There is a difference between sorrow and despair. Sorrow is pain for which there are sources of consolation. Sorrow comes from losing one good thing among others, so that, if you experience a career reversal, you can find comfort in your family to get you through it. Despair, however, is inconsolable, because it comes from losing an ultimate thing. When you lose the ultimate source of your meaning or hope, there are no alternative sources to turn to. It breaks your spirit.
What is the cause of this ‘strange melancholy’ that permeates our society even during boom times of frenetic activity, and which turns to outright despair when prosperity diminishes? De Tocqueville says it comes from taking some ‘incomplete joy of this world’ and building your entire life on it. That is the definition of idolatry.
