The war... was an unnecessary condition of affairs, and might have been avoided if forebearance and wisdom had been practiced on both sides.

The key to wisdom is this - constant and frequent questioning, for by doubting we are led to question and by questioning we arrive at the truth.

Silence at the proper season is wisdom, and better than any speech.

The wisdom of age: don't stop walking.

Wisdom is the power to put our time and our knowledge to the proper use.
