal mathematizability is consistent to Hilbert mathematics, but not to Gödel mathematics. Consequently, its validity or rejection would resolve the problem which mathematics refers to our being; and vice versa: the choice between them for different reasons would confirm or refuse the principle as to the being. An information interpretation of Hilbert mathematics is involved. It is a kind of ontology of information. The Schrödinger equation in quantum mechanics is involved to illustrate that ontology. Thus the problem which of the two mathematics is more relevant to our being is discussed again in a new way A few directions for future work can be: a rigorous formal proof of the principle as an independent axiom; the further development of information ontology consistent to both kinds of mathematics, but much more natural for Hilbert mathematics; the development of the information interpretation of quantum mechanics as a mathematical one for information ontology and thus Hilbert mathematics; the description of consciousness in terms of information ontology.

The key assumption behind evolutionary epistemology is that animals are active learners or ‘knowers’. In the present study, I updated the concept of natural learning, developed by Henry Plotkin and John Odling-Smee, by expanding it from the animal-only territory to the biosphere-as-a-whole territory. In the new interpretation of natural learning the concept of biological information, guided by Peter Corning’s concept of “control information”, becomes the ‘glue’ holding the organism–environment interactions together. The control information guides biological systems, from bacteria to ecosystems, (...) in the process of natural learning executed by the universal algorithm. This algorithm, summarized by the acronym IGPT (information-gain-process-translate) incorporates natural cognitive methods including sensing/perception, memory, communication, and decision-making. Finally, the biosphere becomes the distributed network of communicative interactions between biological systems termed the interactome. The concept of interactome is based on Gregory Bateson’s natural epistemology known as the “ecology of mind”. Mimicking Bateson’s approach, the interactome may also be designated “physiology of mind”—the principle behind regulating the biosphere homeostasis. (shrink)

This article offers a novel, conservative account of material constitution, one that incorporates sortal essentialism and features a theory of dominant sortals. It avoids coinciding objects, temporal parts, relativizations of identity, mereological essentialism, anti-essentialism, denials of the reality of the objects of our ordinary ontology, and other departures from the metaphysic implicit in ordinary ways of thinking. Defenses of the account against important objections are found in Burke 1997, 2003, and 2004, as well as in the often neglected six paragraphs (...) that conclude section V of this article. (shrink)

Basal cognition investigates cognition working upward from nonneuronal organisms. Because basal cognition is committed to empirically testable hypotheses, a methodological challenge arises: how can experiments avoid using zoocentric assumptions that ignore the ecological contexts that might elicit cognitively driven behavior in nonneuronal organisms? To meet this challenge, I articulate the principle of dynamic holism (PDH), a methodological principle for guiding research on nonneuronal cognition. I describe PDH’s relation to holistic research programs in human-focused cognitive science and psychology then present an (...) argument from analogy based on holistic developmental biology. Last, I examine two experiments exemplifying the need for PDH. (shrink)

Recent debate in the literature on political obligation about the principle of fairness rests on a mistake. Despite the widespread assumption to the contrary, a person can have a duty of fairness to share in the burdens of sustaining some cooperative scheme even though that scheme does not represent a net benefit to her. Recognizing this mistake allows for a resolution of the stalemate between those who argue that the mere receipt of some public good from a scheme can generate (...) a duty of fairness and those who argue that only some voluntary action of consent or acceptance of the good can generate such a duty. I defend a version of the principle of fairness that holds that it is the person’s reliance on a scheme for the provision of some product or service that generates duties of fairness to share in the burdens of sustaining the scheme. And, on this version, the principle of fairness is politically significant: regardless of whether the citizen has a duty to obey the law, she will still have important political duties of fairness generated by her reliance on the various public goods provided by those society-wide cooperative schemes sustained by the sacrifices of her fellow citizens.

Despite the importance of the variational principles of physics, there have been relatively few attempts to consider them for a realistic framework. In addition to the old teleological question, this paper continues the recent discussion regarding the modal involvement of the principle of least action and its relations with the Humean view of the laws of nature. The reality of possible paths in the principle of least action is examined from the perspectives of the contemporary metaphysics of modality and (...) Leibniz's concept of essences or possibles striving for existence. I elaborate a modal interpretation of the principle of least action that replaces a classical representation of a system's motion along a single history in the actual modality by simultaneous motions along an infinite set of all possible histories in the possible modality. This model is based on an intuition that deep ontological connections exist between the possible paths in the principle of least action and possible quantum histories in the Feynman path integral. I interpret the action as a physical measure of the essence of every possible history. Therefore only one actual history has the highest degree of the essence and minimal action. To address the issue of necessity, I assume that the principle of least action has a general physical necessity and lies between the laws of motion with a limited physical necessity and certain laws with a metaphysical necessity.

This article discusses Heidegger’s interpretation of Parmenides given in his last public lecture ‘The Principle of Identity’ in 1957. The aim of the piece is to illustrate just how original and significant Heidegger’s reading of Parmenides and the principle of identity is, within the history of Philosophy. Thus the article will examine the traditional metaphysical interpretation of Parmenides and consider G.W.F. Hegel and William James’ account of the principle of identity in light of this. It will then consider Heidegger’s (...) contribution, his return to and re-interpretation of Parmenides in his last lecture. Heidegger will, through the Parmenidean claim that ‘Thinking and Being are one’ deconstruct the traditional metaphysical understanding of the principle of identity, and in its place offer a radically different conception of how our relationship, our ‘belonging together’ with Being can be understood.

This is the second chapter of my book Transformation of the Self. It concerns Schleiermacher's understanding of the principle of individuation, in dialogue with Kant, Jacobi, Leibniz and Spinoza.

I argue that Émilie Du Châtelet breaks with Christian Wolff regarding the scope and epistemological content of the principle of sufficient reason, despite his influence on her basic ontology and their agreement that the principle of sufficient reason has foundational importance. These differences have decisive consequences for the ways in which Du Châtelet and Wolff conceive of science.

In this article the possibilities of expanding the boundaries of the knowledge and tradition of art philosophy in Turkey through the works of names outside the discipline of philosophy are investigated. For this purpose the production of architectural historian Doğan Kuban is discussed. Kuban’s works are evaluated from a philosophical perspective and it is tried to justify that they should be included in the philosophy of art literature. It has been accepted by the researchers that aesthetics/philosophy (...) of art in Turkey started with the effect of westernization after the Tanzimat. The main problems of the few studies that follow the development of aesthetics are that they examine aesthetics, which developed mainly through literary figures and philosophers who had less space than them, until the establishment of the Republic, only through the works of professional philosophers since the Republic, and they exclude the idea of tradition by not establishing a connection between the local thinkers they have examined and ending their development line with İsmail Tunalı. Common problems in research create the impression that the acceptance of aesthetics or philosophy of art as an activity that only the philosopher can do is accepted as a prejudice. However, philosophy of art is not a field specific to philosophers and limiting the development and accumulation of philosophy of art in Turkey to the work of philosophers narrows the scope of discussion. When a philosophical approach to the subject is sought other than philosophers, the opportunity to meet important names in different disciplines and to read them with a new eye increases. When approached from this perspective, Doğan Kuban’s (1926-2021) works deserve to be questioned in terms of art philosophy. It is noteworthy that Kuban’s production which started in the 1950s and lasted for about 70 years presents a wide field of data and interpretation and that he often attempts theory by reminding the absence of criticism and philosophy in our culture. There are also thinkers who refer to Kuban’s interest in philosophy, aesthetics and philosophy of art. However, Kuban’s relevance to philosophy and aesthetics/art philosophy has not been studied extensively. In the article firstly answers will be sought to the questions of what philosophy and philosophy of art are, and then Kuban’s philosophy of art will be revealed according to the criteria to be determined here. Kuban’s philosophy of art will be examined in three stages. His own theoretical approach will be analyzed by reviewing his objections to the tradition of philosophy of art. In the next step, his views on the philosophy of architecture and the philosophy of Turkish art, which he pursued throughout his production as a quest, will be examined. Finally the problems in Kuban’s philosophy of art will be pointed out and its possibilities will be emphasized. Philosophy is the ability to redefine the concepts starting from the most basic/original problems in any field where one doubts the answers, to determine the principles of the field, to answer the sub-questions with principles in line with consistency and validity, and to construct his own explanation model for the structure of the field by associating these answers. In order to make philosophy of art and philosophy of architecture it is necessary to answer the basic questions of the relevant field, to reach conceptual and principled goals, and to present a model of explanation of the structure of the field within a certain method. In the context of the criteria of art philosophy determined here, Kuban’s thoughts can be questioned in terms of philosophy of art. The philosophy of art, the philosophy of architecture and the philosophy of Turkish art, which became evident by the bringing together of different pieces in Kuban’s works, is a continuous and mutually determined effort. The thinker who criticizes the thinking styles and provisions of Western aesthetics, has created his own concept map with redefinitions and conceptualizations. Kuban redefined the concepts in the field of study, based on these he constructed his understanding of art, the philosophy of architecture and tried to create a model of explanation of Turkish art in which he revealed its history, evolution and basic features. Criticizing the views of C. E. Arseven, J. Strzygowski, E. Diez and O. Aslanapa, Kuban tried to define Turkish art in his own way and tried to explain the basic principles of Turkish art through monumental and civil architecture. Even though this model of explanation has deficiencies it offers new research opportunities to history of art and philosophy researchers with the questions it asks, the concepts it highlights and its unresolved aspects. With his philosophical awareness, criticisms of the philosophy of art, the philosophy of architecture and the attempt to construct the theory of Turkish art, Kuban should be included in the subject area of the philosophy of art studies in Turkey. Evaluation of Kuban’s thoughts by including them in the accumulation of art philosophy in our history of thought will both broaden and diversify the horizon of the field of art philosophy and will enable the philosophy of art to be considered in the context of new relationships between individuals and disciplines by following the traces of thinkers from such different fields.

This article presents the proposal of the principle of sound and light from mathematics and physics, as the origin of nature and the universe, using the Cartesian plane, together with the triadic plane of potential manifestation and complex organisation, starting from the contributions of four pre-Socratic philosophers, Pythagoras of Ephesus, Parmenides of Elea, Heraclitus of Samos and Democritus of Abdera, thus identifying essential principles of the origin of these, to conclude with the most important demonstrations of this theory, which (...) allow its articulation with current science.

The topic of this paper may be introduced by fast zooming in and out of the philosophy of information. In recent years, philosophical interest in the nature of information has been increasing steadily. This has led to a focus on semantic information, and then on the logic of being informed, which has attracted analyses concentrating both on the statal sense in which S holds the information that p (this is what I mean by logic of being informed in the (...) rest of this article) and on the actional sense in which S becomes informed that p. One of the consequences of the logic debate has been a renewed epistemological interest in the principle of information closure (henceforth PIC), which finally has motivated a revival of a skeptical objection against its tenability first made popular by Dretske. This is the topic of the paper, in which I seek to defend PIC against the skeptical objection. If I am successful, this means – and we are now zooming out – that the plausibility of PIC is not undermined by the skeptical objection, and therefore that a major epistemological argument against the formalization of the logic of being informed based on the axiom of distribution in modal logic is removed. But since the axiom of distribution discriminates between normal and non-normal modal logics, this means that a potentially good reason to look for a formalization of the logic of being informed among the non-normal modal logics, which reject the axiom, is also removed. And this in turn means that a formalization of the logic of being informed in terms of the normal modal logic B (also known as KTB) is still very plausible, at least insofar as this specific obstacle is concerned. In short, I shall argue that the skeptical objection against PIC fails, so it is not a good reason to abandon the normal modal logic B as a good formalization of the logic of being informed.

The idea that healthcare should become more person-centred is extremely influential. By using recent English policy developments as a case study, this article aims to critically analyse an important element of person-centred care, namely, the belief that to treat patients as persons is to think that care should be ‘co-produced’ by formal healthcare providers and patients together with unpaid carers and voluntary organizations. I draw on insights from political philosophy to highlight overlooked tensions between co-production and values like equality (...) and liberty. Regarding equality, I argue that co-production compounds both problems of gender inequality in the distribution of care labour and the challenges associated with securing equal access to care. Turning to liberty, I identify important commonalities between co-production and republicanism in political philosophy, given their shared insistence on common citizens’ civic virtue. Then, I use against co-production some liberal arguments against republicanism, to highlight a problem of over-demandingness. In bringing my argument to a close, however, I wish to caution against hastily rejecting co-production as a policy programme. (shrink)

This paper defends the Principle of Sufficient Reason, taking Baumgarten as its guide. The primary aim is not to vindicate the principle, but rather to explore the kinds of resources Baumgarten originally thought sufficient to justify the PSR against its early opponents. The paper also considers Baumgarten’s possible responses to Kant’s pre-Critical objections to the proof of the PSR. The paper finds that Baumgarten possesses reasonable responses to all these objections. While the paper notes that in the absence of a (...) response to Kant’s Critical discussion of the PSR, this result does not vindicate the principle, it shows how this discussion provides a deeper understanding of what, according to Baumgarten, the PSR really assumes and intends, and prepares the way for a more responsible discussion of Kant’s critical objections to Baumgarten’s supposed proof.

Canonical defenders of the principle of sufficient reason (PSR), such as Leibniz and Spinoza, are metaphysical foundationalists of one stripe or another. This is curious since the PSR—which says that everything has a ground, cause, or explanation—in effect, denies fundamental entities. In this paper, I explore the apparent inconsistency between metaphysical foundationalism and approaches to metaphysical system building that are driven by a commitment to the PSR. I do so by analyzing how Indian Buddhist philosophers arrive at foundationalist and anti-foundationalist (...) positions motivated by implicit commitments to different versions of the PSR. I begin by introducing the Buddhist principle of dependent origination (pratītyasamutpāda) as a proto-PSR that is restricted to causal explanation. Next, I show how Vasubandhu’s Sautrāntika Abhidharma metaphysics is shaped by a qualified commitment to both causal and metaphysical grounding versions of the PSR. I then reveal how Nāgārjuna’s Madhyamaka metaphysics is driven by an unrestricted and exceptionless commitment to causal and metaphysical grounding versions of the PSR. Finally, I consider how Nāgārjuna’s account may put him in a unique position to respond to a common contemporary objection to the PSR from necessitarianism. I conclude by addressing a competing interpretation on which Nāgārjuna is best understood as an anti-rationalist rather than an uber-rationalist, as I characterize him. (shrink)

The aim of this paper is to begin a conversation about how we read and write about Nietzsche and, related to this, other figures in the history of philosophy. The principle of charity can appear to be a way to bridge two dif-ferent interpretative goals: getting the meaning of the text right and offering the best philosophy. I argue that the principle of charity is multiply ambiguous along three different dimensions, which I call “unit,” “mode,” and “strength”: consequently, (...) it is not a single, neutral or independent principle to which we can helpfully appeal and it cannot, in itself, perform this bridging function. Nietzsche, I suggest, is particularly ill suited to some forms of charitable reading. I compare charity to what I call “misreporting” a philosopher’s words, in order to highlight some problematic structural similarities. Finally, I assess what charity might be doing instead, if it is not intended to bridge meaning and best philosophy. (shrink)

This paper presents a new solution to the problem of peer disagreement that distinguishes two principles of rational belief, here called probability and autonomy. When we discover that we disagree with peers, there is one sense in which we rationally ought to suspend belief, and another in which we rationally ought to retain our original belief. In the first sense, we aim to believe what is most probably true according to our total evidence, including testimony from peers and authorities. (...) In the second, we aim to base our beliefs only on objective evidence and argumentation, even if that lowers the probability of their being true. The first principle of rational belief tends to serve the short-term epistemic interests of individuals, while the second tends to serve the long-term epistemic interests of both individuals and groups. The best way to reconcile these principles in cases of peer disagreement is to associate them with two corresponding species of belief, here called perception and opinion. (shrink)

In Bertrand Russell's 1903 Principles of Mathematics, he offers an apparently devastating criticism of the neo-Kantian Hermann Cohen's Principle of the Infinitesimal Method and its History (PIM). Russell's criticism is motivated by his concern that Cohen's account of the foundations of calculus saddles mathematics with the paradoxes of the infinitesimal and continuum, and thus threatens the very idea of mathematical truth. This paper defends Cohen against that objection of Russell's, and argues that properly understood, Cohen's views of limits and (...) infinitesimals do not entail the paradoxes of the infinitesimal and continuum. Essential to that defense is an interpretation, developed in the paper, of Cohen's positions in the PIM as deeply rationalist. The interest in developing this interpretation is not just that it reveals how Cohen's views in the PIM avoid the paradoxes of the infinitesimal and continuum. It also reveals some of what is at stake, both historically and philosophically, in Russell's criticism of Cohen. (shrink)

The thesis that rationality consists in the straight-forward maximization of utility has not lacked critics. Typically, however, detractors reject the Humean picture of rationality upon which it seems based; they seek to emancipate reason from the tyranny of the passions. It is, then, noteworthy when an attack on this thesis comes from ‘within the ranks.’David Gauthier's paper ‘Reason and Maximization’ is just such an attack; and for this reason, among others, it is interesting. It is not successful, though. In defense (...) of this conclusion, we shall begin by relating the essentials of Gauthier's argument. Then we shall examine in some detail Gauthier's claim that the principle of straighforward max-imization fails to be self-supporting. We shall argue that Gauthier's defense of this claim is at best incomplete. Finally, we shall show that the fact that a normative principle is self-subverting or non-self-supporting does not entail that the principle is defective. (shrink)

In 1969 Harry Frankfurt published his hugely influential paper 'Alternate Possibilities and Moral Responsibility' in which he claimed to present a counterexample to the so-called 'Principle of Alternate Possibilities' ('a person is morally responsible for what he has done only if he could have done otherwise'). The success of Frankfurt-style cases as counterexamples to the Principle has been much debated since. I present an objection to these cases that, in questioning their conceptual cogency, undercuts many of those debates. Such cases (...) all require a counterfactual mechanism that could cause an agent to perform an action that he cannot avoid performing. I argue that, given our concept of what it is for someone to act, this requirement is inconsistent. Frankfurt-style alleged counterexamples are cases where an agent is morally responsible for an action he performs even though, the claim goes, he could not have avoided performing that action. However, it has recently been argued, e.g. by John Fischer, that a counterexample to the Principle could be a 'Fischer-style case', i.e. a case where the agent can either perform the action or do nothing else. I argue that, although Fischer-style cases do not share the conceptual flaw common to all Frankfurt-style cases, they also fail as counterexamples to the Principle. The paper finishes with a brief discussion of the significance of the Principle of Alternate Possibilities. (shrink)

The principle of maximal entropy (further abbreviated as “MaxEnt”) can be founded on the formal mechanism, in which future transforms into past by the mediation of present. This allows of MaxEnt to be investigated by the theory of quantum information. MaxEnt can be considered as an inductive analog or generalization of “Occam’s razor”. It depends crucially on choice and thus on information just as all inductive methods of reasoning. The essence shared by Occam’s razor and MaxEnt is for the relevant (...) data known till now to be postulated as an enough fundament of conclusion. That axiom is the kind of choice grounding both principles. Popper’s falsifiability (1935) can be discussed as a complement to them: That axiom (or axiom scheme) is always sufficient but never necessary condition of conclusion therefore postulating the choice in the base of MaxEnt. Furthermore, the abstraction axiom (or axiom scheme) relevant to set theory (e.g. the axiom scheme of specification in ZFC) involves choice analogically. (shrink)

The recently much discussed phenomenon of testimony as a social source of knowledge plays a crucial justificatory role in Richard Swinburne's philosophy of religion. Although Swinburne officially reduces his principle of testimony to the criterion of simplicity and, therefore, to a derivative epistemic source, we will show that simplicity does not play the crucial role in this epistemological context. We will argue that both Swinburne's philosophical ideas and his formulations allow for a fundamental epistemic principle of testimony, by showing (...) that Swinburne has already implicitly justified the use of testimony as an epistemic source via his fundamental a priori principle of credulity.

This article presents a new reading of Fichte’s aesthetics that differs from a primarily functionalist interpretation of the imagination and art. It demonstrates that the “hovering” (Schweben) of the creative imagination should be viewed as the first principle of Fichte’s aesthetics, in which the latter consists of a triad of the pleasant, the beautiful and the sublime. Moreover, it argues that in the text Ueber Geist und Buchstab in der Philosophie (1795/1800) Fichte created a real and original monogram of the (...) hovering creative imagination, a monogram whose theoretical basis stems from Kant’s concept of the monogram in the 1st Critique as a “wavering sketch”. It contends that this overlooked but key artistic and practical example of a monogram opens up new perspectives for Fichtean aesthetics, further confirming that its first principle should be explicitly identified with the theory of the hovering imagination in the Grundlage der gesammten Wissenschaftslehre of 1794/95.

This paper examines the position in moral philosophy that Harry Frankfurt calls the Principle of Alternate Possibilities (PAP). The paper first describes the principle as articulated by A.J. Ayer. Subsequently, the paper examines Frankfurt’s critique and proposed revision of the principle and argues that Frankfurt’s proposal relies on an excessively simplistic account of practical reasoning, which fails to account for the possibility of moral dilemmas. In response, the paper offers a further revision of PAP, which accounts for Frankfurt’s critique, (...) moral dilemmas, and the challenge of causal determinism. (shrink)

This paper articulates a general distinction between two important communicative ideals—expressive sincerity and discursive integrity—and then uses it to analyze problems with political debate in contemporary democracies. In the context of philosophical discussions of different forms of trustworthiness and debates about deliberative democracy, self-knowledge, and moral testimony, the paper develops three arguments for the conclusion that, although expressive sincerity is valuable, we should not ignore discursive integrity in thinking about how to address problems with contemporary political debate. The paper concludes (...) with a brief discussion of a strategy for improving discursive integrity within public political debate by reflecting on which principles of responsible public debate would promote better democratic decision making.

Leibniz often refers to the Principle of Sufficient Reason (PSR) as something like a first principle. In some texts, however, he attempts to give positive arguments in its favor. I examine two such arguments, and find them wanting. The first argument has two defects. First, it is question-begging; and second, when the question-begging step is excised, the principle one can in fact derive is highly counter-intuitive. The second argument is valid, but has the defect of only reaching a nearly trivial (...) conclusion. (shrink)

Mulla Sadra's view of the perception of the other is the product of a profound study and serious criticism of the ideas of Peripatetics and Illuminationists, particularly those of Ibn Sina and Suhrawardi. In fact, an accurate perception of his view requires great attention to these criticisms. The importance of Mulla Sadra's criticisms lies in the fact that they are not limited only to the outward and external layers of a philosophy but continue until penetrating its inward and internal (...) layers and main principles and, in case they are defective, lead to developing new fundamental principles.According to Suhrawardi, the perception of the other is a relation. Mulla Sadra rejects this idea because of its being based on some principles which are completely unacceptable to him. Some of them include the principiality of quiddity, its gradation, and the negation of the union of the knower and the known. Mulla Sadra demonstrates the opposite of these principles and, unlike Suhrawardi, based his interpretation of the perception of the other on believing in the principiality of existence, its gradation, and the union of the knower and the known. Accordingly, he views the perception of thing not as a relation but as the presence of its form before the perceiver. Here, the form has no identity in separation from the perceiver so that we could say there is a non-relational perception between the perceiver and the perceived.The writer believes that Mulla Sadra's arguments on rejecting the argument of relation lack sufficient firmness, and a final judgment of the truth of either of these theories on perception depends on the truth of their basic principles. The acceptance of Mulla Sadra's theory depends on the strength of his arguments on denying the plurality of existents. This is because without this denial one cannot reject the ideas of relation and demonstrate the idea of the union of the knower and the known. (shrink)

The consensus is that in his 1755 Nova Dilucidatio, Kant endorsed broadly Leibnizian compatibilism, then switched to a strongly incompatibilist position in the early 1760s. I argue for an alternative, incompatibilist reading of the Nova Dilucidatio. On this reading, actions are partly grounded in indeterministic acts of volition, and partly in prior conative or cognitive motivations. Actions resulting from volitions are determined by volitions, but volitions themselves are not fully determined. This move, which was standard in medieval treatments of free (...) choice, explains why Kant is so critical of Crusius’s version of libertarian freedom: Kant understands Crusius as making actions entirely random. In defense of this reading, I offer a new analysis of the version of the principle of sufficient reason that appears in the Nova Dilucidatio. This principle can be read as merely guaranteeing grounds for the existence of things or substances, rather than efficient causes for states and events. As such, the principle need not exclude libertarian freedom. Along the way, I seek to illuminate obscure aspects of Kant’s 1755 views on moral psychology, action theory, and the threat of theological determinism. (shrink)

This chapter discusses methodology in feminist history of philosophy and shows that women philosophers made interesting and original contributions to the debates concerning the cosmological argument. I set forth and examine the arguments of Mary Astell, Damaris Masham, Catherine Trotter Cockburn, Emilie Du Châtelet, and Mary Shepherd, and discuss their involvement with philosophical issues and debates surrounding the cosmological argument. I argue that their contributions are original, philosophically interesting, and result from participation in the ongoing debates and controversies about (...) the cosmological argument, causal principles, and necessary existence.

Thomas Reid (1710–96) is increasingly being seen as a highly significant philosopher and a central figure in the Scottish Enlightenment. This new edition of Reid's classic philosophical text in the philosophy of mind at long last gives scholars a complete, critically edited text of the Inquiry. The critical text is based on the fourth life-time edition (1785). A selection of related documents showing the development of Reid's thought, textual notes, bibliographical details of previous editions and a full introduction by (...) the editor makes this an important contribution to the study of this increasingly respected philosopher. -/- Key Features - Complete, critically edited text of the Inquiry accompanied by a judicious selection of manuscript evidence relating to its composition - Comprehensive Introduction providing an historical and philosophical account of the formation of the Inquiry - Detailed textual notes which include bibliographical details and allusions, translations, references to secondary literature and selected passages from Reid's manuscripts.

The early modern period was the natural historical habitat of the Principle of Sufficient Reason, i.e., the demand that everything must have a cause, or reason. It is in this period that the principle was explicitly articulated and named, and throughout the period we find numerous formulations and variants of the PSR and its closely related ‘ex nihilo nihil fit’ principle, which the early moderns inherited from medieval philosophy. Contemporary discussions of these principles were not restricted to (...) class='Hi'>philosophy. “Nothing will come of nothing; speak again” old King Lear tells his daughter Cordelia at the beginning of Shakespeare’s celebrated tragedy, and in early modern science, conservation principles were the order of the day. Within philosophy, Malebranche stipulates that there cannot be an effect without a cause, and Berkeley motivates his idealism by an appeal to ‘ex nihilo nihil fit.’ Were we to try to provide an exhaustive survey the various formulations of the PSR in this period – including the weaker ones – we would be writing an encyclopedia. In fact, one wonders whether any early modern thinker was willing to accept a wholesale rejection of the PSR, i.e., a view which states that no fact requires an explanation. Moreover, the view that many – perhaps most – facts require an explanation seems to be tacitly assumed even by us today, in both our theoretical and colloquial discourse. For these reasons, this chapter will focus on two early modern philosophers who advocated very strong (i.e., virtually exceptionless) versions of the PSR: Benedict de Spinoza and G.W. Leibniz. Following a brief overview of Descartes’s restricted endorsement of the PSR, I will turn to discuss the central features of the PSR in the writings of Spinoza (§2) and those of Leibniz (§3). In the cases of each of these philosophers, we will examine carefully: (i) their main statements of the PSR, (ii) the scope they assign to the principle (i.e., what requires an explanation and what counts as an explanation), (iii) the modal strength they assign to the principle, (iv) the main implications they draw from the principle, (v) exceptions to the principle, and, finally, (vi) the justification of the principle. In §4, we will study a principle, complementing the PSR, namely, the assertion that everything and every fact must have an effect (or as Leibniz would put it: “nothing is sterile”). (shrink)

The principle of indifference is supposed to suffice for the rational assignation of probabilities to possibilities. Bertrand advances a probability problem, now known as his paradox, to which the principle is supposed to apply; yet, just because the problem is ill‐posed in a technical sense, applying it leads to a contradiction. Examining an ambiguity in the notion of an ill‐posed problem shows that there are precisely two strategies for resolving the paradox: the distinction strategy and the well‐posing strategy. The main (...) contenders for resolving the paradox, Marinoff and Jaynes, offer solutions which exemplify these two strategies. I show that Marinoff’s attempt at the distinction strategy fails, and I offer a general refutation of this strategy. The situation for the well‐posing strategy is more complex. Careful formulation of the paradox within measure theory shows that one of Bertrand’s original three options can be ruled out but also shows that piecemeal attempts at the well‐posing strategy will not succeed. What is required is an appeal to general principle. I show that Jaynes’s use of such a principle, the symmetry requirement, fails to resolve the paradox; that a notion of metaindifference also fails; and that, while the well‐posing strategy may not be conclusively refutable, there is no reason to think that it can succeed. So the current situation is this. The failure of Marinoff’s and Jaynes’s solutions means that the paradox remains unresolved, and of the only two strategies for resolution, one is refuted and we have no reason to think the other will succeed. Consequently, Bertrand’s paradox continues to stand in refutation of the principle of indifference. (shrink)

One of the main motivations for having a compositional semantics is the account of the productivity of natural languages. Formal languages are often part of the account of productivity, i.e., of how beings with finite capaci- ties are able to produce and understand a potentially infinite number of sen- tences, by offering a model of this process. This account of productivity con- sists in the generation of proofs in a formal system, that is taken to represent the way speakers grasp (...) the meaning of an indefinite number of sentences. The informational basis is restricted to what is represented in the lexicon. This constraint is considered as a requirement for the account of productivity, or at least of an important feature of productivity, namely, that we can grasp auto- matically the meaning of a huge number of complex expressions, far beyond what can be memorized. However, empirical results in psycholinguistics, and especially particular patterns of ERP, show that the brain integrates informa- tion of different sources very fast, without any felt effort on the part of the speaker. This shows that formal procedures do not explain productivity. How- ever, formal models are still useful in the account of how we get at the seman- tic value of a complex expression, once we have the meanings of its parts, even if there is no formal explanation of how we get at those meanings. A practice-oriented view of modeling gives an adequate interpretation of this re- sult: formal compositional semantics may be a useful model for some ex- planatory purposes concerning natural languages, without being a good model for dealing with other explananda.
