Utilitarianism

Bentham

Mill

Singer

Rule vs. Act

Other foms

hedonic calculus : system for calculating amount of pain or pleasure generated

intensity, duration, certainty, extent, remoteness, richness, purity

maximising quantity of pleasure not prioritising specific forms

1st principle : action should produce greatest happiness overall

2n principle : 1st principle can support everyday principles - customary morality

Crisp : Haydn and the oyster : choose Haydn as type of experiences are better than that of the oyster - mental pleasures are higher pleasures compared to oysters lower bodily pleasures

Haydyn and the oyster : choose oyster as smaller pleasures extended so eventually outweigh that of Haydyns life

preference util : not judged on pleasure or pain, but hoe they affect the preferences of everyone involved

ability to feel suffering grants personhood/moral status

CRITICISMS

Empiricist - all knowledge ultimately based on sense data - ethics based on experience

integrity problem : just because a person seeks happiness for themselves, does not mean they seek happiness for everyone else

against speciesism (discrimination against nonhuman animals)

Act Utilitarianism (Bentham) - assess each separate act according to whether it maximises pleasure over pain

Rule utilitarianism (Mill) - supports rules that on balance produce the greatest pleasure for society

Mill on Bentham - philosophy is too mechanical for humanity - only looks at morality and ignores aesthetic and sympathetic factors

Popper - Negative Utilitarianism - concerned with minimisation of pain - more pragmatic

would it be moral for 10 people to harm 5 people if pleasure greater than pain

no hierarchy

hard to quantify emotional

pleasure too subjective

BUT : happiness is also subjective, different depending on person

Higher pleasure - something that helps you progress eg. learning
Lower pleasure - animalistic eg. eating

"It is better to be a human being dissatisfied than a pig satisfied"

BUT : pleasures can contratst - is it okay to cut down forest to build a school

believes any animal preference is to live

fallacy of composition : Mill has not demonstrated that every mans happiness is good for everyone if not most desirable for individual

pleasure too simplistic, does not account for human complexity
