Those concerned with Locke’s Essay have largely ignored his account of reflection. I present and defend an interpretation of Locke’s theory of reflection on which reflection is not a variety of introspection; rather, for Locke, we acquire ideas of our mental operations indirectly. Furthermore, reflection is involuntary and distinct from consciousness. The interpretation I present also explains reflection’s role in the acquisition of non-sensory ideas (e.g., ideas of pleasure, existence, succession, etc.). I situate this reading within the secondary literature on reflection and discuss its consequences for interpretations of Locke’s views on empiricism, knowledge, and personal identity.

One of the promising approaches to the problem of consciousness has been the Higher-Order Monitoring Theory of Consciousness. According to the Higher-Order Monitoring Theory, a mental state M of a subject S is conscious iff S has another mental state, M*, such that M* is an appropriate representation of M. Recently, several philosophers have developed a Higher-Order Monitoring theory with a twist. The twist is that M and M* are construed as entertaining some kind of constitutive relation, rather than being logically independent of each other. We may call this the Same-Order Monitoring Theory of Consciousness. In this paper, I discuss the nature of the Same-Order Monitoring Theory and argue for its superiority over the more traditional Higher-Order Monitoring Theory.

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.

Following a short introduction, this chapter begins by contrasting two different forms of higher-order perception (HOP) theory of phenomenal consciousness - inner sense theory versus a dispositionalist kind of higher-order thought (HOT) theory - and by giving a brief statement of the superiority of the latter. Thereafter the chapter considers arguments in support of HOP theories in general. It develops two parallel objections against both first-order representationalist (FOR) theories and actualist forms of HOT theory. First, neither can give an adequate account of the distinctive features of our recognitional concepts of experience. And second, neither can explain why there are some states of the relevant kinds that are phenomenal and some that aren.

Locke’s account of personal identity has been highly influential because of its emphasis on a psychological criterion. The same consciousness is required for being the same person. It is not so clear, however, exactly what Locke meant by ‘consciousness’ or by ‘having the same consciousness’. Interpretations vary: consciousness is seen as identical to memory, as identical to a first personal appropriation of mental states, and as identical to a first personal distinctive experience of the qualitative features of one’s own thinking. There is wide agreement, however, that Locke’s theory of personal identity is meant to complement his moral and theological commitments to a system of divine punishment and reward in an afterlife. But these commitments seem to require also a metaphysical criterion, and Locke is insistent that it cannot be substance. The difficulty reconciling the psychological and metaphysical requirements of the theory has led, at worst, to charges of incoherence and, at best, to a slew of interpretations, none of which is widely accepted.

Locke put forward the theory of consciousness as "internal Sense" or "reflection"; Kant made it inner sense, by means of which the mind intuits itself or its inner state." ¹ On that theory, consciousness is a perception-like second-order representing of our own psychological states events. The term "consciousness," of course, has many distinct uses.

Locke’s theory of personal identity was philosophically groundbreaking for its attempt to establish a non-substantial identity condition. Locke states, “For the same consciousness being preserv’d, whether in the same or different Substances, the personal Identity is preserv’d” (II.xxvii.13). Many have interpreted Locke to think that consciousness identifies a self both synchronically and diachronically by attributing thoughts and actions to a self. Thus, many have attributed to Locke either a memory theory or an appropriation theory of personal identity. But the former stumble on circularity and the latter is insufficient for Locke’s moral theory insofar as he is committed to a theory of divine rectification. The common problem is that Locke’s theory seems to demand an objective, or metaphysical, fact of a continuing consciousness that does not appeal to a traditional notion of substance for the continuity. I’m suggesting something new. In II.xxvii of the Essay, we see an ambiguity in Locke’s use of the term ‘consciousness’. Locke seems to see consciousness as both a mental state by means of which we are aware of ourselves as perceiving and as the ongoing self we are aware of in these conscious states. First, I make the textual argument why we should read Locke as having a conception of a metaphysical fact of a continuing consciousness that does not appeal to thinking or bodily substance to establish its continuity. I then argue that the metaphysical fact of an enduring consciousness is revealed to us as a phenomenological fact of experience. Due to the nature of certain kinds of perceptual situations we have an experience of ourselves as temporally extended. Although the text bears out that Locke seemed to think there is a fact of an ongoing consciousness, I argue that it is consistent with his reluctance elsewhere that he makes no further epistemological or ontological claims about it. Finally, I provide an account of Locke’s understanding of memory and its relation to consciousness that supports the claim that consciousness is something ontologically distinct from either thinking or bodily substance.

Locke has been accused of failing to have a coherent understanding of consciousness, since it can be identical neither to reflection nor to ordinary perception without contradicting other important commitments. I argue that the account of consciousness is coherent once we see that, for Locke, perceptions of ideas are complex mental acts and that consciousness can be seen as a special kind of self-referential mental state internal to any perception of an idea.
