Subjectivism, Objectivism and Objectivity in Bruno de Finetti's Bayesianism [chapter]

Maria Carla Galavotti
2001 Applied Logic Series  
The paper will focus on Bruno de Finetti's position, which combines Bayesianism with a strictly subjective interpretation of probability. For de Finetti, probability is always subjective and expresses the degree of belief of the evaluating subject. His perspective does not accommodate a notion of "objective chance" in the way other subjectivists, including Frank Ramsey, do. To de Finetti's eyes, objectivism, namely the idea that probability depends entirely on some aspects of reality, is a

For him there is no problem of objectivity beyond that of the evaluation of probabilities in a Bayesian framework. This is a complex procedure, which includes subjective elements as well as the consideration of objective elements like observed frequencies.
