In ancient times it was understood that there was a transcendent moral order outside the self, built in to the fabric of the universe. If you violated that metaphysical order there were consequences just as severe as if you violated physical reality by placing your hand in a fire. The path of wisdom was to learn to live in conformity with this unyielding reality. That wisdom rested largely in developing qualities of character, such as humility, compassion, courage, discretion, and loyalty.
Modernity reversed this. Ultimate reality was seen not so much as a supernatural order but as the natural world, and that was malleable. Instead of trying to shape our desires to fit reality, we now seek to control and shape reality to fit our desires. The ancients looked at an anxious person and prescribed spiritual character change. Modernity talks instead about stress-management techniques.
