I do not know whether there are gods, but there ought to be.

It is the privilege of the gods to want nothing, and of godlike men to want little.

I know nothing, except the fact of my ignorance.

As to the gods, I have no means of knowing either that they exist or do not exist. For many are the obstacles that impede knowledge, both the obscurity of the question and the shortness of human life.

I don't know whether I like it, but it is what I meant.

The sun too penetrates into privies, but is not polluted by them
