Hayek, Life and Times, by Jim Powell
Lengthy biographical essay, with extensive quotes both from Hayek and others (including Keynes)
Internationally-acclaimed philosopher Karl R. Popper confided to Hayek, 'I think that I have learned more from you than from any other living thinker ...' ... Hayek had ... Popper speak at a seminar, and Popper expanded it into his most controversial book, The Open Society and Its Enemies (1945), a passionate attack on Plato and Karl Marx; Hayek helped find a publisher and persuaded colleagues at the London School of Economics to give Popper a teaching position — rescuing him from a hostile academic environment in New Zealand. Through the ups and downs of Hayek's life, Popper remained his closest friend.
Interview with Robert Nozick, by Robert Nozick, Julian Sanchez, 26 Jul 2001
Topics discussed include: ethics, science and philosophy, Karl Popper and the scientific method, Ayn Rand and epistemology, consciousness, relativism and the academic left and Nozick himself
Popper is famous for saying that induction can't be justified, that the only inferences that data support are to deductive consequences of the data .... Popper’s anti-inductive conclusions were always held to be counterintuitive, even ridiculous, but he swallowed them, and so did his followers. Now I'm saying something stronger than has been said thus far, namely, that their view is incoherent.
The Spirit of Humility [PDF], by Stanley Kober, Cato Journal, 1997
Discusses the recognition of the limits on human knowledge, which the author claims leads to the title spirit as evidenced in "the American experiment" and its possible lessons for European unification
That spirit [of humility] is also the spirit of modern science, but it was not always this way. In the Novum Organum, written in 1620, Francis Bacon defined empirical inquiry as an effort 'to seek, not pretty and probable conjectures, but certain and demonstrable knowledge.' ... Modern science takes a different view. In the words of Karl Popper (1969: 115), 'Scientific theories ... are genuine conjectures—highly informative guesses about the world which although not verifiable (i.e., capable of being shown to be true) can be submitted to severe critical tests.'
