We are what our thoughts have made us; so take care about what you think. Words are secondary. Thoughts live; they travel far.

Wisdom cries out in the streets, and no man regards it.

The beginning of wisdom is a definition of terms.

There never was any heart truly great and generous, that was not also tender and compassionate.

The small wisdom is like water in a glass: clear, transparent, pure. The great wisdom is like the water in the sea: dark, mysterious, impenetrable.

The attempt to combine wisdom and power has only rarely been successful and then only for a short while.
