contemporaryAnalytic Philosophy1903 – 1930
Frank Plumpton Ramsey (1903–1930) was a British philosopher, mathematician, and economist who made extraordinary contributions to mathematical logic, probability theory, and the philosophy of language before his death at age 26. His work laid groundwork for subjective probability and Bayesian decision theory, and his papers on the foundations of mathematics remain influential. Despite his brief career, he is regarded as one of the most gifted analytic philosophers of the twentieth century.
