 In Mexico, there is also a deep interest in skepticism. History of skepticism was not neglected, as we can be seen from the works of Laura Benítez and José Antonio Robles, among others, both of whom worked with Olaso (and Popkin). Their focus is on modern skepticism. Some Mexican philosophers, working within a Kantian tradition, focused on transcendental arguments as weapons against skepticism. Others work on contemporary skepticism in connection to questions such as disjunctivism and perception. Finally, skepticism and its connections to fallibilism and skeptical or epistemic concepts, such as doubt and certainty, were a major theme of some Mexican philosophers.
