Sackris and Beebe (2014) report the results of a series of studies that seem to show that there are cases in which many people are willing to attribute knowledge to a protagonist even when her belief is unjustified. These results provide some reason to conclude that the folk concept of knowledge does not treat justification as necessary for its deployment. In this paper, we report a series of results that can be seen as supporting this conclusion by going some way (...) towards ruling out an alternative account of Sackris and Beebe’s results—the possibility that the knowledge attributions that they witnessed largely stem from protagonist projection, a phenomenon in language use and interpretation in which the speaker uses words that the relevant protagonist might use to describe her own situation and the listener interprets the speaker accordingly. With that said, we do caution the reader against drawing the conclusion too strongly, on the basis of results like those reported here and by Sackris and Beebe. There are alternative possibilities regarding what drives the observed knowledge attributions in cases of unjustified true belief that must be ruled out before, on the basis of such results, we can conclude with much confidence that the folk concept of knowledge does not treat justification as necessary for its deployment.

This entry offers a critical overview of the contemporary literature on understanding, especially in epistemology and the philosophy of science.

Hume thought that if you believed in powers, you believed in necessary connections in nature. He was then able to argue that there were none such because anything could follow anything else. But Hume wrong-footed his opponents. A power does not necessitate its manifestations: rather, it disposes towards them in a way that is less than necessary but more than purely contingent. -/- In this paper a dispositional theory of causation is offered. Causes dispose towards their effects and often produce (...) them. But a set of causes, even though they may succeed in producing an effect, cannot necessitate it since the effect could have been counteracted by some additional power. This would require a separation of our concepts of causal production and causal necessitation. The most conspicuous cases of causation are those where powers accumulate and pass a requisite threshold for an effect to occur. -/- We develop a model for representing powers as constituent vectors within an n-dimensional quality space, where composition of causes appears as vector addition. Even our resultant vector, however, has to be understood as having dispositional force only. This model throws new light on causal modality and cases of prevention, causation by absence and probabilistic causation. (shrink)

With increased visibility of trans people comes increased philosophical interest in gendered language. This chapter aims to look at the research on gendered language in analytic philosophy of language so far, which has focused on two concerns: (1) determining how to define gender terms like ‘man’ and ‘woman’ such that they are trans inclusive and (2) if, or to what extent, we should use gendered language at all. We argue that the literature has focused too heavily on how gendered language (...) can harm trans people, and has not considered how trans people use gendered language to create meaning and joy for ourselves. Pulling from the literature in sociolinguistics, we look at examples of how trans people use language to make their lives better by gaining recognition, playing with gendered language, finding joy in gendered language, and taking control of definitional power, concluding that debates about gendered language need to consider not only how such language harms trans people but also how trans people use it for our own liberation.

I argue that Schopenhauer’s ascription of (moral) rights to animals flows naturally from his distinctive analysis of the concept of a right. In contrast to those who regard rights as fundamental and then cast wrongdoing as a matter of violating rights, he takes wrong (Unrecht) to be the more fundamental notion and defines the concept of a right (Recht) in its terms. He then offers an account of wrongdoing which makes it plausible to suppose that at least many animals can (...) be wronged and thus, by extension, have rights. The result, I argue, is a perspective on the nature of moral rights in general, and the idea of animal rights in particular, that constitutes an important and plausible alternative to the more familiar views advanced by philosophers in recent decades.

In this article, from the 2009 Oxford University Press collection Epistemic Value, I criticize existing accounts of epistemic normativity by Alston, Goldman, and Sosa, and then offer a new view.

The norms of simplicity, convenience, unfussiness, and self-control guide Diogenes the Cynic, Zeno of Citium, Chrysippus, Seneca, Musonius Rufus, Epictetus, and Marcus Aurelius in approaching food. These norms generate the precept that meat and dainties are luxuries, so Stoics should eschew them. Considerations of justice, environmental harm, anthropogenic global climate change, sustainability, food security, feminism, harm to animals, personal health, and public health lead contemporary Stoics to condemn the meat industrial complex, debunk carnism, and select low input, plant-based foods.

Assume we could someday create artificial creatures with intelligence comparable to our own. Could it be ethical use them as unpaid labor? There is very little philosophical literature on this topic, but the consensus so far has been that such robot servitude would merely be a new form of slavery. Against this consensus I defend the permissibility of robot servitude, and in particular the controversial case of designing robots so that they want to serve human ends. A typical objection to (...) this case draws an analogy to the genetic engineering of humans: if designing eager robot servants is permissible, it should also be permissible to design eager human servants. Few ethical views can easily explain even the wrongness of such human engineering, however, and those few explanations that are available break the analogy with engineering robots. The case turns out to be illustrative of profound problems in the field of population ethics. (shrink)

One of the most important recent developments in the study of concepts has been the resurgence of interest in nativist accounts of the human conceptual system. However, many theorists suppose that a key feature of neural organization—the brain’s plasticity—undermines the nativist approach to concept acquisition. We argue that, on the contrary, not only does the brain’s plasticity fail to undermine concept nativism, but a detailed examination of the neurological evidence actually provides powerful support for concept nativism.

Levy (2021 Levy, N. (2021). Bad beliefs: Why they happen to good people. Oxford University Press.[Crossref], [Google Scholar]) argues that bad beliefs predominately stem from automatic (albeit rational) updating in response to testimonial evidence. To counteract such beliefs, then, we should focus on ridding our epistemic environments of misleading testimony. This paper responds as follows. First, I argue that the suite of automatic processes related to bad beliefs extends well beyond the deference-based processes that Levy identifies. Second, I push back (...) against Levy’s claim that bad beliefs stem from wholly rational processes, suggesting that, in many cases, such processes are better characterized as arational. Finally, I note that Levy is too quick to dismiss the role that individuals can play in cleaning up their own epistemic environments, and I suggest one route through which this is possible. (shrink)

The free energy principle is notoriously difficult to understand. In this paper, we relate the principle to a framework that philosophers of biology are familiar with: Ruth Millikan’s teleosemantics. We argue that: systems that minimise free energy are systems with a proper function; and Karl Friston’s notion of implicit modelling can be understood in terms of Millikan’s notion of mapping relations. Our analysis reveals some surprising formal similarities between the two frameworks, and suggests interesting lines of future research. We hope (...) this will aid further philosophical evaluation of the free energy principle. (shrink)

An overview of the ancient philosophers and their philosophical system (divided into the fields of logic, physics, and ethics) comprising the living, organic, enduring, and evolving body of interrelated ideas identifiable as the Stoic perspective.

To reconcile true claims of de re necessity with the supposedly contingent existence of the concrete objects those claims are typically about, Kripkean essentialists invoke weak necessity. The claim that a is necessarily F is held to be equivalent to the claim that necessarily, if a exists then a is F. This strategy faces a barrage of serious objections a proper subset of which shows that the strategy fails to achieve its intended purpose. Relief can be provided via recourse to (...) a markedly non-Kripkean version of essentialism.1. (shrink)

Neo-Fregean logicists claim that Hume’s Principle (HP) may be taken as an implicit definition of cardinal number, true simply by fiat. A long-standing problem for neo-Fregean logicism is that HP is not deductively conservative over pure axiomatic second-order logic. This seems to preclude HP from being true by fiat. In this paper, we study Richard Kimberly Heck’s Two-Sorted Frege Arithmetic (2FA), a variation on HP which has been thought to be deductively conservative over second-order logic. We show that it isn’t. (...) In fact, 2FA is not conservative over n-th order logic, for all $n \geq 2$. It follows that in the usual one-sorted setting, HP is not deductively Field-conservative over second- or higher-order logic. (shrink)

Epistemic two-dimensional semantics, advocated by Chalmers and Jackson, among others, aims to restore the link between necessity and a priority seemingly broken by Kripke, by showing how armchair access to semantic intensions provides a basis for knowledge of necessary a posteriori truths. The most compelling objections to E2D are that, for one or other reason, the requisite intensions are not accessible from the armchair. As we substantiate here, existing versions of E2D are indeed subject to such access-based objections. But, we (...) moreover argue, the difficulty lies not with E2D but with the typically presupposed conceiving-based epistemology of intensions. Freed from that epistemology, and given the right alternative—one where inference to the best explanation provides the operative guide to intensions—E2D can meet access-based objections, and fulfill its promise of restoring the desirable link between necessity and a priority. This result serves as a central application of Biggs and Wilson, according to which abduction is an a priori mode of inference. (shrink)

In Part One of Religion within the Bounds of Bare Reason, Kant repeatedly refers to a “proof” that human nature has a necessary and universal “evil propensity,” but he provides only obscure hints at its location. Interpreters have failed to identify such an argument in Part One. After examining relevant passages, summarizing recent attempts to reconstruct the argument, and explaining why these do not meet Kant's stated needs, I argue that the elusive proof must have a transcendental form (called quasi‐transcendental (...) because Kant never uses “transcendental” in Religion). With deceptive simplicity, the section titles of Part One, viewed as components in an architechtonic system of religion, constitute steps in just such a proof. (shrink)

Leibniz argues that there must be a fundamental level of simple substances because composites borrow their reality from their constituents and not all reality can be borrowed. I contend that the underlying logic of this ‘borrowed reality argument’ has been misunderstood, particularly the rationale for the key premise that not all reality can be borrowed. Contrary to what has been suggested, the rationale turns neither on the alleged viciousness of an unending regress of reality borrowers nor on the Principle of (...) Sufficient Reason, but on the idea that composites are phenomena and thus can be real only insofar as they have a foundation in substances, from which they directly ‘borrow’ their reality. The claim that composites are phenomena rests in turn on Leibniz's conceptualism about relations. So understood, what initially looked like a disappointingly simple argument for simples turns out to be a rather rich and sophisticated one. (shrink)

After coining the term “philopsychy” to describe a “soul-loving” approach to philosophical practice, especially when it welcomes a creative synthesis of philosophy and psychology, this article identifies a system of geometrical figures (or “maps”) that can be used to stimulate reflection on various types of perspectival differences. The maps are part of the author’s previously established mapping methodology, known as the Geometry of Logic. As an illustration of how philosophy can influence the development of psychology, Immanuel Kant’s table of twelve (...) categories and Carl Jung’s theory of psychological types are shown to share a common logical structure. Just as Kant proposes four basic categories, each expressed in terms of three subordinate categories, Jung proposes four basic personality functions, each having three possible manifestations. The concluding section presents four scenarios illustrating how such maps can be used in philosophical counseling sessions to stimulate philopsychic insight. (shrink)

Kant’s enigmatic term, “Gesinnung”, baffles many readers of Religion within the Bounds of Bare Reason. Detailed analysis of Kant’s theory of Gesinnung, covering all 169 occurrences of cognate words in Religion, clarifies its role in his theories of both general moral decision-making and specifically religious conversion. Whereas the convention of translating “Gesinnung” as “disposition” reinforces a tendency to interpret key Kantian theories metaphysically, and Pluhar’s translation as “attitude” has psychological connotations, this study demonstrates that Kantian Gesinnung is volitional, referring to (...) a person’s principle-based choice to live a certain way. Interpreted as principled “conviction”, Kantian Gesinnung is a religiously-manifested, moral form of Überzeugung (“convincing”). (shrink)

Kant’s pre-1770 philosophy responded to the mind-body problem by applying a theory of “physical influx”. His encounter with Swedenborg’s mysticism, however, left him disillusioned with any dualist solution to Descartes’ problem. One of the major goals of the Critical philosophy was to provide a completely new solution to the mind-body problem. Kant’s new solution is “perspectival” in the sense that all Critical theories are perspectival: it acknowledges a deep truth in both of the controversy’s extremes (i.e., what we might nowadays (...) call eliminative materialism and an absolutely ideal folk psychology), by viewing both as ways of considering the issue, rather than as the only correct approach. Once we take into account its perspectival character, a new way of understanding Kant’s philosophy of mind emerges. The mind is no longer separate from the body, but is a manifestation of it, viewed from another (specifically human, rational) perspective. Kant’s transcendental conditions of knowledge (spatio-temporal intuition, categorial conception, and principled schematization) do not portray the mind as somehow creating the physical world; rather, they imply the opposite, that knowledge of objects is necessarily structured by a set of unconscious assumptions about the physical world. Our pre-conscious (or pre-mental, in Descartes’ sense of “mental”) encounter with an assumed spatio-temporal, causal nexus is entirely physical. A reincarnated Kant’s solution to today’s mind-body problem would be: eliminative materialism is good science; but only the “explanatory idealist” can consistently be an eliminative materialist. Philosophically, multiple perspectives are necessary in order to understand anything we say or do. (shrink)

This paper argues that the innovation of an ordering source parameter in the standard Lewis-Kratzer semantics for modals was a mistake, at least for English auxiliaries like ‘ought’, and that a simpler dyadic semantics (as proposed in my earlier work) provides a superior account of normative uses of modals. I programmatically investigate problems arising from (i) instrumental conditionals, (ii) gradability and “weak necessity”, (iii) information-sensitivity, and (iv) conflicts, and show how the simpler semantics provides intuitive solutions given three basic moves: (...) (1) an end-relational analysis of normative modality, (2) a “most” analysis of “weak necessity”, and (3) well-motivated appeals to pragmatics. I conclude with metasemantic observations about the desiderata for a semantics for ‘ought’. (shrink)

This article examines the plausibility of regarding altruism in terms of universal friendship. Section 1 frames the question around Aristotle’s ground-breaking philosophy of friendship. For Aristotle, most friendships exist for selfish reasons, motivated by a desire either for pleasure(playmates) or profit (workmates); relatively few friendships are genuine, being motivated by a desire for shared virtue (soulmates). In contrast to this negative answer to the main question, Section 2 examines a possible religious basis for affirming altruism, arising out of the so-called (...) “love command” – the biblical maxim that we ought to love others as we love ourselves. Many theologians have cited this maxim to justify altruism, with some (such as Aelred of Rievaulx) explicitly portraying it as a form of friendship. Section 3 examines Kant’s view of friendship, arguing that, although at first his position seems disappointingly limited, it actually captures the essence of the only possible form of friendship that could be regarded as a universal ideal without imposing unrealistic expectations onto friends. The article concludes in section 4 by offering a new, Kant-inspired interpretation of Jesus’ parable of the GoodSamaritan: Jesus’ appeal to the love command does enjoin friendship, but not as altruism; rather, love requires a selective form of friendship that is closer to Kant’s position.

This second part of a two-part series exploring implications of the natural differences between the sexes for the cultural evolution of marriage considers how the institution of marriage might evolve, if Kant’s reasons for defending monogamy are extended and applied to a future culture. After summarizing the philosophical framework for making cross-cultural ethical assessments that was introduced in Part I and then explaining Kant’s portrayal of marriage as an antidote to the objectifying tendencies of sex, I summarize Kant’s reasons for (...) rejecting polygamy and for viewing monogamy as the only ethically acceptable form of marriage. Finally, I argue that if we apply Kantian principles to the real situation of marriage in many modern cultures, and if we wish to maintain a legitimate place for marriage in the future evolution of human culture, then the future evolution of marriage laws must recognize polyfidelity (i.e., plural marriages for both men and women) as being just as legitimate as monogamy.

This first part of a two-part series exploring implications of the natural differences between the sexes for the cultural evolution of marriage assesses whether Kant should be condemned as a sexist due to his various offensive claims about women. Being antithetical to modern-day assumptions regarding the equality of the sexes, Kant’s views seem to contradict his own egalitarian ethics. A philosophical framework for making cross-cultural ethical assessments requires one to assess those in other cultures by their own ethical standards. Sexism (...) is inappropriate if it exhibits or reinforces a tendency to dominate the opposite sex. Kant’s theory of marriage, by contrast, illustrates how sexism can be egalitarian: given the natural differences between the sexes, different roles and cultural norms help to ensure that females and males are equal. Judged by the standards of his own day and in the context of his philosophical system, Kant’s sexism is not ethically inappropriate. (shrink)

We introduce the predictive processing account of body representation, according to which body representation emerges via a domain-general scheme of (long-term) prediction error minimisation. We contrast this account against one where body representation is underpinned by domain-specific systems, whose exclusive function is to track the body. We illustrate how the predictive processing account offers considerable advantages in explaining various empirical findings, and we draw out some implications for body representation research.

The Roman imperial Stoics were familiar with exile. I argue that the Stoics’ view of being a refugee differed sharply from their view of what is owed to refugees. A Stoic adopts the perspective of a cosmopolitēs, a ‘citizen of the world’, a rational being everywhere at home in the universe. Virtue can be cultivated and practiced in any locale, so being a refugee is an ‘indifferent’ that poses no obstacle to happiness. But other people are our fellow cosmic citizens (...) regardless of their language, race, ethnicity, customs, or country of origin. Our natural affinity and shared sociability with all people require us to help refugees and embrace them as welcome neighbors. Failure to do so violates our common reason, justice, and the gods’ cosmic law. (shrink)

This article begins with an overview of the fourfold epistemological framework that arises out of Kant’s distinctions between analyticity and syntheticity and between apriority and aposteriority. I challenge Kant’s claim that the fourth classification, analytic aposteriority, is empty. In reviewing three articles written during the third quarter of the twentieth century that also defend analytic aposteriority, I identify promising insights suggested by Benardete (1958). I then present overviews of two 1987 articles wherein I defend analytic aposteriority, first as a classification (...) highlighting the epistemological status of several crucial (and easily misunderstood) features of Kant’s own philosophy, and second as a way of expressing some of Kripke’s claims about naming in more authentically Kantian terminology. The paper concludes with suggestions of several other important philosophical developments that also make advances precisely insofar as they expound the nature and implications of the epistemological classification that Kant assumed to be empty.

Aside from bioethics, the main theme of Ronald Green's lifework has been an exploration of the relation between religion and morality, with special emphasis on the philosophies of Immanuel Kant and Søren Kierkegaard. This essay summarizes and assesses his work on this theme by examining, in turn, four of his relevant books. Religious Reason (1978) introduced a new method of comparative religion based on Kant's model of a rational religion. Religion and Moral Reason (1988) expanded on this project, clarifying that (...) religious traditions cannot be reduced to their moral grounding. Kierkegaard and Kant: The Hidden Debt (1992) offered bold new evidence that Kant, not Hegel, was the philosopher whose ideas primarily shaped Kierkegaard's overtly religious philosophy ; both philosophers focused on the problem of how to understand the relation between moral reasoning and historical religion. And Kant and Kierkegaard on Time and Eternity (2011) republished ten essays that explore various aspects of this theme in greater depth. I argue that throughout these works Green defends a " paradox of inwardness " : principles or ideals that are by their nature essentially inward end up requiring outward manifestation in order to be confirmed or fully justified as real.

In his Quadratura, Paul of Venice considers a sophism involving time and tense which appears to show that there is a valid inference which is also invalid. His argument runs as follows: consider this inference concerning some proposition A: A will signify only that everything true will be false, so A will be false. Call this inference B. Then B is valid because the opposite of its conclusion is incompatible with its premise. In accordance with the standard doctrine of ampliation, (...) Paul takes A to be equivalent to 'Everything that is or will be true will be false'. But he proceeds to argue that it is possible that B's premise ('A will signify only that everything true will be false') could be true and its conclusion false, so B is not only valid but also invalid. Thus A and B are the basis of an insoluble. In his Logica Parva, a self-confessedly elementary text aimed at students and not necessarily representing his own view, and in the Quadratura, Paul follows the solution found in the Logica Oxoniensis, which posits an implicit assertion of its own truth in insolubles like B. However, in the treatise on insolubles in his Logica Magna, Paul develops and endorses Swyneshed's solution, which stood out against this ''multiple-meanings'' approach in offering a solution that took insolubles at face value, meaning no more than is explicit in what they say. On this account, insolubles imply their own falsity, and that is why, in so falsifying themselves, they are false. We consider how both types of solution apply to B and how they complement each other. On both, B is valid. But on one (following Swyneshed), B has true premises and false conclusion, and contradictories can be false together; on the other (following the Logica Oxoniensis), the counterexample is rejected.

This fourth article in a six-part series correlating Kant’s philosophy with the Yijing begins by summarizing the foregoing articles: both Kant and the Yijing’s 64 hexagrams (gua) employ “architectonic” reasoning to form a four-level system with 0+4+12+(4x12) elements, the fourth level’s four sets of 12 correlating to Kant’s model of four university “faculties”. This article explores the second twelvefold set, the law faculty. The “idea of reason” guiding this wing of the comparative analysis is immortality. Three of Kant’s “quaternities” correspond (...) to three sets of four gua in the Yijing: the fourfold nature of the soul in rational psychology (as substantial, simple, unified, spatially related) corresponds to gua 47, 6, 58, 10, respectively; the three “Definitive Articles” and fourth, “Secret Article”, in Perpetual Peace correspond to gua 16, 35,51, 21; and the four objective relations of law to duty in Metaphysics of Morals correspond to gua 45, 12, 17, 25.

More than a century before Anscombe counseled us to jettison concepts such as that of the moral ought, or moral law, Schopenhauer mounted a vigorous attack on such prescriptive moral concepts, particularly as found in Kant. In this chapter I consider the four objections that constitute this attack. According to the first, Kant begs the question by merely assuming that ethics has a prescriptive or legislative-imperative form, when a purely descriptive-explanatory conception such as Schopenhauer’s also presents itself as a possibility. (...) According to the second, Kant’s purportedly philosophical ethics is in fact a theological ethics in disguise, because the moral ought and its prescriptive cousins presuppose a divine lawgiver. According to the third, Kant’s conceptions of the moral law as a law of freedom, and of moral imperatives as categorical or unconditioned, involve him in contradictions. Finally, Schopenhauer objects that there can be no such thing as a moral ought because a binding ought or law must be understood to operate through appeals to self-interest, which stands in opposition to morality. I contend that these last three objections are sound and that the fourth in particular succeeds in confuting the prescriptivist conception of morality. (shrink)

This paper defends the view that normative force depends on desire, by sketching an Argument from Voluntary Response which attempts to establish this dependence by appeal to the autonomous character of our experience of normative authority, and the voluntary character of our responses to it. I first offer an account of desiring as mentally aiming intrinsically at some end. I then argue that behaviour is only voluntary if it results from such aiming; hence all voluntary behaviour is produced by desire. (...) Full-blooded responses to normativity are voluntary actions: motivation to act arises voluntarily from perception of reasons to act. This fits the desire-based model of normativity but not its rivals (in particular I take as a foil Stephen Darwall's discussion of Roberta). However this argument concludes merely that our responses to normativity are desire-based. I end with observations about how we can bridge the gap from the nature of response to normativity to the nature of normativity itself. (shrink)

Instead of interpreting Berkeley in terms of the standard way of relating him to Descartes, Malebranche, and Locke, I suggest we consider relating him to other figures (e.g., Stoics, Ramists, Suarez, Spinoza, Leibniz). This allows us to integrate his published and unpublished work, and reveals how his philosophic and non-philosophic work are much more aligned with one another. I indicate how his (1) theory of powers, (2) "bundle theory" of the mind, and (3) doctrine of "innate ideas" are understood in (...) a way significantly different from that found in the standard account.

Mental causes are threatened from two directions: from below, since they would appear to be screened off by lower-order, e.g., neural states; and from within, since they would also appear to be screened off by intrinsic, e.g., syntactical states. A principle needed to parry the first threat -causes should be proportional to their effects- appears to leave us open to the second; for why should unneeded extrinsic detail be any less offensive to proportionality than excess microstructure? I say that the (...) second threat relies on a perversion of proportionality that would lay waste to all causal relations. (shrink)

This article is a rebuttal to Robert G. Cavin and Carlos A. Colombetti’s article, “Assessing the Resurrection Hypothesis: Problems with Craig’s Inference to the Best Explanation,” which argues that the Standard Model of current particle physics entails that non-physical things (like a supernatural God or a supernaturally resurrected body) can have no causal contact with the physical universe. As such, they argue that William Lane Craig’s resurrection hypothesis is not only incompatible with the notion of Jesus physically appearing to the (...) disciples, but the resurrection hypothesis is significantly limited in both its explanatory scope and explanatory power. This article seeks to demonstrate why their use of the Standard Model does not logically entail a rejection of the physical resurrection of Jesus when considering the scope and limitations of science itself.

I set up a dilemma, concerning metaphysical modality de re, for the essentialist opponent of a ‘two senses’ view of necessity. I focus specifically on Frank Jackson's two-dimensional account in his From Metaphysics to Ethics (Oxford: Oxford University Press, 1998). I set out the background to Jackson's conception of conceptual analysis and his rejection of a two senses view. I proceed to outline two purportedly objective (as opposed to epistemic) differences between metaphysical and logical necessity. I conclude that since one (...) of these differences must hold and since each requires the adoption of a two senses view of necessity, essentialism is not consistent with the rejection of a two senses view.

I examine the (mediated) correspondence between Spinoza and Robert Boyle concerning the latter’s account of fluidity and his experiments on reconstitution of niter in the light of the epistemology and doctrine of method contained in the Treatise on the Emendation of the Intellect. I argue that both the Treatise and the correspondence reveal that for Spinoza, the proper method of science is not experimental, and that he accepted a powerful under-determination thesis. I argue that, in contrast to modern versions, Spinoza’s (...) form of naturalism was a highly rationalist and anti-empirical one. I conclude with a brief account of the value of experience and experimentation for Spinoza’s scientific method. (shrink)

Among epistemologists and philosophers of science, one often hears that someone with understanding is able to “see” or “grasp” how the elements of a subject “cohere” or “fit together”—but just what is involved in the seeing or the grasping is usually left to the imagination. I argue that the most productive way to make progress on this issue is by first identifying the kind of explanation-seeking why-questions that drive the search for understanding in the first place. In particular, I suggest (...) that if we can get a good grip on why a situation stands in need of explanation for us in the first place, then we will in turn be in a good position to determine how we might satisfy that need. In this respect, I argue that a situation stands in need of explanation for us, and therefore inspires our why-questions, in virtue of our sense that there are various ways that we think the situation might have been. If a situation stands in need of explanation for this reason, moreover, then in order to satisfy the need for explanation our objective will be to identify what the difference between these alternatives depends on. To say only this much still leaves a great deal underdetermined, however, for we might “identify” what the difference depends on in a number of different ways: for example, by having a true belief about what the difference depends on, by knowing this on the basis of testimony, and so on. What is distinctive about the state of understanding, I suggest, is the particular way in which we identify what the difference depends on: namely, by grasping what the difference depends on. I explore at length what exactly this grasping amounts to. (shrink)

Leibniz claims that Berkeley “wrongly or at least pointlessly rejects abstract ideas”. What he fails to realize, however, is that some of his own core views commit him to essentially the same stance. His belief that this is the best (and thus most harmonious) possible world, which itself stems from his Principle of Sufficient Reason, leads him to infer that mind and body must perfectly represent or ‘express’ one another. In the case of abstract thoughts he admits that this can (...) happen only in virtue of thinking of some image that, being essentially a mental copy of a brain state, expresses (and is expressed by) that state. But here he faces a problem. In order for a thought to be genuinely abstract, its representational content must differ from that of any mental image, since the latter can represent only particular things. In that case, however, an exact correspondence between the accompanying mental image and the brain state would not suffice to establish a perfect harmony between mind and body. Even on Leibniz’s own principles, then, it appears that Berkeley was right to dismiss abstract ideas. (shrink)

Philosophers often suggest that their theories of free will are supported by our phenomenology. Just as their theories conflict, their descriptions of the phenomenology of free will often conflict as well. We suggest that this should motivate an effort to study the phenomenology of free will in a more systematic way that goes beyond merely the introspective reports of the philosophers themselves. After presenting three disputes about the phenomenology of free will, we survey the (limited) psychological research on the experiences (...) relevant to the philosophical debates and then describe some pilot studies of our own with the aim of encouraging further research. The data seem to support compatibilist descriptions of the phenomenology more than libertarian descriptions. We conclude that the burden is on libertarians to find empirical support for their more demanding metaphysical theories with their more controversial phenomenological claims. (shrink)
