the primacy of feelings over reason vs. ethical system based on pure reason

FOCUSED ON HAPPINESS AS A LIFE GOAL.

BASED ON EMOTIONS THAN ON REASON. GRANDFATHER OF UTILITARIANISM.

IS, AND OUGHT ONLY TO BE, THE SLAVE OF PASSIONS.

ONE CANNOT DERIVE AN "OUGHT" FROM AN IS.

PRINCIPLE OF UTILITY

OF PLEASURE AND PAIN ARE THE BASIC CONSEQUENCES OF ETHICAL CHOICES.

HEDONISM: GOOD SHOULD BE THE FEELING OF PLEASURE. CUANTITATIVE.

HUMAN NATURE: WE'RE NOT EGOISTS. WE SYMPATHIZE WITH EACH OTHER.

ONE OUGHT ALWAYS TO DO WHATEVER WILL RESULT IN THE MOST HAPPINESS (UTILITY) FOR ALL CONCERNED.

ALL HUMAN BEINGS HAVE EQUAL ETHICAL STANDING. EGALITARIANISM.

WHAT MATTERS IS THE QUALITY OF THE PLEASURES—MORE IS NOT NECESSARILY BETTER.
