If a lion could talk, we could not understand him.

If God had looked into our minds he would not have been able to see there whom we were speaking of.

A man's thinking goes on within his consciousness in a seclusion in comparison with which any physical seclusion is an exhibition to public view.

The human body is the best picture of the human soul.

Does man think because he has found that thinking pays? Does he bring his children up because he has found it pays?

But if you say: "How am I to know what he means, when I see nothing but the signs he gives?" then I say: "How is he to know what he means, when he has nothing but the signs either?"

So in the end when one is doing philosophy one gets to the point where one would like just to emit an inarticulate sound.
