Restoring F. P. Ramsey. “F. P. Ramsey has some claim to be the greatest philosopher of the twentieth century. In Cambridge in the 1920s, he singlehandedly forged a range of ideas that have since come to define the philosophical landscape. Contemporary debates about truth, meaning, knowledge, logic and the structure of scientific theories all take off from positions first defined by Ramsey. Equally importantly, he figured out the principles governing subjective probability, and so opened the way to decision theory, game theory and much work in the foundations of economics. His fertile mind could not help bubbling over into other subjects. An incidental theorem he proved in a logic paper initiated the branch of mathematics known as Ramsey theory, while two articles in the Economic Journal pioneered the mathematical analysis of taxation and saving.” All this before he died at the age of 26.
