At about the same time that Rank wrote, Heidegger brought these fears to the center of existential philosophy. He argued that the basic anxiety of man is anxiety about being-in-the-world, as well as anxiety of being-in-the-world. That is, both fear of death and fear of life, of experience and individuation. Man is reluctant to move out into the overwhelmingness of his world, the real dangers of it; he shrinks back from losing himself in the all-consuming appetites of others, from spinning out of control in the clutchings and clawings of men, beasts and machines. As an animal organism man senses the kind of planet he has been put down on, the nightmarish, demonic frenzy in which nature has unleashed billions of individual organismic appetites of all kinds—not to mention earthquakes, meteors, and hurricanes, which seem to have their own hellish appetites. Each thing, in order to deliciously expand, is forever gobbling up others.
