Q. Why are the sensible powers in the heart; yet if the hinder part of the brain be hurt, the memory suffereth by it; if the forepart, the
imagination; if the middle, the cogitative part? A. It is because the brain is appointed by nature to cool the blood of the heart; whereof it is, that in divers of its parts it serveth the powers and instruments with their heart, for every action of the soul doth not proceed from one measure of heat.
THE PROBLEMS OF
ALEXANDER APHRODISEUS
Q. Why doth the sun make a man black and dirt white, wax soft and dirt hard? A. By reason of the disposition of the substance that doth suffer. All humours, phlegm excepted, when heated above measure, do seem black about the skin; and dirt, being full either of
saltpetre, or salt liquor, when the sun hath consumed its dregs and filth, doth become white again. When the sun hath stirred up and drawn the humidity of the wax, it is softened; but in the dirt, the sun doth consume the humidity, which is very much and makes it hard.
Q. Why are round ulcers hard to be cured? A. Because they are bred of a sharp choler, which eats and gnaws; and because it doth run, dropping and gnawing, it makes a round ulcer; for which reason it requires dry medicines, as physicians assert.
Q. Why is honey sweet to all men, but to such as have jaundice? A. Because they have much bitter choler all over their bodies, which abounds in the tongue; whence it happens when they eat honey the humours are stirred, and the taste itself, by the bitterness of choler, causes an imagination that the honey is bitter.
Q. Why doth water cast on serpents, cause them to fly? A. Because they are dry and cold by nature, having but little blood, and therefore fly from excessive coldness.
