People like to retreat to within a thick, comfortable, traditional set of folkways, and not to worry too much about their structure, or their origins, or even the criticisms that they may deserve. Reflection opens the avenue to criticism, and the folkways may not like criticism. In this way, ideologies become closed circles, primed to feel outraged by the questioning mind. For the last two thousand years the philosophical tradition has been the enemy of this kind of cosy complacency.
