Stream of thoughts is a stream of motives, hence its discontinuous nature. Motives need a way in and a way out, to be taken up or dropped according to the priorities of the moment, which are themselves motives of a stickier and less optional kind. The taking up and dropping gives the field of motives an algebraic nature, it brings with it the idea of the negative, the inverse. A motive is also a kind of identity, and in each case there is an identity associated with the dropping of a motive. Identity, like motive is relative, is context dependent, but the cancelling of a motive, less so. Hence the idea of an ultimate identity that is relative to the detachment from all motives, all context, to nothingness or death.
