As a paradigm, we must methodically doubt (Descartes), if necessary, even from our own teacher (Bacon), in order to devote ourselves to the search for the correct diagnosis that will allow us with the greatest precision (Spinoza), to adequately treat and solve the problem of our human patient, our problem. We must bear in mind the different types of prejudices that are so deeply rooted in our society today that they threaten the development of the sciences.

It will be necessary to keep ourselves in the constant search for the truth in order to try to get closer to the diagnosis that afflicts that being who approaches us for help. It is vitally important to continually observe man as a substantiated, unique entity, impossible to separate into two different things, although we may study them separately and divide him into two which will always be one as long as he exists as a man.

The analysis of the patient's ordinary language for the physician will be of great use in an attempt to minimize diagnostic error in medical semiology. Conversation humanizes the relationship between two individuals who are fundamentally different, the doctor and the patient.
