Richard Jeffrey

Richard Jeffrey was a philosopher known for his work in epistemology and the philosophy of probability, particularly related to Confirmation Theory. He proposed that belief should be understood as a tool for handling uncertainty rather than a static state. Jeffrey suggested that we update our beliefs based on new evidence using a framework called "probability kinematics," which enables us to adjust our beliefs in a rational manner as we encounter new information. His ideas emphasize that belief change is about revising probabilities rather than simply accepting or rejecting ideas outright, thereby enriching our understanding of how we form and adjust beliefs.
