The philosophical case

The book sits at the intersection of critical realism, phenomenology, and the philosophy of psychiatry. It draws on Bhaskar’s stratified ontology, Margaret Archer’s morphogenetic approach, Merleau-Ponty on the lived body, Arendt on the ethics of recognition, and Foucauldian analyses of governmentality and stigma — and uses them to read the institutional failure of co-occurring mental health and substance use care.

The central move is from epistemology to ontology: dual-diagnosis frameworks fail not because we measure the wrong things, but because we have inherited categories that cannot describe what is actually there.

  • Suggested chapters to start: 2 (false stories), 3 (epistemic injustice), 6 (morphogenetic failure), 8 (the model).
  • Reading group guide and seminar discussion questions in Resources.
  • Citations & bibliography available as a downloadable BibTeX/RIS file.

What this means in the room

If you commission services, line-manage frontline teams, or work directly with people whose distress and substance use are entangled, this book is an attempt to name what you already know: the system is not broken in the way you’ve been told. It is built this way.

The Layered Care Model is the practical core. Four pillars, an operational logic of practising rather than perfecting, and a measurement principle — completion is not the point; return is — that gives commissioners something defensible to fund.

  • Suggested chapters: 1 (the scale), 7 (beyond dual diagnosis), 8 (the model), 10 (structural reform and policy shifts).
  • Briefing pack for commissioners — one-page summary, four-pillar diagram, sample service specification language. Download.
  • Speaking & in-house training available — see Talks & Press.

If you’ve been on the wrong side of these systems

This book was written, in part, for you. It tries to say in the language of philosophy what people with lived experience have been saying in plainer terms for a long time: pain comes first. Drugs come later. The story that puts the substance before the suffering is the wrong story, and it has shaped almost everything about how services see — or refuse to see — you.

You will not find your story being explained away here. The chapters draw on real accounts (with names and details changed) and treat survival strategies — including substance use — as intelligible responses to unbearable conditions, not character defects.

  • Plain-language summary of the central argument, available as a free PDF in Resources.
  • If you took part in the research that underpins the doctoral work behind this book — thank you. The acknowledgements name that debt directly.
  • Content note: the book discusses self-harm, overdose, bereavement, prison, and homelessness in a clinical and analytical register. Take it at your own pace.
