Self-Consistency: A Theory of Personality
Before Tony Robbins. Before Cialdini. Before Maltz. There was Lecky.In 1945, Columbia University psychologist Prescott Lecky published a quiet little book that would secretly shape the next 80 years of self-help, cognitive psychology, and identity-based change — and then almost disappeared from print.
This is that book. Restored. Annotated. Back in your hands.
Why this forgotten classic still mattersLecky was the first serious academic to argue something that sounds obvious today but was radical in his we don't behave according to reality — we behave according to the self-image we hold about ourselves. Every thought, every habit, every sabotaged goal, every unexpected success — all of it flows from one underlying the need to stay consistent with who we believe we are.
Sound familiar? It should. This single insight became the foundation
Maxwell Maltz's Psycho-Cybernetics (1960) — Maltz explicitly built on Lecky's self-image theoryThe entire cognitive behavioral therapy movement that followed in the 1960s and 70sModern identity-based habit frameworks used by today's top performance coachesThe core mechanics behind influence, persuasion, and behavior change researchYet almost nobody reads the original source. Until now.
What you'll discover insideWhy willpower fails — and what actually drives lasting change at the identity levelThe self-consistency principle: the hidden psychological force behind every choice you makeHow to predict human behavior (your own and others') with surprising accuracyWhy internal conflict erupts the moment your actions collide with your self-imageThe original case studies from Lecky's work with students, athletes, and everyday peopleWhy most self-help advice fails — and what Lecky saw 80 years ago that modern gurus are only now rediscoveringWho this 2nd Edition is forPsychology students and therapists who want to read the primary source instead of quoting it secondhand.
Coaches and self-development readers who are tired of recycled advice and want the original thinking.
Curious minds who have read Maltz, Robbins, Cialdini or Clear and "Where did these ideas actually come from?"
Anyone trying to understand why they keep acting against their own best interests — and how to finally stop.
What makes this 2nd Edition differentLecky's original text is in the public domain, which means dozens of low-effort reprints exist. This edition is
Carefully restored and re-typeset for modern readabilityEditorial context on how Lecky's ideas traveled through 80 years of psychologyA clean, reader-friendly layout — not a scanned blurCurated by editor Ansgar Holtmann to honor the original while making it accessible to today's readerScroll up, click "Add to Cart," and read the book that quietly built the modern self-help industry.
