No one in this world, so far as I know--and I have searched the records for years, and employed agents to help me--has ever lost money by underestimating the intelligence of the great masses of the plain people. Nor has any one ever lost public office thereby. The mistake that is made always runs the other way. Because the plain people are able to speak and understand, and even, in many cases, to read and write, it is assumed that they have ideas in their heads, and an appetite for more. This assumption is folly. They dislike ideas, for ideas make them uncomfortable.

A metaphysician is one who, when you remark that twice two makes four, demands to know what you mean by twice, what by two, what by makes, and what by four. For asking such questions metaphysicians are supported in oriental luxury in the universities, and respected as educated and intelligent men.

My belief in free speech is so profound that I am seldom tempted to deny it to the other fellow. Nor do I make any effort to differentiate between the other fellow right and that other fellow wrong, for I am convinced that free speech is worth nothing unless it includes a full franchise to be foolish and even...malicious.

Human life is basically a comedy. Even its tragedies often seem comic to the spectator, and not infrequently they actually have comic touches to the victim. Happiness probably consists largely in the capacity to detect and relish them. A man who can laugh, if only at himself, is never really miserable.
