I Talked to a Genius and All I Got was Knowledge

Bryan Frances’s recent argument is for the epistemic position called Live Skepticism. The Live Skepticism Argument (LSA) attempts to establish a restricted set of skeptical conclusions. The LSA’s “skeptical hypotheses” are scientific and philosophical positions that are “live actual possibilities” in an intellectual community. In order to “rule out” live hypotheses, an expert must know them to be false. However, since these are live hypotheses in this expert’s intellectual community—endorsed by others who have parallel levels of knowledge, intelligence, and understanding—this expert is unable to rule them out. Consistent with the LSA is the outcome that people not exposed to these live hypotheses can know what these experts cannot. However, in this paper, I defeat the LSA by developing and defending a counterexample that focuses on the phenomenon of genius testimony. Everyone, including the LSA’s proponent, can and should allow that expertise comes in degrees. While in many cases a person’s intelligence, understanding, and knowledge are parallel to others in the field, there are some who are extraordinary in their intelligence, understanding, and knowledge (geniuses). If an expert meets with a genius, it is possible that the genius provides this individual with beliefs that can rule out a skeptical hypothesis. Therefore, an expert can have knowledge, even if the skeptical hypothesis is live and endorsed by others who have parallel levels of knowledge, intelligence, and understanding. After providing this counterexample, I present three potential objections, and show how people can know global warming exists and that smoking does not give someone cancer. I conclude by defending this counterexample from a likely reply by proponents of the LSA involving luck and knowledge.
