Although the envy of other physicians at Rome and their accusing him of resort to magic arts and divination in his marvelous prognostications and cures were perhaps neither the sole nor the true reason for Galen’s temporary withdrawal from the capital, there probably is a great deal of truth in the picture he paints of the medical profession and learned world of his day. There are too many other ancient witnesses, from the encyclopedist Pliny and the satirist Juvenal to the fourth century lawyer and astrologer, Firmicus, who substantiate his charges to permit us to explain them away as the product of personal bitterness or pessimism. We feel that these men lived in an intellectual society where faction and villainy, superstition and petty-mindedness and personal enmity, were more manifest than in the quieter and, let us hope, more tolerant learned world of our time. Selfishness and pretense, personal likes and dislikes, undoubtedly still play their part, but there is not passionate animosity and open war to the knife on every hand. The _status belli_ may still be characteristic of politics and the business world, but scholars seem able to live in substantial peace. Perhaps it is because there is less prospect of worldly gain for members of the learned professions than in Galen’s day. Perhaps it is due to the growth of the impartial scientific spirit, of unwritten codes of courtesy and ethics within the leading learned professions, and of state laws concerning such matters as patents, copyright, professional degrees, pure food, and pure drugs. Perhaps, in the unsatisfactory relations between those who should have been the best educated and most enlightened men of that time we may see an important symptom of the intellectual and ethical decline of the ancient world.
