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.
