Ebook: Metaphors We Live By

It would be hard to overstate how important this work is in contemporary philosophy, to say nothing of the other fields it has influenced. Aside from the more practical implications in understanding the way our minds work, it has some really radical arguments of the sort that would once have been called metaphysical, dealing with the nature of reality. In particular, it sheds light on the objectivist paradigm, showing that this way of treating the natural world is, after all, just one way of looking at things, useful in certain circumstances, but by no means universally valid (whatever that might mean).

Not exactly delightful prose, but clear and well organized.
