Galen learned from doctors such as Hippocrates about the four humors.
Hippocrates, a greek doctor, in 460-377 BC
Hippocrates believed that the human body was controlled by four humors, phlegm, black bile, yellow bile and blood. Illnesses were caused by an imbalance of the humors.
Aristotle did not specifically link to the theory of the four humours; that theory was developed by ancient Greek physician Hippocrates. The theory of the four humours was based on a belief that four bodily fluids (blood, phlegm, yellow bile, black bile) influenced a person's health and temperament. Aristotle's work focused more on philosophy, science, and ethics rather than medicine.
According to Hippocrates the theories of disease causation are the 4 humors, blood, phlegm, yellow and black bile.
Four of them.
Hippocrates was a Greek man who lived with his father who taught him about medicine. He grew up to figure out a method called the four humors. This was where one of the four humors (phlegm, black bile, yellow bile or blood) would be out of balance and he would use different methods to put them into balance. His ideas were developed further through time, and this is the main reason why Hippocrates became famous. Another thing that interested people on Hippocrates was the fact he made the Hippocratic Oath. This was where a doctor or surgeon must read from the Oath before performing surgery, to swear they were performing the surgery for the good of the others and the good of god, and not of that for their money rise.
Four of them.
Hippocrates was the first physician to treat diseases as the result of living habits rather than a punishment by the gods. The Hippocratic school believed that all illnesses were the result of an imbalance in the body of the four humours, fluids that when in health were naturally equal in amount. The four humours are, blood, black bile, yellow bile and phlegm. Hippocrates recommended that a physician was to always be tidy, honest, calm, understanding and serious.
The first and third lines of "The Haunted Oak" by Paul Laurence Dunbar both have 7 stressed syllables each.
The word "organization" has four syllables: or-ga-ni-za-tion. The stressed syllable, where the emphasis falls, is on the third syllable, "ni." So, it is pronounced as or-ga-NI-za-tion.
Anything minus itself is zero.
