When we talk about the clinic of delusional symptoms, we are first and foremost affirming that delusions exist. Professionals working in psychiatry know that delusions can be listened to, that they give meaning to suffering and are part of the history of the subject. Taking the time to reflect on this type of symptom allows us to invest in the clinical field specific to psychiatry, and only makes sense if the clinical approach is based on work referring to the patient's individual history. Maintaining and developing these attitudes to care is essential to the survival of psychiatry as a discipline. Focusing on the clinic of delusion is neither a luxury nor a waste of time.
