Alexander Campbell once declared “a solemn league and covenant” between philosophy and common sense. Campbell’s pronouncement is representative of a broader trend in the Restorationist movement to look favorably on the common sense response to skepticism—a response originating in the work of Scottish philosopher and former minister Thomas Reid.

I finish by arguing for phenomenal conservatism. (shrink)
