Scepticism
Scepticism, the doctrines and opinions of the sceptics, whose distinguishing tenet was, that all things are uncertain and incomprehensible, and that the mind is never to assent to anything, but to remain in perpetual doubt and suspense. This doctrine was also called pyrrhonism, from the name of its author. See Pyrrhonians.
