Three Maxims on Knowledge, Belief, Action

  1. Don’t claim to know what you merely believe even on good evidence.
  2. Don’t claim to believe what you are not prepared to act upon.
  3. Don’t let insufficient evidence prevent you from believing what you are better off believing in the long run than not believing in the long run.
