despair would appear when an inherited or borrowed world-view (often of a collective nature) proved unable to handle unexpected and extreme life-experiences. Friedrich Nietzsche extended his views to suggest that the death of God—the loss of collective faith in religion and traditional morality—created a more widespread existential crisis for the philosophically aware. Existential crisis has indeed been seen as the inevitable accompaniment of modernism (1890–1945). Whereas Émile Durkheim saw individual crises as the by-product of social pathology and a (partial) lack of collective norms, others have seen existentialism as arising more broadly from the modernist crisis of the loss of meaning throughout the modern world.<ref>M. Hardt/K. Weeks, The Jameson Reader (2000) p. 265</ref> Its twin answers were either a religion revivified by the experience of anomie (as with Martin Buber), or an individualistic existentialism based on facing directly the absurd contingency of human fate within a meaningless and alien universe, as with Sartre and Camus. Irvin Yalom, an emeritus professor of psychiatry at Stanford University, has made fundamental contributions to the field of existential psychotherapy. Rollo May is another of the founders of this approach. Fredric Jameson has suggested that postmodernism, with its saturation of social space by a visual consumer culture, has replaced the modernist angst of the traditional subject, and with it the existential crisis of old, by a new social pathology of flattened affect and a fragmented subject. Historical context Existential crises are often seen as a phenomenon associated specifically with modern society. One important factor in this context is that various sources of meaning, such as religion or being grounded in one's local culture and immediate social environment, are less important in the contemporary context. Another factor in modern society is that individuals are faced with a daunting number of decisions to make and alternatives to choose from, often without any clear guidelines on how to make these choices. The high difficulty for finding the best alternative and the importance of doing so are often the cause of anxiety and may lead to an existential crisis. For example, it was very common for a long time in history for a son to simply follow his father's profession. In contrast to this, the modern schooling system presents students with different areas of study and interest, thereby opening a wide range of career opportunities to them. The problem brought about by this increased freedom is sometimes referred to
