Fallibilism is the philosophical idea that human knowledge is always subject to revision and correction. It suggests that no belief or theory can be considered absolutely certain, as new evidence or perspectives may emerge that challenge existing views. This concept encourages a mindset of openness and humility in the pursuit of knowledge. The roots of fallibilism can be traced back to thinkers like Charles Sanders Peirce and William James, who emphasized the importance of inquiry and the provisional nature of beliefs. By acknowledging the limitations of our understanding, fallibilism promotes a more flexible approach to learning and reasoning.
