In De Anima II.6, Aristotle divides the objects of perception into three kinds: “special perceptibles" (idia aisthêta) such as colours, sounds and flavours, which can be perceived in their own right by only one sense; “common perceptibles" (koina aisthêta) such as shapes, sizes and movements, which can be perceived in their own right by multiple senses; and “incidental perceptibles,” such as the son of Diares, which can be perceived only “incidentally” (kata sumbebêkos). In this paper, I examine this division of (...) perceptibles and consider what it amounts to. First, I argue that Aristotle’s distinction between perceiving something in its own right (kath' hauto) and perceiving it incidentally marks a causal distinction: what is perceived in its own right causes perception as such, whereas what is perceived incidentally coincides with what is perceived in its own right. Second, I argue that for Aristotle special perceptibles, unlike common perceptibles, belong to homogeneous bodies on account of their chemical composition. Finally, I explain the primacy Aristotle assigns to special perceptibles and his claim that perception of them alone is free from error. I conclude with some brief remarks on Aristotle and the primary/secondary quality distinction. (shrink)

Like dreaming, hallucination has been a formative trope for modern philosophy. The vivid, often tragic, breakdown in the mind’s apparent capacity to disclose reality has long served to support a paradoxical philosophical picture of sensory experience. This picture, which of late has shaped the paradigmatic empirical understanding the senses, displays sensory acts as already complete without the external world; complete in that the direct objects even of veridical sensory acts do not transcend what we could anyway hallucinate. Hallucination is thus (...) the mother of Representationalism, which insists that it is mental intermediaries that make other.. (shrink)

A while ago I pulled the short straw, and became chair of my department. One nice part of the job is to praise people I work with, which I can do sincerely because they are very praiseworthy. I also have to read a lot of praise by others; the familiar things—project evaluations, letters of recommendation, promotion dossiers, and so on and so forth. As a result, I have learnt to attend to praise a little more closely.

Johnston presents an argument for a form of immortality that divests the notion of any supernatural elements. The book is packed with illuminating philosophical reflection on the question of what we are, and what it is for us to persist over time.

In this book, Mark Johnston argues that God needs to be saved not only from the distortions of the "undergraduate atheists" but, more importantly, from the idolatrous tendencies of religion itself. Each monotheistic religion has its characteristic ways of domesticating True Divinity, of taming God's demands so that they do not radically threaten our self-love and false righteousness. Turning the monotheistic critique of idolatry on the monotheisms themselves, Johnston shows that much in these traditions must be condemned as false (...) and spiritually debilitating. A central claim of the book is that supernaturalism is idolatry. If this is right, everything changes; we cannot place our salvation in jeopardy by tying it essentially to the supernatural cosmologies of the ancient Near East. Remarkably, Johnston rehabilitates the ideas of the Fall and of salvation within a naturalistic framework; he then presents a conception of God that both resists idolatry and is wholly consistent with the deliverances of the natural sciences. Princeton University Press is publishing Saving God in conjunction with Johnston's forthcoming book Surviving Death, which takes up the crux of supernaturalist belief, namely, the belief in life after death.

This study employs a pretest-posttest experimental design to extend recent research pertaining to the effects of teaching business ethics material. Results on a variety of perceptual and attitudinal measures are compared across three groups of students — one which discussed the ethicality of brief business situations (the business scenario discussion approach), one which was given a more philosophically oriented lecture (the philosophical lecture approach), and a third group which received no specific lecture or discussion pertaining to business ethics. Results showed (...) some significant differences across the three groups and demonstrated that for a single lecture, the method used to teach ethics can differentially impact ethical attitudes and perceptions. Various demographic and background variables did not moderate the relationship between the teaching method and the dependent variables, but the sex of the student was strongly associated with the ethical attitude and perception measures.

Aristotle sometimes claims that the perception of special perceptibles by their proper sense is unerring. This claim is striking, since it might seem that we quite often misperceive things like colours, sounds and smells. Aristotle also claims that the perception of common perceptibles is more prone to error than the perception of special perceptibles. This is puzzling in its own right, and also places constraints on the interpretation of. I argue that reading Alexander of Aphrodisias on perceptual error can help (...) to make good sense of both of Aristotle’s claims. (shrink)

The world-view to which the long arc of modern philosophy since Descartes bends is Materialism With A Bad Conscience, a Materialism continually bedeviled by the need to deal with apparently irreducible mental items. I believe this world-view to be the offspring of an introjective error; in effect, the mentalization of sensible form, finality and value. Hence the characteristic modernist accusation is that when we take sensible form, finality and value to be genuine features of the manifest we are thereby "projecting" (...) aspects of our mental life onto an environment devoid of these features. David Hume went furthest in this Projectivist direction arguing that indeed even the very notion of an efficient cause was a projection of our habitual expectations that the regularly observed consequences of certain classes of events would continue. So far from these expectations constituting a practical knowledge of efficient causes, acquired over immense periods of time in the life of our species as it adapted to and with its complex causal environment, those expectations are merely appearances which we mistake for a mind-independent relation among the things themselves. Thus the manifest is traded in for the "manifest image of the world," an image interposed between a subject and deracinated environment. (shrink)

God’s creative act, if genuinely free, would ground the existence of creatures without necessitating them. Since God is perfectly responsive to reason, his freely creating requires that he have an adequate but non-coercive reason to create. A coercive reason for an act is one that outweighs the reasons for any alternative act, whereas an adequate reason is one that is not outweighed by the reasons in favor of any alternative act. How, in the absence of an offsetting reason not to (...) create, is God’s adequate reason not also a coercive reason, i.e., one that would necessitate creation? Chapter 7 argues that God’s creating and God’s remaining within himself each have to be understood as determinate manners in which God may affirm his own unsurpassable goodness. Cantorian reflections are then deployed to explain how God’s extra, i.e., un-offset, reason to create does not give him more of a reason to create than to not create. Finally, God’s actual reason to create is identified. (shrink)

In this paper, I offer a new solution to the old problem of how best to understand the meaning of the word ‘logos’ in the extant writings of Heraclitus, especially in fragments DK B1, B2 and B50. On the view I defend, Heraclitus was neither using the word in a perfectly ordinary way in these fragments, as some have maintained, nor denoting by it some kind of general principle or law governing change in the cosmos, as many have claimed. Rather, (...) I argue, Heraclitus deliberately traded on the ordinary use of the word in his time (to refer to a written or spoken presentation of things as ‘thus and so’) to denote the world’s constant presentation of itself as ‘thus and so’ to all of us in our experience – a kind of cosmic self-revelation. I show how this captures the sense in which ‘the logos’ is said to be ‘common’ (xunos) and to be the kind of thing most people fail to comprehend even before hearing Heraclitus’ own account, all without detaching Heraclitus’ use of the word from its ordinary contemporary meaning. This interpretation suggests Heraclitus was a thinker more centrally concerned with human (mis)understanding than with speculative cosmology. (shrink)

The sense of smell occupies a peculiar intermediate position within Aristotle's theory of sense perception: odours, like colours and sounds, are perceived at a distance through an external medium of air or water; yet in their nature they are intimately related to flavours, the proper objects of taste, which for Aristotle is a form of touch. In this paper, I examine Aristotle's claims about odour and smell, especially in De Anima II.9 and De Sensu 5, to see what light they (...) shed on his theory of sense perception more generally. In the first half, I argue that neither of the two most influential recent ways of understanding Aristotle's theory of perception can adequately account for what he says about the sense of smell. In the second half, I offer my own positive account, considering and resolving various puzzles raised by Aristotle's claims about the nature of odour and its relation to flavour. Finally, I conclude that Aristotle's discussions of odour and smell suggest a plausible and interesting way of understanding the relationship, on his view, between ordinary, material changes in the sense organs and the activation of the capacity to perceive, considered merely as such.

Aristotle is history’s most famous and influential proponent of the view that there are exactly five senses. But was he entitled to hold this view, given his other commitments? In particular, was he entitled to treat touch as a single sense, given the diversity of its correlated objects? In this paper I argue that Aristotle wished to individuate touch on the basis of its correlated objects, just as he had the other four senses. I also argue, contrary to what is (...) often supposed, that he was well-placed to do so, given his other commitments and views. (shrink)

In this paper I consider two related issues raised by Aristotle 's treatment of hearing and sounds. The first concerns the kinds of changes Aristotle takes to occur, in both perceptual medium and sense organs, when a perceiver hears a sounding object. The second issue concerns Aristotle 's views on the nature and location of the proper objects of auditory perception. I argue that Aristotle 's views on these topics are not what they have sometimes been taken to be, and (...) that when rightly understood they compare favourably in many respects with leading contemporary accounts.

In book 9 of Plato's Republic, Socrates describes the nature and origins of the ‘tyrannical man’, whose soul is said to be ‘like’ a tyrannical city. In this paper, I examine the nature of the ‘government’ that exists within the tyrannical man's soul. I begin by demonstrating the inadequacy of three potentially attractive views sometimes found in the literature on Plato: the view that the tyrannical man's soul is ruled by his ‘lawless’ unnecessary appetites, the view that it is ruled (...) by sexual desire, and the view that it is ruled by a lust for power. I then present my own account. On the view I defend, the tyrannical man's soul is to be understood as ruled by a single, persistent, powerful desire for bodily pleasure: as much as he can get, and however he can get it. Finally, I show how understanding the tyrannical man's soul in the way I recommend helps resolve some commonly expressed concerns about this part of the Republic. I suggest, on this basis, that Plato's procedure in constructing his catalogue o.. (shrink)

In books 8 and 9 of Plato’s Republic, Socrates provides a detailed account of the nature and origins of four main kinds of vice found in political constitutions and in the kinds of people that correspond to them. The third of the four corrupt kinds of person he describes is the ‘democratic man’. In this paper, I ask what ‘rules’ in the democratic man’s soul. It is commonly thought that his soul is ruled in some way by its appetitive part, (...) or by a particular class of appetitive desires. I reject this view, and argue instead that his soul is ruled by a succession of desires of a full range of different kinds. I show how this view helps us better understand Plato’s depiction of corrupt souls in the Republic more generally, and with it his views on the rule of the soul, appetitive desire, and the nature of vice.

In this paper, I consider how each of the four main kinds of corrupt person described in Plato's Republic, Books 8-9, first comes to be. Certain passages in these books can give the impression that each person is able to determine, by a kind of rational choice, the overall government of his/her soul. However, I argue, this impression is mistaken. Upon careful examination, the text of books 8 and 9 overwhelmingly supports an alternative interpretation. According to this view, the eventual (...) government of each person’s soul is decided by a struggle for power occurring within the person, among the soul’s parts, the outcome of which is determined by the relative strength and alignment of the competing parties. If this interpretation is correct, Plato adheres more closely to the city-soul analogy in these passages than has sometimes been thought. The ultimate origins of vice in the soul are also seen to lie squarely in upbringing and education, not in a mistaken choice of life. (shrink)
