Antique religion and antique medicine had effected a reconciliation—a reconciliation, however, in which neither party was to acknowledge a complete defeat; but the result was an amicable settlement, in which their just dues were given both to the theistic and to the physico-mechanical theories of life. The point of agreement upon which this settlement, or, to express it better, compromise, was made was teleology. By teleology we understand the conception that all earthly existence is created by a supreme power in accordance with a preconceived plan, and that, accordingly, all organic life, in form and action, is most perfectly adapted to the task prescribed for it by this power. This conception was absolutely indispensable to antique medicine; for it allowed the adherents of the theistic theory without hesitation to consider man as a product of the creator, which was distinguished in all directions and which bore witness of the wisdom of God, a position which precluded the assumption, which was impossible according to the antecedent medical observations, that disease came from God. For it seemed quite plausible, according to the physico-mechanical theory of life, that disease might be a product of a number of adverse, purely earthly conditions, an assumption not involving the slightest doubt of the wisdom and creative power of the gods. This teleological doctrine, which runs like a red thread through all ancient philosophy, becomes conspicuously prominent in Galen. Every section of the powerful work of Galen—anatomy, as well as physiology, pathology, and therapy—bear witness to the most confident teleological conception, a conception which in the end culminates in the verdict (“Use of the Parts,” Book 11, Chapter XIV.): “The creator of nature has disclosed his benevolence by wise care for all his creatures, in that he has bestowed upon each one what is truly of service to it.”
