The life that is unexamined is not worth living.  - Plato

He who is of a calm and happy nature will hardly feel the pressure of age, but to him who is of an opposite disposition youth and age are equally a burden. - Plato

Courage is knowing what to fear. - Plato

Good people do not need laws to tell them to act responsibly, while bad people will find a way around the laws. - Plato

Wonder is the feeling of a philosopher; and philosophy begins in wonder. - Plato

He whom love touches not walks in darkness. - Plato

There's a victory, and defeat; the first and best of victories, the lowest and worst of defeats which each man gains or sustains at the hands not of another, but of himself. - Plato

There are two things a person should never be angry at, what they can help, and what they cannot. - Plato
