Edward Abbey once said that to read Robert Grudin is to experience "the rare and amazing spectacle of man thinking, of mind at work." Part do-it-yourself guide to freer thinking and part playful philosophical inquiry into liberty and creativity, On Dialogue holds forth the model of the mind that "rejects the tyranny of a single system or dogma, refuses to censor Ôdangerous' ideas, and guards as something precious its own access to joy and laughter."
Grudin graduated from Harvard, and earned a Ph.D. in comparative literature from the University of California, Berkeley in 1969. He received a Guggenheim Fellowship for 1992-1993. Until 1998 he was a professor of English at the University of Oregon. He has written about many political and philosophical themes including liberty, determinism, and several others.
