Intolerance

Some people say this attitude is "intolerant." "He's the sort of man," they complain, "who thinks his own beliefs are true and everyone else's are wrong." But after all how can any man help doing that? A man must think his own belief true because if he didn't it would not be his belief. "Your belief" means "what you think true." And if you think the thing true, of course you must think the opposite false. But this is a very different thing from saying that those who hold the opposite belief are necessarily bad or stupid. --C. S.
