Michael Servetus, the pneumatic mind.

Servetus exhibits in his thesis that "air spirit" (air) is carried by blood from lungs to heart and brain, the same that happened in that the original divine inspiration, the Creation one, the Genesis one, says Servetus. Hence every new inspiration and ulterior illumination stimulates that. In each inspiration “pneuma” or “spirit” enters the lungs. This air, by blood circulation, illuminates the mind when arrives to brain, continuously, blow to blow, breath to breath. Soul quality depends, at structural explanation, on conformation and disposition of blood vessels in the brain, recognized Servet. At the functional level, however, depends on the quality of “spirit” that enters these vessels. Servetus speaks of bad spirits and good spirits acting in the cavities of the ventricles of the brain. And as pointed out A. Alcalá, with bad spirit Servetus do not mean "evil spirit" or “demon”, but simply notes that the "spirit" (air) can be physiologically and mental…

Michael Servetus, the mechanism.

The most recognized contribution of Servetus to science is the first description of minor circulation of blood, which exposes in his work The first description of blood circulation. It is recognized a great value to, totally deserved, since it was not known at the time the existence of pulmonary circulation of blood. This writing is an excellent lesson in anatomy and physiology of the moment. But to Servetus it was not an exclusive anatomical and physiological matter but much more, as he always expressed. What Servetus really intended was to make a "divine philosophy" that meets "the complete knowledge of the soul and of the spirit". The discovery of the pulmonary circulation of the blood means to him the empirical understanding of the functioning mechanism of “soul” and “human spirit”. In Latin spiritus, and the Greek pneuma, mean, on the physical plane, air, and also breath or blow, and even what we now understand as wave or vibration. On a philosophical level the…
