Higher and lower pleasures
Mill states that higher pleasures are qualitatively better than lower pleasures and are of the mind, for example: Reading, viewing artwork, listening to classical music.
Lower pleasures are of the body and less enjoyable than mindful pleasures, for example: Sex, eating, and drinking alcohol.
His famous quote
“It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied. And if the fool, or the pig, are of a different opinion, it is because they only know their own side of the question.”
Higher and lower pleasures continued
Mill believes we must find an accurate balance of both higher and lower pleasures to reach a benchmark standard of morality, and only when we become experienced habitually, self conciously and self-observant can we reach this benchmark.
