Horace Says . . .

You know how people lose their way in the woods-
one goes wandering off to the left, another to the right;
both are equally wrong, though each has strayed in a different
direction. So you may rest assured that if you're to be counted
mad the fellow who laughs at you is no saner himself.
He too has straw in his hair.

Book II, Satire 3, 48-53
