Challenge of moral philosophy: a system which resolves morality and ethics together.

tools

  • definitions
  • appearance vs. reality (descriptive vs. true values)
  • reflective equilibrium

morality

morality is paradimatically a set of rules/expectations (concerning character/motives/emotions) for right/wrong behavior.

A code of conduct that people “must” follow to…

  • regulate / guide interpersonal interactions
  • rules that concern…
    • harm / benefit
    • justice / fairness
    • loyalty / obedience
    • sanctity / purity

Key question of morality: what do we owe to each other? what do I owe other people?

example

twelve commandments

  1. no other gods
  2. no idols
  3. no swearing
  4. keep sabbath holy
  5. honor parents
  6. don’t murder
  7. don’t commit adultery
  8. no stealing
  9. no lying
  10. no coveting

descritive morality

what people think or believe is right and wrong

  • privileging some kind of in-group

true morality

what is right and wrong

ethics

  • what’s a good life?
  • how should I live?
  • what should I do, all things considered?

modern morality

Modern morality has four typical features:

  • “universal” — applies to everyone
  • “impartial / egalitarian” — everyone counts the same, everyone is “equally real”
  • “inescapable” — you can’t ot out
  • “overriding” — morality is important, moral considerations are weighty + need to be taken seriously (“always beat others”)

theory

Why do we need theory?

  1. identify the “correct” rules / principles in a systematic way
  2. we want to know why these “correct” rules are correct
  3. why be moral?
  4. how do we know any of this? what’s the methodology?

coherentism

A coherentism is looping belief that forms the basis of a belief.

Agrippa’s Trilemma

Beliefs help justify observations.

digraph {
graph [bgcolor=transparent];
node [fontcolor=white, color=white];
edge [fontcolor=white, color=white];

observation [shape=rectangle];
dot [shape=none, label="..."]

belief1 -> "observation" -> belief2 -> {"belief3", "belief4"};
"belief4" -> observation [label="coherentism"];
"belief3" -> dot;
}

reflective equilibrium

once figure above reaches equilibrium, that’s reflective equilibrium
