[The place of consent in relationships between physicians and patients: a philosophical point of view].

In the past, doctors did not hesitate to impose their point of view to patients. Today, informing patients and obtain their consent is the norm. But the patient is really in a position to make a decision about his health, when in a vulnerable situation? Which are the limits of informed consent? Does exist a link between the ability that everyone has to self-determination (autonomy), and the specific choices that we have to do when we are sick? We offer a philosophical approach on the relationship between autonomy, freedom and consent in the context of relations between doctors and patients.
