Concepts by Jerry Fodor is looking like a very good book. He takes the perspective of presenting concepts, within a cognitive system, as being basically atomic and simple ideas - rather than the general computational psychology model of proposing that semantic ideas only have meaning on their own - as compounds of concepts, rather than allowing for meaningful simple atomic concepts. I like having my work turn having been thought of earlier by experts, it gives me an idea that I'm on the right track.
