7. Existence / C. Structure of Existence / 5. Supervenience / c. Significance of supervenience
The goodness of a picture supervenes on the picture; duplicates must be equally good
22. Metaethics / C. Ethics Foundations / 2. Source of Ethics / c. Ethical intuitionism
You can't use intuitions to decide which intuitions you should cultivate
How can intuitionists distinguish universal convictions from local cultural ones?
22. Metaethics / C. Ethics Foundations / 2. Source of Ethics / h. Expressivism
Emotivists mistakenly think all disagreements are about facts, and so there are no moral reasons
22. Metaethics / C. Ethics Foundations / 2. Source of Ethics / i. Prescriptivism
If there can be contradictory prescriptions, then reasoning must be involved
An 'ought' statement implies universal application
Prescriptivism implies a commitment, but descriptivism doesn't
If we have to want the preferences of the many, we have to abandon our own deeply-held views
If morality is to be built on identification with the preferences of others, I must agree with their errors
If morality is just a natural or intuitive description, that leads to relativism
Prescriptivism sees 'ought' statements as imperatives which are universalisable
Descriptivism say ethical meaning is just truth-conditions; prescriptivism adds an evaluation
Hare says I acquire an agglomeration of preferences by role-reversal, leading to utilitarianism
23. Ethics / B. Contract Ethics / 8. Contract Strategies
By far the easiest way of seeming upright is to be upright
23. Ethics / D. Deontological Ethics / 3. Universalisability
Moral judgements must invoke some sort of principle
The categorical imperative leads to utilitarianism
