Justice is the only worship.
Love is the only priest.
Ignorance is the only slavery.
Happiness is the only good.
The time to be happy is now,
The place to be happy is here,
The way to be happy is to make others so.
Wisdom is the science of happiness.

Happiness is the only good. The place to be happy is here. The time to be happy is now. The way to be happy is to help make others so.

Know, all the good that individuals find, Or God and Nature meant to mere Mankind, Reason’s whole pleasure, all the joys of Sense, Lie in three words, Health, Peace, and Competence. (Ibid., 11. 77–80)

After Nietzsche’s devastating criticism of those “last men” who “invented happiness,” there is probably no need for me to remind you of the naïve optimism with which we once celebrated science, or the technology for the mastery of life based on it, as the path to happiness. Who believes this, apart from a few overgrown children occupying university chairs or editorial offices?

Science seems to me to teach in the highest and strongest manner the great truth which is embodied in the Christian conception of entire surrender to the will of God. Sit down before fact as a little child, be prepared to give up every preconceived notion, follow humbly wherever and to whatever abysses nature leads, or you shall learn nothing. I have only begun to learn content and peace of mind since I have resolved at all risks to do this.

Happiness is the only good, reason the only torch, justice the only worship, humanity the only religion, and love the only priest.

These truths I hold to be self-evident: That man was made to be happy; that happiness is only attainable through useful effort; that the very best way to help ourselves is to help others, and often the best way to help others is to mind our own business; that useful effort means the proper exercise of all our faculties; that we grow only through exercise; that education should continue through life, and the joys of mental endeavor should be, especially, the solace of the old; that where men alternate work, play and study in right proportion, the organs of the mind are the last to fail, and death for such has no terrors.
