The preservation of health is a duty. Few seem conscious that there is such a thing as physical morality.

The ultimate purpose of religious life is to make this evolution move in a direction far more important to the destiny of the ego than the moral health of the social fabric which forms his present environment.

It contributes greatly towards a man's moral and intellectual health to be brought into habits of companionship with individuals unlike himself who care little for his pursuits and whose sphere and abilities he must go out of himself to appreciate.

The greatest happiness of the greatest number is the foundation of morals and legislation.

There is a set of religious or rather moral writings which teach that virtue is the certain road to happiness and vice to misery in this world. A very wholesome and comfortable doctrine and to which we have but one objection namely that it is not true.

I saw that all beings are fated to happiness: action is not life but a way of wasting some force an enervation. Morality is the weakness of the brain.

Morality is not the doctrine of how we may make ourselves happy but how we may make ourselves worthy of happiness.

Happiness and moral duty are inseparably connected.

Achievement of your happiness is the only moral purpose of your life and that happiness not pain or mindless self-indulgence is the proof of your moral integrity since it is the proof and the result of your loyalty to the achievement of your values.

He was as great as a man can be without morality.
