A State Health Service is not as new an institution as is generally supposed. It existed in the ancient world in Greek lands, and, perhaps in imitation, in the Roman West. While, of course, it cannot be said that the National Health Service of twentieth-century Britain was inspired by the practice of antiquity (which, indeed, was probably unknown to those who created it), the modern scheme constitutes a return to a view of the State which obtained in ancient times. The beneficent activity of the Church and then of privately supported hospitals mitigated the results of the disappearance of the ancient Welfare State. The evidence, scanty as it is, for the Health Service among the Greeks throws light on their attitude towards the proper function of the State as well as on their great appreciation of the skill and activity of the medical profession.
