Abstract

There are reasons to be skeptical of the claim that philosophy and science are making progress toward the complete truth of the universe and our place in it. I discuss two different kinds of skeptical worries about justifying contemporary philosophical and scientific beliefs. Widespread philosophical disagreement leads to a suspicion that most philosophers are probably wrong. In science there is more agreement, but science has not justified some of its basic assumptions including the use of Occam's Razor for theory selection. Worse, noetic skepticism questions whether humans even have the cognitive capacity for understanding the complete truth. We do not believe that children or apes have that capacity, so the question naturally arises within both philosophy and science as to whether we have reason to believe that adult humans are adequately equipped. Finally, I propose a scientific experiment to put this type of skepticism to the test.
