Ethical Naturalism
Moral properties = natural properties. Meaning features/aspects of the physical world. Makes naturalism a form of moral realism
Example of Ethical Naturalism
Bentham’s utilitarianism form an ethical naturalism, claims that goodness is pleasure and that pleasure is a natural property we seek
Hume’s is/ought gap
Benthams argument for naturalism is that human nature is to find pleasure - we cannot help but link pleasure to goodness
Infers our ethical judgements is from our feelings - we move too easily from factual statements - is to ought. We cannot empirically detect the vice/wrongness
Mill about naturalism
MILL argues that happiness is the ultimate desire, goodness - what is good for us might not be good. Better to be a human dissatisfied than a pig satisfied
Naturalism on good/bad
See these as empirical facts. Ie - Natural law: Aquinas views the world as having a God-given order: good observed via purpose/telos
Mill FOR naturalism
We are able to know what is good or desirable - things that people actually desire
Significant agreement in values throughout cross-cultural regions: reduce morality to a matter of opinion wrong
ie. comparing holocaust to food preferences
Naturalistic fallacy
If something is natural must be good ie. canines to eat meat does not make vegetarians morally wrong.
G.E Moore against Ethical naturalism
Criticism of Mill’s naturalism in open question argument - pleasure cannot be the same thing as goodness - still possible to ask if goodness is truly good - naturalism makes assumptions ie. Aquinas on telos/purpose: existentialists reject assumption
Foot on ought/is
No problem in deriving ought from is - ought functions like need ie plant.
Aristotellian moral precepts: fluorishing natural property of organisms ie. plant needing sun to fluorish

MacIntyre on Ethical Naturalism
Modern societies focus on abstract law improved without foundation / apparent connection to the facts of communal human practice
Nozick’s thought experiment
Demonstrates the dangers of basing moral judgements on natural properties
By demonstrating that people prefer a less-than-perfect real life over a perfect simulated one, Nozick implies that “the good” cannot be reduced to a purely naturalistic, internal state of pleasure.
If happiness is just pleasure, then the machine should be the ultimate goal.
If we refuse it, then “the good” includes external factors like authenticity, agency, and truth.
Intuitionist
Good/bad are non-natural properties: not natural, but real in some sense
Analogy of the colour yellow
Yellow doesn’t have any distinguishable properties: just intuitively know it. Same w/ good/bad
Is intuitionalism cognitivist?
Yes, we can gain knowledge on ethical propositions
G.E Moore open argument
Goodness is an open question, cannot be defined by itself
Intuitionalism vs moral disagreement
Evidence FOR intuitionism = cross-cultural moral agreements in a core set of moral codes: all culture have rules about killing/stealing - we share intuition of right/wrong
Understanding of the word good = explain moral disagreements
Mackie against intuitionalism
Points out descriptive moral relativism - there is also mass cross-cultural moral disagreements. Doesnt prove meta ethical relativism - no non-natural: doesn’t provide absolutist argument against this
Defence of intuitionism against Mackie
Inconsistency in moral reasoning a product of the social climate, strengthen that adding moral agreements abd evolutionary drives
Freud against intuitionalism
Moral agreements a result of social conditioning - basic constructions to be in relation to society ie no stealing/killing
Isn’t intuition, but developed on by countless years of progression and trial and error
Intuitionism on the fact-value challenge
moral values separate from empirical world - unlike empiricism, able to establish moral facts that ensure right and wrong
Evolution against intuitionism
Evolutionary explanations of morility ie Darwins or psychological evaluations like Freuds idea on social conditioning better to account on morality - certain things are right/wrong
WD Ross FOR intuitionism
Know intuitionally when to help others - prima facie dtuies
Prichard FOR intuitionism
Morality is like common sense
Kahneman AGAINST intuitionsim
Intuitions like are driven by fear - emotions are machines for jumping for conclusions
