In Switzerland, Theophrastus Paracelsus, an astrologer and alchemist who later became a physician, did not believe that humor imbalance caused disease nor in treatment by blood-letting or purging. He believed that there were external causes of disease, e.g. toxic matter in food, contagion, defective physical or mental constitution, cosmic influences differing with climate and country, or affliction sent Providence. He urged that wounds be kept clean rather than given poultices. He started clinical diagnosis and treatment by highly specific medicines, instead of cure-alls. For instance, he used alkalies to treat disease, such as gout, indicated by certain substances in the urine, which also started urinalysis. He perceived that syphillis was caused by contagion and used mercury to cure it. He found curative powers also in opium, sulphur, iron, and arsenic. Opium was made by drying and cooking the capsule of the poppy and was one of the few really effective early drugs. Paracelsus urged alchemists to try to prepare drugs from minerals for the relief of suffering. He claimed to acquire knowledge of cures through spiritual contacts to occult wisdom. He believed that a human being has an invisible body as well as a visible one and that it is closely attuned to imagination and the spiritual aspect of an individual. He noticed that one's attitudes and emotions, such as anger, could affect one's health. He sometimes used suggestion and signs to help a patient form mental images, which translated into cures. He saw insanity as illness instead of possession by evil spirits.
Understanding of the celestial world began to change. Contemporary thought was that the nature of all things was to remain at rest, so that movement and motion had to be explained by causes. The earth was stationary and the heavens were spherical and revolved around the earth every twenty-four hours. The universe was finite. The firmament extended outward in a series of rotating, crystalline, ethereal spheres to which were attached the various points of celestial geography. First came the circle of the moon. The sun orbited the earth. The fixed stars rotated on an outer firmament. Finally, there was the abode of God and his heavenly hosts. Different principles ruled the celestial world; it was orderly, stable, ageless, and enduring. But the world of man changed constantly due to its mixed four elements of air, earth, fire, and water each trying to disentangle itself from the others and seeking to find its natural location. The heavenly spheres could affect the destinies of men, such as through fate, fortune, intelligence, cherubim, seraphim, angels, and archangels. Astrologers read the celestial signs and messages.
Then a seed of doubt was cast on this theory by Nicholaus Copernicus, a timid monk in Poland, who found inconsistencies in Ptolemy's work, but saw similarity in the movements of the earth and other planets. He inferred from planetary movements that their motion could be explained simply if they were revolving in circular paths around the sun, rather than around the earth. In his book of 1543, he also expressed his belief that the earth also revolved around the sun. This idea so shocked the world that the word "revolution" became associated with radical change. He regarded it as more likely that the earth rotated than that the stars moved with great speed in their large orbits. He proposed that the earth spins on its own axis about once every twenty-four hours, with a spin axis at about a 23 1/2 degree tilt from the orbital axis, thus explaining a slow change in the overall appearances of the fixed stars which had been observed since the time of Ptolemy. He deduced from astronomical measurements that the correct order of the planets from the Sun was: Mercury, Venus, Earth, Mars, Jupiter, and Saturn. The church considered his ideas heretical because contradictory to its dogma that man and the earth were the center of the universe. A central sun evoked images of pagan practices of sun worship.
- The Law -
A person having land in socage or fee simple may will and devise his land by will or testament in writing.
A person holding land by knight's service may will and devise by his last will and testament in writing part of his land to his wife and other parts of his land to his children, as long as 1/3 of entailed land is left to the King.
Anyone serving the king in war may alienate his lands for the performance of his will, and if he dies, his feoffees or executors shall have the wardship of his heir and land.
A person who leases land for a term of years, even if by indenture or without a writing, may have a court remedy as do tenants of freehold for any expulsion by the lessor which is contrary to the lease, covenant, or agreement. These termers, their executors and assigns, shall hold and enjoy their terms against the lessors, their heirs and assigns. The lessor shall have a remedy for rents due or waste by a termer after recovering the land as well as if he had not recovered the land.
A lord may distrain land within his fee for rents, customs, or services due without naming the tenant, because of the existence of secret feoffments and leases made by their tenants to unknown persons.
Anyone seised of land to the use or trust of other persons by reason of a will or conveyance shall be held to have lawful seisin and possession of the land, because by common law, land is not devisable by will or testament, yet land has been so conveyed, which has deprived married men of their courtesy, women of their dower, the king of the lands of persons attainted, the king of a year's profits from felons' lands, and lords of their escheats. (This was difficult to enforce.)
