"Have Gun-Will Travel," A Thinking Man's Western

I just started watching season 5 of Have Gun-Will Travel (1961-1962), sort of a thinking man's western.

Paladin, played by Richard Boone, is a well-paid gun for hire, who despite being "a knight without armor in a savage land," is a man of culture. He reads Dostoevsky, quotes Tennyson, speaks several languages, etc. He's also a ladies man. I don't remember Paladin being such an intellectual in the radio version.
