Quote by Oliver Wendell Holmes (1809-1894)

• The young man knows the rules, but the old man knows the exceptions.

• A word is not a crystal, transparent and unchanged; it is the skin of a living thought and may vary greatly in color and content according to the circumstances and time in which it is used.

• A moment's insight is sometimes worth a life's experience.

• Beware how you take away hope from another human being.

• Between two groups of people who want to make inconsistent kinds of worlds, I see no remedy but force.

• A mind that is stretched by a new experience can never go back to its old dimensions.
