4. According to Galen's long-dominant explanation of the four humors, human illness was caused primarily by:
Answer: B
Human illness was caused primarily by an excess of a particular bodily fluid.
Galen's theory posited that imbalances in the four humors—blood, phlegm, yellow bile, and black bile—were the primary causes of human illness. Thus, an excess of any one of these bodily fluids would lead to different health issues.
A) divine anger
This option is incorrect because Galen's framework did not attribute illness to divine anger. Instead, his focus was on the physiological aspects of the body, particularly the balance of humors, rather than metaphysical or divine causes.
B) an excess of a particular bodily fluid
This is the correct answer as it directly aligns with Galen's explanation of illness. He argued that each humor's balance was crucial for health, and an excess of one could lead to disease, making this a foundational concept in his medical theory.
C) prolonged periods of melancholy
While melancholy can be associated with an imbalance of humors, it is not a primary cause of illness according to Galen. Instead, it is one of the potential outcomes resulting from the excess of black bile, which is just one of the four humors.
D) contact with one of the four elements making up the material world
This option is incorrect because Galen's theory was not centered on elemental interactions but rather on the internal balance of bodily fluids. The four elements (earth, water, air, fire) were not the focus of his explanations for illness.
E) the movement of the stars and planets
Galen did not attribute illness to astrological influences. Although some ancient medical practices considered astrology, Galen's approach emphasized human biology and the humors over celestial movements.
Conclusion
In summary, the correct answer is that illness, according to Galen, was primarily caused by an excess of a particular bodily fluid. This understanding of the four humors serves as a crucial aspect of his medical philosophy, distinguishing it from other explanations that focus on divine, elemental, or astrological factors. All other options fail to encapsulate the central role of bodily fluids in his theory of health and disease.
