The truth is that if a man wishes to remain in perfect mental breadth and freedom, he had better not think at all. Thinking is a narrowing process. It leads to what people call dogma. A man who thinks hard about any subject for several years is in horrible danger of discovering the truth about it.
—G.K. Chesterton, qtd. by A.E. Carnehl in “G.K. Day: Dogma Matters”
