Abstract
In this article, which is fourth in a series of six articles, I address the fourth concept of consciousness that the Oxford English Dictionary defines in its six main entries under the word consciousness. I first introduce this fourth concept, the concept of consciousness4. by identifying the previous three OED concepts of consciousness, which I have already discussed in this series of articles, and by indicating how that to which we make reference, respectively, by means of those three concepts is related to the referents of the concept of consciousness4. I then address the latter concept more directly by pursuing for the remainder of the article where the OED's fourm entry leads. Among other things, I am led to consider two competing accounts of consciousness4 that figure prominently in the OED entry, namely the intrinsic, self-intimational account of William Hamilton and the inner-eye, perceptionlike account of John Locke. Both kinds of account are very much with us today
