 Fallibilism and skepticism were the topics of some papers written by Guillermo Hurtado (Mexico). Hurtado (2002a) holds that, although these two positions are closely related, one must keep them apart; he rejects fallibilism because it is revisionist. Not much later, he argues in favor of using more fine-grained epistemic terms. According to Hurtado (2005), one should distinguish various senses of “doubt”, introduce the notion of “suspicion”, and accept various degrees of certainty. His basic idea is to enrich the vocabulary of epistemology, including more sophisticated skeptical terms.
