If any of you want to read more into this...

I really recommend Steven Pinker's books, primarily The Stuff of Thought which I coincidentally started reading a few weeks ago. Pinker is very well respected in his field, and has written extensively on linguistics. Semantics, what we are essentially studying, is a subdivision of linguistics. I find that reading more into general linguistics aids in understanding semantics. In case you're worried about difficulty in reading Stuff of Thought, Pinker writes very accessibly, so the grasping of his ideas isn't blocked by any complicated jargon.
