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?
