Wisdom can only be learned gradually, and every soul is not ready to receive or to understand the complexity of the purpose of life.

Cleverness and complexity are not necessarily wisdom.

Wisdom is attained in solitude.

It is wise to see all things, and yet to turn our eyes from all that should be overlooked.

While man judges another from his own moral standpoint, the wise man looks also at the point of view of another.

You cannot be too wise, but you can be too clever.
