Utilitarianism is so dumb a moral philosophy and code of conduct that it arose only in the 18th century, before which, for thousands of years, there is not a trace of its moral claim, there being moral philosophers for ages.
It is as the gasoline that pumps into the air in toxicity, the defecant of urbanity and of the masses. It has a plain and clear fallacy at its core, for morality is right and wrong, not better or worse!
