Philosophy
102 thinkers whose ideas shape what therapists actually do in the room
Every therapeutic modality makes philosophical assumptions — about what a person is, what suffering means, what change requires. Most clinicians inherit these assumptions through training without examining them. This tool makes them visible: 102 thinkers across 10 categories, traced from their ideas to their clinical implications.
Foundational Questions Six questions that divide clinical traditions — on the self, the body, language, freedom, and healing → Philosophical Debates Thinkers argue opposing positions on ethics, embodiment, the unconscious, and the therapeutic encounter →
