Wisdom and penetration are the fruit of experience, not the lessons of retirement and leisure. Great necessities call out great virtues.

We are to seek wisdom and understanding only in the length of days.

In societies where mature workers are respected and where their wisdom is respected, everybody benefits. Workers are more engaged and productive. Their health is better. They live longer.

Wisdom has never made a bigot, but learning has.

Science gives us knowledge, but only philosophy can give us wisdom.
