Supreme Happiness Consists In Self-content.

Virtue Is A State Of War, And To Live In It We Have Always To Combat With Ourselves.

Our Greatest Misfortunes Come To Us From Ourselves.

Education Is Either From Nature, From Man Or From Things. The Developing Of Our Faculties And Organs Is The Education Of Nature; That Of Man Is The Application We Learn To Make Of This Very Developing; And That Of Things Is The Experience We Acquire In Regard To The Different Objects By Which We Are Affected. All That We Have Not At Our Birth, And That We Stand In Need Of At The Years Of Maturity, Is The Gift Of Education.

No Man Has Any Natural Authority Over His Fellow Men.

One Can Buy Anything With Money Except Morality.
