- A pioneering work that redefines the concept of probability from a philosophical standpoint.
- Written by John Maynard Keynes before his fame as an economist.
- Challenges classical and frequentist views, proposing that probability is a degree of rational belief, not just a number.
- Emphasizes logical reasoning under uncertainty, rather than relying only on statistical data.
- Introduces the idea that some probabilities cannot be precisely quantified, only partially known.
- Serves as a bridge between logic, epistemology, and mathematics.
