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.

The History of the Philosophy of Mind is a major six-volume reference collection, covering the key topics, thinkers and debates within philosophy of mind, from Antiquity to the present day. Each volume is edited by a leading scholar in the field and comprises chapters written by an international team of specially commissioned contributors. Including a general introduction by Rebecca Copenhaver and Christopher Shields, and fully cross-referenced within and across the six volumes, The History of the Philosophy of Mind is an essential resource for students and researchers in philosophy of mind, and will also be of interest to those in many related disciplines, including Classics, Religion, Literature, History of Psychology, and Cognitive Science.

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.

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.

Thomas Reid’s epistemological ambitions are decisively at the center of his work. However, if we take such ambitions to be the whole story, we are apt to overlook the theory of mind that Reid develops and deploys against the theory of ideas. Reid’s philosophy of mind is sophisticated and strikingly contemporary, and has, until recently, been lost in the shadow of his other philosophical accomplishments. Here I survey some aspects of Reid’s theory of mind that I find most interesting. I examine whether Reid is a mysterian about the mind, whether Reid has a direct realist theory of perception, and whether Reid has a higher-order, or “inner-sense,” view of consciousness. Along the way I will mention portions of the secondary literature that examine these aspects and point out whether and to what degree I part ways with the interpretations present in the literature.
