Which Enlightenment thinker developed ideas about economics that are still referred to today?
Adam Smith.
Adam Smith thought about how wealth is made and traded, and his ideas are still quoted by economists and politicians. The handbook pairs him with David Hume, who worked on human nature. The easy way to keep them apart is that Smith is money and markets, Hume is the mind. Both belong to the Scottish Enlightenment.
Test Trap. Adam Smith (economics) is often confused with David Hume (human nature and philosophy). Smith = money; Hume = human.
Why it matters: Smith and Hume are a classic swap: economics versus human nature.
Memory hook: Adam Smith, the money-smith: he hammered out ideas about economics.
