ABSTRACT
I would like to make some simple remarks—that to certain people will even appear simplistic—about the theory of categories in the hope that its relationships with genetic epistemology will emerge spontaneously or almost spontaneously. Before doing so, let me stress that, although I do not pay much attention to them here, the subtle distinctions introduced by Henriques appear to me to be interesting and also useful for genetic epistemology. In contrast, however, I would like to have us look at the theory of categories through a veil so that we perceive only its important contours—at least those contours that appear important to me.
