Frank Ramsey

Frank Ramsey was a British philosopher and mathematician who significantly contributed to the philosophy of probability and decision theory. He argued that probabilities represent an individual's degrees of belief rather than objective properties of the world. According to Ramsey, rational choice involves aligning one's choices with these beliefs while also considering potential outcomes. His work laid the foundation for understanding how decisions are made under uncertainty, emphasizing that coherent beliefs and choice behavior can be mathematically structured, which has implications for economics, logic, and social science.
