We must as a paradigm doubt methodically (Descartes), if necessary even our own master (Bacon), to dedicate ourselves to the search for the correct diagnosis that will allow us with the greatest precision (Spinoza), to treat and solve in an adequate way the problem of our human patient, our problem. We must keep in mind the different types of prejudices so deeply rooted even today in our society that 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 approach the diagnosis that afflicts that being who approaches us for help. It is of vital importance to continuously observe man as a substantiated entity, unique, impossible to separate into two different things, although we can study them separately and divide them into two that will always be one as long as he exists as a man.

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