Strauss to Voegelin:
"[Popper] was beneath contempt: it was the most washed-out lifeless positivism trying to whistle in the dark, linked to a complete inability to think “rationally,” although it passed itself off as “rationalism”—it was very bad. I cannot imagine that such a man ever wrote something that was worthwhile reading, and yet it appears to be a professional duty to become familiar with his production."
Voegelin in reply: "The opportunity to speak a few deeply felt words about Karl Popper to a kindred soul is too golden to endure a long delay. This Popper has been for years, not exactly a stone against which one stumbles, but a troublesome pebble that I must continually nudge from the path, in that he is constantly pushed upon me by people who insist that his work on the “open society and its enemies” is one of the social science masterpieces of our times. This insistence persuaded me to read the work even though I would otherwise not have touched it. You are quite right that it is a vocational duty to make ourselves familiar with the ideas of such a work when they lie in our field; I would hold out against this duty the other vocational duty, not to write and publish such a work. In that Popper violated this elementary vocational duty and stole several hours of my lifetime, which I devoted in fulfilling my vocational duty, I feel completely justified in saying without reservation that this book is impudent, dilettantish crap. Every single sentence is a scandal, but it is still possible to lift out a few main annoyances."
