Utilitarian theory of morality:

"[A]ctions are right in proportion as they tend to promote happiness, wrong as they tend to produce the reverse of happiness." (IP3 582a)

Utilitarian theory of life:

"[P]leasure, and freedom from pain, are the only things desirable as ends; and ... all desirable things ... are desirable either for the pleasure inherent in themselves, or as a means to the promotion of pleasure and the prevention of pain." (IP3 582a)

According to the utilitarian theory of life, only the following things are good or desirable or have positive value:

• pleasure
• freedom from pain
• things having inherent pleasure
• things that lead to (an increase) in pleasure
• things that prevent (or lead to a decrease in) pain
