His later work gave a more balanced account of how reason and feeling work together. These summaries and problems deal with Hume's Treatise of Human Nature and Enquiry Concerning the Principles of Morals. Reason and Desires Reason is the discovery of truth and falsehood. Tis not contrary to reason to prefer the destruction of the whole world to the scratching of my finger. Reason's only purpose is to help us to satisfy our desires.
Reason is, and ought only to be, the slave of the passions.
Morality Isn't from Reason Hume gave two arguments to show that morality isn't from reason. But moral judgments have such influence. So moral judgments aren't judgments of reason. Morality is from feeling, not from reason. Morality is more properly felt than judged.
