Abstract

This article deals with the original subjective conception of probability by Bruno de Finetti, considered as the "logic of uncertain". It also tries to demonstrate how this conception involves the human condition itself, as to both its ethical and aesthetical aspects. Unlike in the framework of other theories, these aspects are not justified by themselves but are closely and consistently linked to the abovementioned epistemological conception. The latter is moreover very important to justify the "Utopia as a necessary precondition for every significant foundation of economics".
