Episode notes
Qualia Are Inputs Not Moral Determinants
- Qualia (sensory feelings) are raw material for moral thought but don't determine moral conclusions.
- Deutsch argues different qualia can be provided artificially and moral goodness depends on creative moral problem solving, not base sensations.
Criticize Moral Theories Like Scientific Hypotheses
- Treat moral theories like scientific conjectures: propose, test against consequences, and improve through criticism.
- Deutsch points to historical moral progress (Euthyphro, Abraham) as examples of error-correction driving convergence.
Metamorality Uses The Golden Rule And Tolerance
- Metamorality includes techniques like imagining the other's viewpoint; these methods became central to modern moral improvement.
- Deutsch links tolerance of dissent and treating disputes as competing theories to Enlightenment moral gains.
