The foundations of existential therapy likely emerged from existential psychology (May, 1971), which itself drew from American existential philosophy, notably the works of William James (James, 2007) and John Dewey (Dewey, 2014), as well as European existentialism, including Kierkegaard (Kierkegaard, 1968) and phenomenology, with Ludwig Binswanger (Binswanger, 1971) as one of its most prominent figs. A key insight from May, referencing Nietzsche and Kierkegaard, is that humans are “the organism that attributes greater importance to certain values—such as prestige, power, tenderness, and love—than to pleasure, and even more so than to survival” (May, 1971). This observation anticipates the motivations of individuals drawn to radical, even dangerous and violent, paths. May prophetically added in 1971: “We halt the meaning of being… the modern man’s self-image, his experience, and his concept of himself as a responsible individual tend to disintegrate.”
