First principles thinking has a rich intellectual history spanning more than two thousand years. Understanding this tradition deepens your appreciation of the methodology and connects you to a community of rigorous thinkers.

Aristotle (384-322 BC) introduced the concept of arche - the starting point of knowledge. Adam Smith applied first principles to economics and moral philosophy. John Harsanyi and Kenneth Arrow, both Nobel laureates, contributed game theory and the economics of uncertainty. Their students and intellectual descendants continue to develop and apply these ideas.

In this topic, you will learn about the key figures in this tradition, their contributions, and how their insights connect to practical modern applications.
