All wisdom is rooted in learning to call things by the right name. When things are properly identified, they fall into natural categories and understanding becomes orderly.

When you meet someone better than yourself, turn your thoughts to becoming his equal. When you meet someone not as good as you are, look within and examine your own self.

Faithfulness and sincerity are the highest things.

To know that one knows what one knows, and to know that one doesn't know what one doesn't know, there lies true wisdom.

When we see persons of worth, we should think of equaling them; when we see persons of a contrary character, we should turn inwards and examine ourselves.
