 Thus, Weinberg contends that the identity, or continued existence, of consciousness consists in a metaphysical fact, rather than appropriation. Nevertheless, Weinberg additionally argues that the first personal (conscious) experience of our own mental states, whether those states are occurrent sensations, reflections, or via remembering is a necessary, but not sufficient, condition of personal identity. In other words, to have the awareness (or knowledge) of an ongoing self—or (2)—we must have (1). Although there is a range of interpretations of Locke on consciousness on the table, Weinberg’s book, Consciousness in Locke, marks the first large-scale treatment of Locke’s views on  consciousness.[6]
