In an interview for the Australian Broadcasting Corporation: "Joseph Heller - Closing Time" (1998) by Ramona Koval http://web.archive.org/web/20000306044602/http://www.abc.net.au/rn/arts/bwriting/heller.htm <!-- accessdate=2007-08-30 -->
Context: The only wisdom I think I've attained is the wisdom to be skeptical of other people's ideology and other people's arguments. I tend to be a skeptic, I don't like dogmatic approaches by anybody. I don't like intolerance and a dogmatic person is intolerant of other people. It's one of the reasons I keep a distance from all religious beliefs. I think in this country and in Australia too there's a late intolerance in most religions, an intolerance, a part that could easily become persecutions.
We have some ultra-orthodox Jewish sects here in New York and I fear them as much as I would fear a Nazi organisation.

1940s, Philosophy for Laymen (1946)
Context: The demand for certainty is one which is natural to man, but is nevertheless an intellectual vice. If you take your children for a picnic on a doubtful day, they will demand a dogmatic answer as to whether it will be fine or wet, and be disappointed in you when you cannot be sure. The same sort of assurance is demanded, in later life, of those who undertake to lead populations into the Promised Land. “Liquidate the capitalists and the survivors will enjoy eternal bliss.” “Exterminate the Jews and everyone will be virtuous.” “Kill the Croats and let the Serbs reign.” “Kill the Serbs and let the Croats reign.” These are samples of the slogans that have won wide popular acceptance in our time. Even a modicum of philosophy would make it impossible to accept such bloodthirsty nonsense. But so long as men are not trained to withhold judgment in the absence of evidence, they will be led astray by cocksure prophets, and it is likely that their leaders will be either ignorant fanatics or dishonest charlatans. To endure uncertainty is difficult, but so are most of the other virtues. For the learning of every virtue there is an appropriate discipline, and for the learning of suspended judgment the best discipline is philosophy.
But if philosophy is to serve a positive purpose, it must not teach mere skepticism, for, while the dogmatist is harmful, the skeptic is useless. Dogmatism and skepticism are both, in a sense, absolute philosophies; one is certain of knowing, the other of not knowing. What philosophy should dissipate is certainty, whether of knowledge or of ignorance.
Talk of the Nation (3 May 1996)
“I've always been skeptical of people who say they lose themselves in a part.”
As quoted in "Innocent Revisited" in TIME magazine (29 June 1970)
Context: I've always been skeptical of people who say they lose themselves in a part. Someone once came up to Spencer Tracy and asked, "Aren't you tired of always playing Tracy?" Tracy replied, "What am I supposed to do, play Bogart?" You have to develop a style that suits you and pursue it, not just develop a bag of tricks.
Variant: I think art is the only thing that's spirtual in the world. And I refuse to be forced to believe in other people's interpretations of God. I don't think anybody should be. No one person can own the copyright to what God means.
