The eccentric spelling of the English language is preserved because of a pervasive meme that there are right and wrong ways to spell words. This meme has all kinds of support, including dictionaries, computer spell-checkers, and children's spelling bees. But before the Use a dictionary strategy-meme became prevalent during the 18th and 19th centuries, people spelled words any way they wanted. It's not True that there's one and only one correct way to spell a word-it's just a meme. As Mark Twain said, "'Tis a small mind cannot think of but one way to spell a word."

Not that there's anything wrong with consistent spelling-it enhances communication, after all-but it's important to start seeing that all of what we think of as the Truth is composed of memes, and most of those memes just came into our heads through programming, without any of our own conscious choice involved.
