What My Approach Rests On

What my approach rests on

This isn’t just my opinion

When I say a compulsive behaviour is a conditioned habit and not a disease, that is not a comfortable position I picked. It is what I have been seeing for more than twenty years — and it is also what a neuroscientist who studied the question closely, and lived it himself, describes.

The reference book

The Biology of Desire

Why Addiction Is Not a Disease

Marc Lewis
Developmental neuroscientist and clinical psychologist.
Professor at the University of Toronto from 1989 to 2010, then at Radboud University in the Netherlands.

Published in 2015.

Marc Lewis was a heroin addict at seventeen. He lost his job, his relationship, his place in graduate school. He came out of it, and then became the researcher who would spend his career understanding what had happened to him.

That is what makes his book different from the others. He is not defending a theory from behind a desk: he describes from the inside a mechanism he later found in brain imaging, then followed in five people whose full stories he tells — the descent and the way out.

His conclusion fits in one sentence: what happens in the brain of an addicted person is not a pathology. It is learning — powerful, repeated, and perfectly normal in the way it works.

Five ideas from the book, and what they change for you

They follow in order: what the problem is, how it works, why willpower can’t beat it, and what makes change possible.

01

A brain that learned can learn again

Lewis shows that the changes seen in an addicted person’s brain are the same kind produced by any deep learning: falling in love, becoming a musician, a religious conversion. The circuit strengthens because it serves a purpose and because it is repeated. Nothing in it is broken.

And if it is learning, then it is reversible. Neuroplasticity does not stop in adulthood — it is in fact what made the conditioning possible in the first place.

02

Wanting is not liking

Dopamine does not produce satisfaction: it produces anticipation. It pushes toward, it does not reward. As the conditioning settles in, the brain becomes hypersensitive to the cues attached to the behaviour — and the gap widens: the urge goes up while the pleasure goes down.

That explains the sentence I hear most often: “it doesn’t even do anything for me anymore, and I keep doing it.” That is not a contradiction. It is exactly what the mechanism predicts.

03

The time horizon shrinks

Under the pull of the urge, attention narrows onto the immediate. The future stops carrying weight — not because the person doesn’t care about it, but because the present suddenly fills all the available space. Lewis calls it the lure of now.

That is why a decision made on Monday morning does not hold at nine on Friday night. It isn’t a different person deciding: it is the same person with a different horizon.

04

Resisting depletes you — and depletion wins

Every time you hold back an impulse, you draw on a limited resource. Lewis describes ego fatigue as the great enemy of the person trying to stop: they hold, they hold, they hold — and one evening they give in without knowing why, often after a day when nothing in particular happened.

So willpower is not a question of character. It is a resource that gets spent, facing a system that never gets tired.

05

You don’t get out by erasing a desire, but by redirecting it

This is the most important part of the book, and the most hopeful. For Lewis, recovery comes neither from deprivation nor from understanding alone: it comes from realigning desire toward something that matters more, and from a story of yourself that connects the past, the present and a possible next chapter.

In other words: you don’t get out of a compulsive behaviour by becoming someone who holds back. You get out by becoming someone for whom that behaviour no longer has a use.

What I have to be clear about

Marc Lewis’s position is contested. The disease model remains dominant in medicine, and serious researchers defend it with good arguments. I am not claiming the question is settled, and it would be dishonest of me to present this book to you as proof.

What I am telling you is simpler: here is a rigorous scientific reading that matches what I have been observing for twenty years in practice. Two different roads, the same conclusion. That is what gives me confidence in the approach, and it is all I take from it.

One more thing that matters: Lewis criticizes twelve-step programs. I don’t. I have seen those programs save lives, and if that is what works for you, keep going — sincerely. I offer something else, to people for whom something else is needed. This is not a competition.

And there is a real limit: none of this replaces a doctor. Physical withdrawal from alcohol or medication is done with medical supervision, not with a coach. If that is your situation, tell me: I will point you to the right place.

What else the method rests on

Three other sources that shape the program, each for a specific reason.

The neuroscience of habit

The mechanism

How a repeated response becomes automatic, and why it is reinstalled through repetition rather than through decision.

A stoic reading of perspective

The second movement

What depends on you, what doesn’t, and the fact that a belief can be confronted rather than endured.

Twenty years of direct practice

What books don’t say

I directed recovery centres, residential and outpatient, before building my own approach. The method comes from there first.

A thirty-minute conversation

An assessment call, free and confidential. We look at your situation, we identify what your behaviour is really solving, and I tell you honestly whether my program is the right place for you. If it isn’t, I say so.

This is not a sales call. It’s a conversation.
