39. But a good many, enticed by the fairness and brightness of the constellations, have in their blindness fallen into the errors of the stars, so that they endeavor to foreknow future events by the noxious computations that are called mathesis; but not only the teachers of the Christian religion, but also Plato and Aristotle and others of the heathen, moved by truth, condemned them with unanimous opinion, saying that confusion as to [future] things was produced rather from such a belief.
40. For if, as they say, men are driven by the compulsion of their birth to various kinds of acts, why should the good deserve praise, or the evil feel the vengeance of the law....
41. This succession of the seven secular disciplines was terminated in astronomy by the philosophers for this purpose forsooth, that it might free souls, entangled by secular wisdom, from earthly matters, and set them at meditation upon the things on high.
BOOK IV
ON MEDICINE[276]
INTRODUCTION
The Greek science of medicine was one which reached a high degree of development. As early as the fifth century B.C. it appears in the school of Hippocrates, divested of nearly all trace of its origin in superstition and magic, and largely relying on careful observation and interpretation of symptoms. This school already possessed a considerable body of recorded observations. At Alexandria, later, further progress was made, especially in the subject of anatomy. At this time the dissection—and even vivisection—of the human body was practiced, though there are few traces of it earlier, and later it was forbidden. The last great land-mark in the history of ancient medicine is to be found in the works of Galen (second century A.D.) who summed up, extended, and interpreted the medical knowledge of preceding times.
In medicine, however, as in Greek science generally, theoretical and philosophical elements often prevailed to the detriment of the pragmatical. Examples of this are to be seen in the theory of the four humors, first found in the Hippocratic writings; in the belief of the Methodist school, which held that disease consisted in the contraction and relaxation of the pores (πόροι); and in the doctrines of the Pneumatic school, which maintained that health and disease resulted from the influence of the universal soul (πνεῦμα). A reaction against this tendency is evidenced by the empirics, who professed to reject all general notions and to rely on experience alone. However, the increasing predominance of the theoretical is shown in the case of Galen, who secured his ascendency over succeeding ages by his extravagant theoretical system rather than by his really great practical knowledge.
No contribution to medicine was made by the Romans. Although the profession appeared among them in the second century B.C., it remained a thing apart, in the hands of Greek physicians.[277] Of the three chief writers on the subject in the Latin language, two, Celsus and Pliny, were not physicians but encyclopedists, who were necessarily compilers rather than scientists.[278] The only writer of importance who approached his work from a professional standpoint was Caelius Aurelianus, and his book is of importance chiefly because its Greek original is lost.[279] This neglect of medicine is explained in part by the fact that physicians stood low in the social scale. Another more powerful influence was the increasing fashionableness of Oriental religions with their superstition and addiction to magic practices. Toward the close of the empire the decline was rapid in medicine as in other fields. Abridgements, which cut down quality unconsciously as much as they did quantity consciously, held the field. Itinerant quacks and “folk-medicine” gradually ousted the lay profession until finally what little science remained was in the hands of priests and monks, who needed a smattering of the subject for the people of their parishes, and the inmates of monasteries and hospitals.[280]
