one of your erudition. I will tell you in as few words as possible. I have only to call your attention to certain facts. To instruct you would be presumption.
The philosopher Plato, in his glorious work, the Timaeus, sets forth with more than mortal eloquence the constitution of the whole universe. After discoursing with great insight on the three powers that make up man's soul, and showing with the utmost clearness the divine purpose that shaped our various members, he treats of the causes of all diseases under three heads. The first cause lies in the elements of the body, when the actual qualities of those elements, moisture and cold and their two opposites, fail to harmonize. That comes to pass when one of these elements assumes undue proportions or moves from its proper place. The second cause of disease lies in the vitiation of those components of the body which, though formed out of the simple elements, have coalesced in such a manner as to have a specific character of their own, such as blood, entrails, bone, marrow, and the various substances made from the blending of each of these. Thirdly, the concretion in the body of various juices, turbid vapours, and dense humours is the last provocative of sickness.
Of these causes that which contributes most to epilepsy, the disease of which I set out to speak, is a condition when the flesh is so melted by the noxious influence of fire as to form a thick and foaming humour. This generates a vapour, and the heat of the air thus compressed within the body causes a white and eruptive ferment. If this ferment succeeds in escaping from the body, it is dispersed in a manner that is repulsive rather than dangerous. For it causes an eczema to break out upon the surface of the skin of the breast and mottles it with all kinds of blotches. But the person to whom this happens is never again attacked with epilepsy, and so he rids himself of a most sore disease of the spirit at the price of a slight disfigurement of the body. But if, on the other hand, this dangerous corruption[16] be contained within the body and mingle with the black bile, and so run fiercely through every vein, and then working its way upwards to the head flood the brain with its destructive stream, it straightway weakens that royal part of man's spirit which is endowed with the power of reason and is enthroned in the head of man, that is its citadel and palace. For it overwhelms and throws into confusion those channels of divinity and paths of wisdom. During sleep it makes less havoc, but when men are full of meat and wine it makes its presence somewhat unpleasantly felt by a choking sensation, the herald of epilepsy. But if it reaches such strength as to attack the heads of men when they are wide awake, then their minds grow dull with a sudden cloud of stupefaction and they fall to the ground, their bodies swooning as in death, their spirit fainting within them. Men of our race have styled it not only the 'Great sickness' and the 'Comitial sickness', but also the 'Divine sickness', in this resembling the Greeks, who call it [Greek: hiera nosos], the holy sickness. The name is just; for this sickness does outrage to the rational part of the soul, which is by far the most holy.
