 Among the anti-skeptical strategies, the one that invokes transcendental considerations deserves special mention. A group of philosophers in Mexico is the most distinguished one concerning this Kantian-Strawsonian-inspired answer to skepticism. Pedro Stepanenko (Mexico) explored the anti-skeptical potential of the Kantian concept of the synthetic unity of apperception in many papers (2001, 2002a, 2006, 2007, 2008). According to his interpretation, this unity should be considered as the unity of our mental states that is possible only through the inferential relations to their contents. This unity makes possible the self-consciousness that any argumentative practice requires. If we could suspend judgment with respect to any subject, we would renounce to establish inferential relations among the contents of our mental states; in that case, there would be no consciousness unity, nor knowledge of our mental states.
