The only thing that we know is that we know nothing and that is the highest flight of human wisdom.

Leo Tolstoy

?An eye for an eye leaves everybody blind.

Mahatma Ghandi

Wisdom is always an overmatch for strength.

Phaedrus

What we call wisdom is the result of all the wisdom of past ages. Our best institutions are like young trees growing upon the roots of the old trunks that have crumbled away.

Henry Ward Beecher

When you move amidst the world of sense, free from attachment and aversion alike, there comes the peace in which all sorrows end, and your life in the wisdom of the Self.

Bhagavad Gita
