 The first answer to this question that Kant rejects is that self-consciousness arises from some particular content being present in each of one’s representations. This material conception of self-consciousness, as we may call it, is suggested by Locke’s account of personal identity. According to Locke, “it being the same consciousness that makes a Man be himself to himself, personal Identity depends on that only, whether it be annexed only to one individual Substance, or can be continued in a succession of several Substances” (Essay 2.27.10). What Locke calls “the same consciousness” may be understood as some representational content that is always present in my experience and that both identifies any experience as mine and gives me a sense of a continuous self by virtue of its continual presence in my experience. One problem with this view, Kant believes, is that there is no such representational content that is invariably present in experience, so the sense of an ongoing self cannot possibly arise from that non-existent content (what Locke calls “consciousness”) being present in each of one’s representations. In Kant’s words, self-consciousness “does not yet come about by my accompanying each representation with consciousness, but rather by my adding one representation to the other and being conscious of their synthesis. Therefore it is only because I can combine a manifold of given representations in one consciousness that it is possible for me to represent the identity of the consciousness in these representations” (B133). Here Kant claims, against the Lockean view, that self-consciousness arises from combining (or synthesizing) representations with one another regardless of their content. In short, Kant has a formal conception of self-consciousness rather than a material one. Since no particular content of my experience is invariable, self-consciousness must derive from my experience having an invariable form or structure, and consciousness of the identity of myself through all of my changing experiences must consist in awareness of the formal unity and law-governed regularity of my experience. The continuous form of my experience is the necessary correlate for my sense of a continuous self.
