Thomas Reid thought of himself as a critic of the representative theory of perception, of what he called the ‘theory of ideas’ or ‘the ideal theory’.2 He had no kind words for that theory: “The theory of ideas, like the Trojan horse, had a specious appearance both of innocence and beauty; but if those philosophers had known that it carried in its belly death and destruction to all science and common sense, they would not have broken down their walls to (...) give it admittance.”3 Many have supposed that his opposition to the representative theory was grounded in his direct realism.4 A direct realist theory of perception holds that perception of external objects is not mediated by any mental entity whose intrinsic character licenses a move from the mental entity to the external object presented in perception. Reid himself, in an oration of 1759, delivered at graduation ceremonies over which he presided as regent and professor of philosophy at King’s College in Aberdeen, said that he did not “understand what need there is of an intermediate object for thought about something to be possible.”5 Hence, if Reid was not a direct realist, philosophers and historians would have to ask whether and to what degree Reid was what he thought himself to be.

It is commonly said of modern philosophy that it introduced a representative theory of perception, a theory that places representative mental items between perceivers and ordinary physical objects. Such a theory, it has been thought, would be a form of indirect realism: we perceive objects only by means of apprehending mental entities that represent them. The moral of the story is that what began with Descartes’s revolution of basing objective truth on subjective certainty ends with Hume’s paroxysms of ambivalence and (...) skepticism in the conclusion of the first book of the..

Thomas Reid's distinction between original and acquired perception is not merely metaphysical; it has psychological and phenomenological stories to tell. Psychologically, acquired perception provides increased sensitivity to features in the environment. Phenomenologically, Reid's theory resists the notion that original perception is exhaustive of perceptual experience. James Van Cleve has argued that most cases of acquired perception do not count as perception and so do not pose a threat to Reid's direct realism. I argue that acquired perception is genuine perception and (...) as direct as original perception. Perception is grounded in a productive and developing relationship between the mind and world.

: Some critics find that Thomas Reid thinks the mind especially problematic, "hid in impenetrable darkness". I disagree. Reid does not hold that mind, more than body, resists explanation by the new science. The physical sciences have made great progress because they were transformed by the Newtonian revolution, and the key transformation was to stop looking for causes. Reid's harsh words are a call for methodological reform, consonant with his lifelong pursuit of a science of mind and also with his (...) frequent (though overlooked) optimism about such a science.

Thomas Reid draws a distinction between the social and solitary operations of mind—acts of mind that require other intelligent beings versus those that may performed on one’s own. Yet his distinction obscures the irreducibly social character of the solitary operations. This paper preserves Reid’s distinction while accommodating the social character of the solitary operations. According to Reid, the solitary operations presuppose the social operations, expressed in what he calls the ‘natural language’ of mankind—a language that communicates the intentions that give (...) rise to the agreements by which the conventions of artificial languages are developed. Using artificial languages, we begin to sort the world into kinds and to anticipate the regular events that make a practical difference in our lives, providing the general conceptions that give our trains of thought the order and regularity required to form the solitary operations. By using artificial languages, we adapt social operations to solitary ends, to think alone and in silence. (shrink)

Thomas Reid claims to share Locke's view that consciousness is a kind of inner sense. This is puzzling, given the role the inner-sense theory plays in indirect realism and in the theory of ideas generally. I argue that Reid does not in fact hold an inner-sense theory of consciousness and that his view differs importantly from contemporary higher-order theories of consciousness. For Reid, consciousness is a first-order representational process in which a mental state with a particular content suggests the application (...) of recognitional concepts in forming beliefs or judgements to the effect that one is currently undergoing a state with that content. I take up the question of whether Reid's theory leads to a regress, and I argue that while the regress cannot be eliminated, it is mitigated by the non-hierarchical nature of Reid's theory of mind.

Berkeley holds that vision, in isolation, presents only color and light. He also claims that typical perceivers experience distance, figure, magnitude, and situation visually. The question posed in New Theory is how we perceive by sight spatial features that are not, strictly speaking, visible. Berkeley’s answer is “that the proper objects of vision constitute an universal language of the Author of nature.” For typical humans, this language of vision comes naturally. Berkeley identifies two sorts of objects of vision: primary (light (...) and colors) and secondary (distance, figure, magnitude, and situation). Berkeley also appeals to a third class of a different sort: visible figure, magnitude, and situation, constituting the vocabulary of the language of vision. By considering two perceivers who lack this vocabulary we may better understand this third category and the difference between those who must learn the language of vision and those for whom it is a natural endowment.

The early modern period is arguably the most pivotal of all in the study of the mind, teeming with a variety of conceptions of mind. Some of these posed serious questions for assumptions about the nature of the mind, many of which still depended on notions of the soul and God. It is an era that witnessed the emergence of theories and arguments that continue to animate the study of philosophy of mind, such as dualism, vitalism, materialism, and idealism. -/- (...) Covering pivotal figures in philosophy such as Descartes, Hobbes, Kant, Leibniz, Cavendish, and Spinoza, Philosophy of Mind in the Early Modern and Modern Ages provides an outstanding survey of philosophy of mind of the period. Following an introduction by Rebecca Copenhaver, sixteen specially commissioned chapters by an international team of contributors discuss key topics, thinkers, and debates, including: -/- Hobbes, Descartes’ philosophy of mind and its early critics, consciousness, the later Cartesians, Malebranche, Cavendish, Locke, Spinoza, Descartes and Leibniz, perception and sensation, desires, mental substance and mental activity, Hume, and Kant. Essential reading for students and researchers in philosophy of mind, enlightenment philosophy, and the history of philosophy, Philosophy of Mind in the Early Modern and Modern Ages is also a valuable resource for those in related disciplines such as religion, history of psychology, and history of science.

This chapter discusses eighteenth-century British theories of perception, beginning with George Berkeley’s Essay Towards a New Theory of Vision. The chapter traces Berkeley’s influence through Thomas Reid, David Hume, David Hartley, Adam Smith and Dugald Stewart. The chapter presents theories of perception in this time a place a primarily concerned with metaphysics, mind and methodology rather than epistemology.

Why has Thomas Reid’s philosophy been neglected? One answer to this question might cite Reid’s treatment by critics of his day. But Reid may also have been neglected because his terminology suggests a kind of quaint, naive dogmatism: a “philosophy of common sense” might belong to a philosopher who resists skepticism by just saying “no” to all that fancy philosophizing. Indeed, Reid tells us in the Inquiry: “I despise Philosophy, and renounce its guidance, let my soul dwell with Common Sense.” (...) But Reid’s announcement holds only if skepticism can’t be refuted, and what Reid takes himself to have done is precisely that: refute skepticism. Philip de Bary’s Thomas Reid and Scepticism: His Reliabilist Response is an admirable account of Reid’s strongly philosophical response to skepticism. (shrink)

Some interpret Reid’s notion of a moral sense as merely analogical. Others understand it as a species of acquired perception. To understand Reid’s account of the moral sense, we must draw from his theory of perception and his theory of aesthetic experience, each of which illuminate the nature and operation of the moral faculty. I argue that, on Reid’s view, the moral faculty is neither affective nor rational, but representational. It is a discrete, basic, capacity for representing the real moral (...) properties of humans and human conduct. (shrink)
