"Those things, thoughts, beings, acts, and instincts which help us to the pleasurable experiences of life we call good, and those which deprive us of pleasure or which bring upon us painful experiences we call bad. This is the supreme standard—Utility. Is the thing, thought, being, act, or impulse useful? Does it lead directly or indirectly to happiness and well-being? If it does, it is right, proper, and good. If it does not, it is wrong, improper, and bad."
