There is only one good, knowledge, and one evil, ignorance
Classical Greek (Athenian) philosopher credited as one of the founders of Western philosophy, and as being the first moral philosopher, of the Western ethical tradition of thought.
It is the mark of an educated mind to be able to entertain a thought without accepting it
He who hid well, lived well
The world of reality has its limits; the world of imagination is boundless
Excess of silence produces awe
The scientific observer of Nature is a kind of mystic seeker in the act of prayer
The tongue like a sharp knifeā¦ Kills without drawing blood
