 At the beginning of the previous section, we noted that Spinoza rarely uses the term conscientia, and when he does it is primarily in parts 3 through 5. This claim, while true, is somewhat misleading. Note that the quotation above from 3p9 refers us back to 2p23 for his claims about consciousness. And again in 3p30d, 3def.aff1, and 4p8d Spinoza refers us back to 2p23, 19, or 21. It seems clear that he intends 2p19 through 23 to have some consequence for his theory of consciousness, and so many commentators have tried to develop an account of consciousness from what Spinoza says in that section of the Ethics.
