#utilitarianism

"...the rarest of all human qualities is consistency."

"The creed which accepts as the foundation of morals, Utility, or the Greatest-Happiness Principle, holds that actions are right in proportion as they tend to promote happiness, wrong as they tend to produce the reverse of happiness. By happiness is intended pleasure, and the absence of pain; by unhappiness, pain, and the privation of pleasure."

"The end may justify the means as long as there is something that justifies the end."

"Happiness is a very pretty thing to feel, but very dry to talk about."

"Settle, for sure and universally, what conduct will promote the happiness of a rational being."
