The purpose of this dissertation is to argue that mental states are conscious when, and only when, they are intentionally directed at themselves. Thus, if for subject x to perceive a tree is for x to harbor an internal state which is intentionally directed at a tree, then for x to have a conscious perception of a tree is for x to harbor an internal state which is primarily directed at the tree and secondarily directed at itself. If so, consciousness is reductively explicable in terms of intentio…

Thus, if for subject x to perceive a tree is for x to harbor an internal state which is intentionally directed at a tree, then for x to have a conscious perception of a tree is for x to harbor an internal state which is primarily directed at the tree and secondarily directed at itself. If so, consciousness is reductively explicable in terms of intentionality. ;The argument of the dissertation proceeds in two phases. First, it is argued that the phenomenological feature common and peculiar to conscious states is intransitive self-consciousness, by which is meant the subtle and implicit self-awareness permanently accompanying the stream of consciousness. The first phase of the argument is to claim that it is this phenomenological feature, and, importantly, not the so-called sensory qualia often exhibited by conscious experiences, that is the mark of the conscious. ;The second phase of the argument is an account of intransitive self-consciousness in terms of the aforementioned sort of self-directed intentionality. It is argued, first, that self-directed intentionality is a necessary condition for intransitive self-consciousness, and second, that a specific kind of self-directed intentionality is also a sufficient condition for intransitive self-consciousness. ;The dissertation ends with a discussion of the prospects for naturalization, or demystification, of self-directed intentionality, and by consequence consciousness. A nomologically possible state of affairs is portrayed, in which physical states of the brain vehicle such self-directed intentionality. The nomological possibility of physically realized self-directed intentionality does not, of course, constitute a naturalization self-directed intentionality, but it does demonstrate the compatibility of self-directed intentionality with a physicalist-naturalist approach to consciousness
