Logans Three-Forces Model

A work for science, therapy, and self-understanding — precise, clear, and free from dogma.

Jack P. Logan is dedicated to exploring the fundamental psychological structures of human experience.
His approach combines precise observation, theoretical clarity, and a consistently practice-oriented way of thinking.

With the Three-Forces Model, he developed an independent theory that describes the interplay of Self, Drive, and Ego as the central dynamic of human action.
Logan works in an interdisciplinary manner, drawing on both classical and modern psychological models and integrating them into a clear, logically coherent framework.

His publications - including Against Oneself, The Psychosis Next Door, and The Silent Center Within Me - together with the present work, form the core of a comprehensive theory of consciousness that captures thinking, feeling, and acting within a new systematic structure.

Jack P. Logan lives and works in Germany.
