 Foucault maintains that the great “turn” in modern philosophy occurs with Kant (though presumably he is merely an example of something much broader and deeper). Kant raises the question of whether ideas do in fact represent their objects and, if so, how (in virtue of what) they do so. In other words, ideas are no longer taken as the unproblematic vehicles of knowledge; it is now possible to think that knowledge might be (or have roots in) something other than representation. This did not mean that representation had nothing at all to do with knowledge. Perhaps some (or even all) knowledge still essentially involved ideas’ representing objects. But, Foucault insists, the thought that was only now (with Kant) possible was that representation itself (and the ideas that represented) could have an origin in something other than representation.
