It is now common to explain some of incidental perception’s features by means of a different capacity, called phantasia . Phantasia , usually translated as ‘imagination,’ is thought to explain how incidental perception can be false and representational by being a constitutive part of perception. Through a close reading of De Anima 3.3, 428b10–29a9, I argue against this and for perception first : phantasia is always a product of perception, from which it initially inherits all its characteristics. No feature of perception is explained directly by phantasia , and phantasia is never a part of perception. Phantasia is not imagination or representation, as many have thought, but perception-like appearance. Aristotle thus recognizes alongside three different types of perception three different types of perception-like appearance.

Although Aristotle’s Metaphysics received much attention in the nineteenth and the twentieth centuries, scholars and historians of science were not particularly interested in clarifying the aim of Aristotle’s appeal to astronomy in Λ 8. Read with monotheistic prejudices, this chapter was quickly abandoned by Aristotelian scholars as a gratuitous insertion, which downgrades Aristotle’s God for the sake of some supplementary principles, whose existence was dictated by celestial mechanics. On the other hand, historians of astronomy read the astronomical excursus as providing a picture of Aristotle as an able astronomer, who made an important contribution to the theory of concentric celestial spheres of Eudoxus and Callippus by adding the counteracting spheres. The present article argues (a) that Aristotle purposefully turned to astronomy as the only mathematical science whose objects were correlative to the immaterial first substances or gods, the number of which had to be precisely determined by his own project of first philosophy; and (b) that he had no aspiration of improving the astronomical theory of his peers, contrary to an interpretation that first emerged with the Peripatetic exegete Sosigenes in the second century A.D.

There is a debate about whether particular properties are for Aristotle non-recurrent and trope-like individuals or recurrent universals. I argue that Physics  I.7 provides evidence that he took non-substantial particulars to be neither; they are instead non-recurrent modes. Physics  I.7 also helps show why this matters. Particular properties must be individual modes in order for Aristotle to preserve three key philosophical commitments: that objects of ordinary experience are primary substances, that primary substances undergo genuine change, and that primary substances are ontologically fundamental.

This paper is dedicated to feelings ( pathē ) as criteria of truth and criteria of choice and avoidance in Epicureanism. The first section reviews two features of the other two Epicurean criteria of truth, perceptions and preconceptions: their non-rational and evident character. The second section extends the account to feelings, showing how, on the basis of their non-rational and evident character, feelings can be used to gain insights. The third section of the paper finally turns to feelings as criteria of choice and avoidance. It examines some neglected textual evidence that shows that perceptions and feelings are closely connected to each other, that is, that Epicurean feelings are defined as perceptions and observances of themselves, shedding some new light on the joint role of feelings and perceptions in choices and avoidances.

This paper aims to explain the distinction between syllogisms and subsyllogisms in Stoic logic. Subsyllogisms replace at least one premise in a syllogism with a premise that is, according to Galen and Alexander, equipollent to the respective syllogistic premise. This equipollence is not synonymy of meaning between two linguistic expressions, but obtains between two propositions when they are true or false by the same standard. Subsyllogistic premises are simple propositions that are equipollent to the non-simple premises of the respective syllogisms. For subsyllogistic premises that replace syllogistic premises consist of predicates combining with cases rather than of connectives or negations governing propositions. Because of this difference in their premises, subsyllogisms have a different logical form than syllogisms and are not formally valid.

Commentators generally agree that Foucher presumes the resemblance theory of representation and uses it to substantiate external world skepticism. In this paper, I challenge this picture. First, I argue that he does not assume that representation is reducible to, or even just works through, resemblance between representation and object. Indeed, his functional-similarity theory primarily appeals to resemblance between the respective effects the representation and the object (would) have on our minds. I also propose that his argument for the resemblance-requirement of representation depends on the causal likeness principle, and clarify its role in Foucher’s theory. Second, I show that his main interest lies with representation in the sense of truthfully making the object present. Accordingly, when Foucher concludes that we can only represent our own ideas, he merely means that our ideas reveal the ways objects affect us through our senses, as opposed to how they are in themselves.

Few fates seem worse than living without cause for hope . Yet what is it to have a cause for hope? And how is it related to having hope? Although these questions have received relatively little philosophical attention, I argue that Kant advances a rationalist account of hope that addresses them. My central thesis has two parts. First, hope is a rational attitude for Kant; certain rational conditions are needed to differentiate hope from other desiderative attitudes (such as mere wishing or fantasizing ). Second, these rational conditions involve causal inferences made by the hoping agent. To hope, an agent must make certain inferences about the cause of her desire and the cause of her belief that the object of her desire is possible. In short, to hope requires an agent to take herself to have a cause for hope .

In Matter and Memory , Bergson identifies a problem with perception and resolves it by arguing that matter is an aggregate of images. However, it is unclear whether and how Bergson justifies this thesis, and interpreters differ considerably on this question. This paper formulates and analyzes Bergson’s arguments for this thesis in Chapter 1 of Matter and Memory . Bergson presents five arguments, some of which echo arguments in early modern philosophy. They jointly compose a substantive, well-structured defense of his thesis. This paper also illuminates an aspect of Bergson’s method that departs from his famous reliance on intuition and is grounded in his conception of the clarity required in philosophy.

This essay explores Wittgenstein’s encounter with Stumpf’s work in Tone Psychology during a rarely studied period in Wittgenstein’s early career when he worked as a researcher in Myers’s laboratory for experimental psychology in Cambridge. I argue that Stumpf’s emphasis on the notion of musicality as the ability to characterize what is ‘musical’ about music troubled Wittgenstein’s initial formulation of his career-long adherence to the comparison between language and music. In the Tractatus the importance of internal projective relations far exceeds that of arbitrariness in language. This results in the curious elision of musicality in the Tractatus , as shown in his gramophone analogy. The acknowledgment of the enormous complexity pertaining to the facts of human life remained underdeveloped in Wittgenstein’s philosophy until the anthropological turn in his middle-period. Only then do we see the blooming of the language-as-music simile and its eventual impact on Wittgenstein’s later philosophy.

In this article I examine the dispute between F. H. Bradley and Bertrand Russell concerning the reality of relations . I show that Bradley’s objections to Russell’s view, that there are such things as relations which serve to effect the unity of complex items, were rooted in a methodological approach which Russell did not share. On Bradley’s view, one must be able to offer reductive analyses of the items one postulates in order that commitment to those items be justified. I argue that Russell expressly rejected this methodological principle of Bradley’s, and instead adopted the view that one may justifiably postulate entities if doing so aids in the illumination of mathematical truths. I show that the postulation of relations does, on Russell’s view, serve to provide that illumination. Russell held that the truths of mathematics constitute fixed data, and that philosophical positions may be judged as successful according to the extent that they possess explanatory power with respect to this data. I argue that Bradley’s and Russell’s exchanges in print, as well as in private correspondence, reflect Russell’s awareness of a fundamental difference in methodological approach. I conclude that Russell elected not to answer Bradley’s objections on their own terms, but rather rejected the methodological assumptions from which those objections emerged.
