On The Structure of Scientific Revolutions, published mostly in 1962.

On John Rawls's A Theory of Justice (1971), most of ch. 1-4.

On Friedrich Nietzsche's The Gay Science (1882, with book 5 added 1887).

What is wisdom? Nietzsche gives us an updated take on the Socratic project of challenging your most deeply held beliefs. Challenge not just your belief in God (who's "dead"), but uncover all your habits of thinking in terms of the divine. Realize how little of your life is actually a matter of conscious reflection, and the consequent limits on self-knowledge. The very act of systematization in philosophy overestimates what we can know; instead, we need a "gay" (in the sense of cheerful, carefree, and subversive) science (in the sense of organized knowledge) that chases after fleeting insights and is able to question, i.e. laugh at, the pretensions of its own activity.

On Popper's Conjectures and Refutations (1963), the first three essays.

What is science, and how is it different than pseudo-science? From philosophy? Is philosophy just pseudo-science, or proto-science, or what? Popper thinks that all legitimate inquiry is about solving real problems, and scientific theories are those that are potentially falsifiable: they make definitely predictions about the world that, if these fail to be true, would show that the theory is false.
