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.

Towards the end of her seminal work on the notion of representation Hanna Pitkin makes the following observation:

In the Categories Aristotle defined substance as that which is neither predicable of nor in another. In saying that a substance is not predicable of another, Aristotle meant to exclude genera and species from the category substance. Aman is a substance but not man. In saying that a substance is not in another, Aristotle meant to exclude property particulars from the category. A man is a substance, not his color.

The Categories treats substances as simples. Though a particular substance, Bucephalus the horse, has parts, it is nevertheless a single entity in the category substance and, hence, incomplex in the way a black thing or a running man are not. Black things and runners are complex because they are aggregates of substances and property particulars. Even if a horse is one substance and, thus, an entity (unlike a substance cum some of its attributes or a group of related substances), a horse is made of parts and one may wonder how it is related to its parts, as well as how its being made of parts coheres with the definition of substance given in the Categories.

What role do the first principles of morals play in Reid's moral theory? Reid has an official line regarding their role, which identifies these principles as foundational propositions that evidentially ground other moral propositions. I claim that, by Reid's own lights, this line of thought is mistaken. There is, however, another line of thought in Reid, one which identifies the first principles of morals as constitutive of moral thought. I explore this interpretation, arguing that it is a fruitful way of understanding much of what Reid wants to say about the role of moral first principles and drawing some connections between it and recent work on moral nonnaturalism.

After introducing Millianism and touching on two problems raised by genuinely empty names for Millianism (section I), I provide a brief exposition of the Gappy Proposition View (GPV) and of how different versions of this view can reply to the problems in question (section II). In the following sections I develop my reasons against the GPV. First, I will try to argue that apparently promising arguments for the claim that gappy propositions are propositions are not successful (section III). Then, I will develop two arguments against GPs via demonstrating two odd consequences of the GPV: (a) that there can be an atomic proposition which contains other propositions that are not the semantic contents of any part of the sentence expressing that atomic proposition, and (b) that propositional structures are propositions (section IV). And finally, I will attempt to show that if any of these views can provide a successful defense of Millianism, it can do so without GPs, given some slight changes (section V). I will conclude that GPs should be avoided (section VI).

According to a prominent line of thought, we can be physicalists, but not reductive physicalists, by holding that mental and other ‘higher-level’ or ‘nonbasic’ properties — properties that are not obviously physical properties — are all physically realized. Spelling this out requires an account of realization, an account of what it is for one property to realize another. And while several accounts of realization have been advanced in recent years, my interest here is in the ‘subset view,’ which has often been invoked explicitly in defense of nonreductive physicalist positions.

My aim in this paper is to show that animal motives play an important role in guiding human agents to virtue, according to Reid. Animal motives, for Reid, are constituted of desires and of their objects. These desires are intrinsic desires for objects other than moral or prudential worth. However, from a rational and moral point of view, animal motives are good and useful parts of the human constitution that lead to happiness, teach self-government, create the habit of acting virtuously, and add force to rational motives. Understanding animal motives as guides to virtue provides Reid with the hybrid sentimentalist/rationalist account he seeks to offer.

This paper explains the nature and role of common sense in Reid and uses the exposition to answer some of Reid's critics. The key to defending Reid is to distinguish between two kinds of priority that common sense beliefs are supposed to enjoy. Common sense beliefs enjoy epistemological priority in that they constitute a foundation for knowledge; i.e. they have evidential status without being grounded in further evidence themselves. Common sense beliefs enjoy methodological priority in that they constrain philosophical theory: they serve as pre-theoretical commitments that philosophical theories ought to respect in the absence of good reasons for rejecting them.
