The ancient Pyrrhonian skeptics suspended judgment about all philosophical views. Their main opponents were the Dogmatists—those who believed their preferred philosophical views. In Outlines of Skeptical-Dogmatism: On Disbelieving Our Philosophical Views, Mark Walker argues, contra Pyrrhonians and Dogmatists, for a “darker” skepticism: that we should disbelieve our philosophical views. On the question of political morality, for example, we should disbelieve libertarianism, conservativism, socialism, liberalism, and any alternative ideologies. Since most humans have philosophical beliefs, such as about religious and political matters, humanity writ large should disbelieve their preferred philosophical views. Walker argues that Skeptical-Dogmatism permits a more realistic estimation of our epistemic powers. Dogmatists who believe their view is correct, while believing that two or more competing views are false, must—at least implicitly—take themselves to be “über epistemic superiors” to their disagreeing colleagues. Such a self-assessment is as implausible as it is hubristic. Skeptical-Dogmatism, in contrast, permits a more realistic and humbler epistemic self-conception. Walker also shows that there are no insuperable practical difficulties in living as a Skeptical-Dogmatist.
