Philosophy

According to my "Philosophy Made Simple" book (which is an oxymoron of itself ... we cannot acquire knowledge through learning. One cannot learn what one does know since one already knows it. And one cannot learn what one does not know, since if one doesn't know it, one cannot recognize it as a truth when one learns it. Therefore, learning is impossible, and any knowledge that we can have we must already have." Clear as mud... What I figure is I am guaranteed an A since I do not have the ability to learn it! According to Plato, if I don't already know it, I can't learn it. Hmmm, I need to figure out how to use this to my advantage gradewise.
