Modern Empiricists are typically troubled by the two following problems: (1) There is an epistemic gap between experience of individuals and understanding universals such that empiricist accounts of concept formation seem to beg the question. (2) There needs to be an answer to the skeptic who denies that sensory experience warrants our belief in the existence of the material substances that underlie sensible qualities. Although Aristotle’s account of induction is subject to these problems prima facie, his theory of perception, his (...) teleologically driven reliabilism about the senses, and his broader metaphysical views concerning the relation between substance and accident serve to insulate his account of induction from the pitfalls of modern empiricism. The resolution to these problems proposed in this paper allows for a consistent reading of otherwise controversial Aristotelian texts, while recommending a defense of realism about material substance against the claims of the Humean skeptic.

The phrase koine aisthesis appears, as far as I can see, very rarely in Aristotle. There is one definite use of the phrase in the De Anima, at 425a27. The word koine without aisthesis but such that the latter must be supplied may possibly occur at 431b5, but the text is uncertain there, and there is every reason why the word should be deleted from the text. This leaves us with a single occurrence of the phrase koine aisthesis in the (...) De Anima and it is used explicitly to deal with perception of the koina, the so-called common sensibles. Outside the De Anima, the phrase occurs at De Memoria 450a10, and at De Partibus Animalium 686a27, and I think nowhere else. Of these two passages that from the De Memoria is, although somewhat obscure, in line with the De Anima reference; it seems to invoke the common sense for the perception of magnitude, motion and time, and also says that an image is a pathos of the common sense, presumably because an image must be of a magnitude. The De Partibus Animalium passage is somewhat more eccentric. It is concerned with the fact that man is the only animal to walk upright, and associates this with the fact that man can think. This would not be easy if he had much of his body weighing down on him from above, for weight makes unresponsive thought and the common sense- τὴν διάνοιαν καὶ τὴν κοινὴν αἴσθησιν. Whatever be the other curiosities in this passage, the close association of thought and the common sense is itself at first sight rather strange. If any account can be given of it, it is presumably because of the facts adduced in the De Memoria passage, that thinking involves images, and these the koine aisthesis. (shrink)

The taxonomy and analysis of fallacies in Aristotle's Sophistical Refutations pre-date the formal logic of his Prior Analytics A4-6. Of the 64 fully described examples of ?sophistical refutations? which are fallacious because they are only apparently valid, 49 have the wrong number of premisses or the wrong form of premiss or conclusion for analysis by the Prior Analytics theory of the categorical syllogism. The rest Aristotle either frames so that they do not look like categorical syllogisms or analyses in a (...) quite different way than by categorical syllogistic. (shrink)

Aristotle's discussion of perceiving that we perceive has points of contact with two contemporary debates about consciousness: the first over whether consciousness is an intrinsic feature of mental states or a higher-order thought or perception; the second concerning the qualitative nature of experience. In both cases, Aristotle's views cut down the middle of an apparent dichotomy, in a way that does justice to each set of intuitions, while avoiding their attendant difficulties. With regard to the first issue?the primary focus of (...) this paper?he argues that consciousness is both intrinsic and higher-order, due to its reflexive nature. This, in turn, has consequences for the second issue, where again Aristotle seeks out the middle ground. He is committed against qualia in any strong sense of the term. Yet he also holds that the phenomenal quality of experience is not exhausted by its representational content. (shrink)

HOW WE BECOME AWARE OF PHYSICAL OBJECTS OVER AND ABOVE THE PERCEPTUAL ACTS OF SEEING COLOR, SHAPES AND HEARING SOUNDS, ETC., IS A QUESTION THAT HAS OCCUPIED MANY CONTEMPORARY PHILOSOPHERS OF SENSE-PERCEPTION. DID ARISTOTLE EVER FACE THIS PROBLEM, AND IF HE DID, HOW DID HE DEAL WITH IT? THIS ARTICLE DISCUSSES THIS QUESTION AND CONCLUDES THAT THE ANSWER TO IT CAN BE FOUND "DE INSOMNIAS" IN ARISTOTLE'S DISCUSSION OF DREAMS AND ILLUSIONS. THERE IS AN ACT AFFIRMATION ("PHESIN") CARRIED OUT BY (...) THE CONTROLLING AND DISCRIMINATING SENSE ("TO KURION KAI TO EPIKRINON") WHICH DOES THIS. "FOR, SPEAKING GENERALLY, THE CONTROLLING POWER ("ERXE") AFFIRMS ("PHESIN") THE REPORT GIVEN BY EACH SENSE UNLESS SOME MORE AUTHORITATIVE POWER CONTRADICTS IT.". (shrink)

The paper discusses the active part in the process of perceiving, usually expressed by the Greek word krinein. It is argued that krinein in one of its uses means "to judge" in the sense of judging a case, i. e. deciding it. It is not used for making statements. A second meaning of the Greek word is that of discerning or discriminating, and it is this meaning that plays a central part in Aristotle's theory of perception.
