A sign is always less than the thing it points to, and a symbol is always more than we can understand at first sight. Therefore we stop at the sign but go on to the goal it indicates; but we remain with the symbol because it promises more than it reveals.
We tell lies when we are afraid. . . afraid of what we don't know, afraid of what others will think, afraid of what will be found out about us. But every time we tell a lie, the thing that we fear grows stronger.
