John Locke on thinking

A sound mind in a sound body is a short but full description of a happy state in this world.

New opinions are always suspected, and usually opposed, without any other reason but because they are not already common.

Virtue is harder to be got than knowledge of the world; and, if lost in a young man, is seldom recovered.

Great minds discuss ideas. Average minds discuss events. Small minds discuss people.
