The Enlightenment philosophy has proven to be problematic but that does not imply the West is gone. The West is going through a period of awakening and transition to something new. Some new kind of question and answer or answers. 

The West besides being characterized by the Bible also depends a lot on philosophical questions. That is starting from Parmenides how is change possible? which resulted in Plato and Aristotle and the Middle Ages. Then the Enlightenment questions, What is a just society? and the Mind Body problem which resulted in a whole long list of people answering one or the other. Kant and Hegel were results of the second question--but also the first to some degree.  Now the questions and answers are changing.
