"In essence, this is the vegetarian (or, as one cult calls itself, a fruitarian) creed, but it has had remarkably little success. The urge to eat meat appears to have become too deep-seated. Given the opportunity to devour flesh, we are loth to relinquish the pattern. In this connection, it is significant that vegetarians seldom explain their chosen diet simply by stating that they prefer it to any other. On the contrary, they construct an elaborate justification for it involving all kinds of medical inaccuracies and philosophical inconsistencies."
