[W]e now know that the human animal is characterized by two great fears that other animals are protected from: the fear of life and the fear of death... Heidegger brought these fears to the center of his existential philosophy. He argued that the basic anxiety of [humanity] 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. - Ernest Becker
