That a flowing stream cannot befoul its own fountain, and that any one who says it does is a tyrant and a liar; that a mouse is too weak to fight a lion, but too strong for the cords that can hold a lion; that a fox who gets most out of a flat dish may easily get least out of a deep dish; that the crow whom the gods forbid to sing, the gods nevertheless provide with cheese; that when the goat insults from a mountain-top it is not the goat that insults, but the mountain: all these are deep truths deeply graven on the rocks wherever men have passed.
