The Existential-Humanistic Lineage
From philosophy to psychotherapy — how questions about existence became clinical practice
Unlike most therapeutic lineages, this one does not begin with a clinician. It begins with philosophers who asked what it means to exist as a human being — to face death, to choose, to suffer, to encounter another person. Kierkegaard, Nietzsche, Husserl, Heidegger, Sartre, Merleau-Ponty, and Buber were not therapists, but their ideas about anxiety, freedom, embodiment, and relation became the philosophical substrate for an entire tradition of psychotherapy. Clinicians like Binswanger, Boss, May, Frankl, Rogers, Perls, Gendlin, and Yalom translated these philosophical insights into therapeutic practice — producing approaches that share a commitment to the person's lived experience over diagnostic categories, and to meaning over mechanism.
