Each of us knows it all, and knows he knows it all—the rest, to a man, are fools and eluded. One man knows there is a hell, the next one knows there isn’t; one man knows monarchy is best, the next one knows it isn’t; one man knows high tariff is right, the next man knows it isn’t; one man knows there are witches, the next one knows there aren’t; one sect knows its religion is the only true one, there are sixty-four thousand five hundred million sects that know it isn’t so.
From The Wit and Wisdom of Mark Twain: A Book of Quotations
