| 143. Servetus as a Physician, Scientist, and Astrologer. | ||||
Being supplied with the necessary funds, Servetus returned to Paris in 1536 and took his degrees as magister and doctor of medicine. He acquired great fame as a physician. | ||||
The medical world was then divided into two schools, the Galenists, who followed Hippocrates and Galen, and the Averrhoists, who followed Averrhoes and Avicenna. Servetus was a pupil of Champier, and joined the Greek school, but had an open eye to the truth of the Arabians. | ||||
He published in 1537 a learned treatise on Syrups and their use in medicine. It is his most popular book, and passed through four editions in ten years. | ||||
He discovered the pulmonary circulation of the blood or the passage of the blood from the right to the left chamber of the heart through the lungs by the pulmonary artery and vein. He published it, not separately, but in his work on the Restitution of Christianity, as a part of his theological speculation on the vital spirits. The discovery was burnt and buried with this book; but nearly a hundred years later William Harvey (1578-1658), independently, made the same discovery. | ||||
Servetus lectured in the University on geography and astrology, and gained much applause, but excited also the envy and ill-will of his colleagues, whom he treated with overbearing pride and contempt. | ||||
He wrote an Apologetic Dissertation on Astrology, and severely attacked the physicians as ignoramuses, who in return denounced him as an impostor and wind-bag. The senate of the University sided with the physicians, and the Parliament of Paris forbade him to lecture on astrology and to prophesy from the stars (1538). | ||||
He left Paris for Charlieu, a small town near Lyons, and practised medicine for two or three years. | ||||
At his thirtieth year he thought that, after the example of Christ, he should be rebaptized, since his former baptism was of no value. He denied the analogy of circumcision. The Jews, he says, circumcised infants, but baptized only adults. This was the practice of John the Baptist; and Christ, who had been circumcised on the eighth day, was baptized when he entered the public ministry. The promise is given to believers only, and infants have no faith. Baptism is the beginning of regeneration, and the entrance into the kingdom of heaven. He wrote two letters to Calvin on the subject, and exhorted him to follow his example. | ||||
His arrogance made him so unpopular that he had to leave Charlieu. | ||||
