No one in this world, so far as I know- and I have researched 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 anyone ever lost public office thereby.

All human progress, even in morals, has been the work of men who have doubted the current moral values, not of men who have whooped them up and tried to enforce them.

It is common to assume that human progress affects everyone- that even the dullest man, in these bright days, knows more than any man of, say, the Eighteenth Century, and is far more civilized. This assumption is quite erroneous...The great masses of men, even in this inspired republic, are precisely where the mob was at the dawn of history. They are ignorant, they are dishonest, they are cowardly, they are ignoble. They know little if anything that is worth knowing, and there is not the slightest sign of a natural desire among them to increase their knowledge.

Every failure teaches a man something, to wit, that he will probably fail again.

Nature abhors a moron.

The world always makes the assumption that the exposure of an error is identical with the discovery of truth--that the error and truth are simply opposite. They are nothing of the sort. What the world turns to, when it is cured on one error, is usually simply another error, and maybe one worse than the first one.
