Knowledge grows by not only doubting your beliefs and believing your doubts, but by doubting your doubts and believing your beliefs.
We live in a culture that has, for centuries now, cultivated the idea that the skeptical person is always smarter than one who believes. You can be almost as stupid as a cabbage, as long as you doubt.
The fashion of the age has identified mental sharpness with a pose, not with genuine intellectual method and character. Today it is the skeptics who are the social conformists, though - because of powerful intellectual propaganda - they continue to enjoy thinking of themselves as wildly individualistic and unbearably bright.
