I read two books recently that are out of print. One of them (Georges Rey's Contemporary Philosophy of Mind) is $150 on Amazon, and out of stock. The other (Philosophical Grounds of Rationality: Intentions, Categories, and Ends) isn't on Amazon at all. Used bookstores are the only viable option.

Books are treasures. The second book is an enormously valuable source of wisdom. I am glad nobody vandalized that wisdom with marginalia and highlighting.
