What is a BIG question?

It’s not easy to say precisely what makes a question big; but we can at least give a few examples from the history of philosophy so that we have some idea what we’re talking about:

  • What is the meaning of life?
  • What is the nature of ultimate reality?
  • What is Being?
  • Is there a god?
  • Is there some sort of cosmic justice?
  • What is the self ?
  • Does a person’s self (mind, soul) persist after death?
  • Do we have free will?
  • Why be moral?
  • What is the good life for a human being?
  • What are the foundations of our knowledge?
  • What are the limits to what we can know?
  • What is truth?
  • What is the good?
  • What is justice?
  • What is virtue?
  • What is beauty?
  • What is life?
  • Why is there something rather than nothing?
