  The same was true until recently of the  unity of consciousness  and Kant’s work on it. However, this is changing. In the past twenty years, the unity of consciousness has come back onto the research agenda and there are now hundreds of papers and a number of books on the topic. However, claims such as Kant’s that a certain form of synthesis and certain links among the contents of experience are required for unity continue to be ignored in cognitive science, though a few philosophers have done some work on them (Brook 2004). The same is true of Kant’s views on consciousness of self; cognitive science has paid no attention to non-ascriptive identification of self and the idea of the essential indexical. Here, too, a few philosophers have worked on these issues, apparently without knowing of Kant’s contribution (Brook &amp; DeVidi, 2001), but not cognitive scientists.
