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

A man of wisdom delights in water.

Knowledge is merely brilliance in organization of ideas and not wisdom. The truly wise person goes beyond knowledge.

A fool despises good counsel, but a wise man takes it to heart.

A common man marvels at uncommon things. A wise man marvels at the commonplace.

A man who has committed a mistake and doesn't correct it is committing another mistake.
