 While many philosophers after Descartes took up the issues related to consciousness left by Descartes, one possible exception is Spinoza. On some interpretations, he doesn’t have much to say at all about  consciousness.[7]  This is somewhat striking, given how much Spinoza had to say about ideas and the mind. However, this may be a reflection of just how thin Spinoza’s attribute of thought really is, bringing together what in Descartes were distinct concepts: will and intellect, judgment and perception, and the like, developing a fully naturalized account of the mind. And so it seems that, insofar as Spinoza has a theory of consciousness, it will be explained in terms of some other more fundamental feature of the mind.
