”Take, for example, the act of lying. We hold the telling of truth as a value; we are not supposed to lie. Yet if everyone told the truth all the time so that one could have complete trust in what one is told, then the advantage that would accrue to a single liar in society would be immense. This is not a stable social situation. On the other hand, in a society of individuals in which everyone lied all the time, society would be unworkable. The equilibrium state seems to be one in which people tell the truth most of the time but occasionally lie, which is how the world really seems to be. In a sense, then, it is the liars among (and within) us that keep us both honest and on our guard. This kind of scientific analysis of lying can help us understand why we do it.”
Pagels, Heinz R.
