In this paper, my main goal is to discuss two incompatible answers proposed to what I shall call, the objectivity seeking question (OSQ). The first answer is what I shall call the primacy thesis, according to which the third-person perspective is superior to that of the first-person perspective. Ultimately I will reject this answer. The second answer is what I shall call the skepticism thesis, according to which the distinction between the first-person perspective and the third-person perspective can be maintained without reducing to/explaining away the former in terms of the latter. This is the answer I will defend albeit with some qualification. In this case, I will advance my discussion by appealing to the metaphysics of conscious experience/phenomenal consciousness. Third and finally, I will consider some empirically motivated objections against the skepticism thesis. In this case, my focus will be on modern neuroimaging techniques such as functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and positron emission tomography (PET) and see whether or not they pose a serious threat against the skepticism thesis. My overall conclusion will be that science and subjectivity, which is rooted in the first-person perspective, can coexist in the sense of complementing each other.

The goal of this paper is to critically examine the objections of John Locke’s contemporaries against the theory of substance or substratum. Locke argues in Essay that substratum is the bearer of the properties of a particular substance. Locke also claims that we have no knowledge of substratum. But Locke’s claim about our ignorance as to what substratum is, is contentious. That is, if we don’t know what substratum is, then what is the point of proposing it as a bearer of properties? This question underlies the criticism Locke’s contemporaries raise against the notion of substratum. In section I, I lay out the context for Locke’s theory of substratum by pointing out his main motivation in proposing his theory. In section II, I give a brief analysis of the theory of substratum. In section III, I discuss the objections of Locke’s contemporaries against the theory of substratum.1 I focus on Edward Stillingfleet, Lee Henry, G. W. Leibniz and John Sergeant. In section IV, I conclude that there is no warrant to dismiss Locke’s theory of substance.
