All that the posture of skepticism accomplishes is to freeze the ego in an ignorantist poverty that never stretches or diversifies its resources of imagination or understanding. Any uncultured cretin can close his eyes and try to reduce the issues down to linear simplisms and say, "I am doubting, I am proving my magisterial or sovereign control over my own mind." Doubt is a useful and significant test of one's critical powers, but by itself it bears little if any significant cultural charge of enlightenment or satori; indeed it is the very opposite kind of thing.
