 It is significant that Spinoza rarely used the term conscientia (in its various forms) in the Ethics, and when he does it is almost exclusively in parts 3 through 5, where Spinoza is considering the nature of specifically human affects and bondage or freedom with respect to them. Indeed, the few times Spinoza uses conscientia in Parts 1 and 2, he does so in a way that points forward to its use in the later part of the  Ethics.[9]
