Three centuries ago an inspired monk set forth his ideal of an ennobled world in _The City of the Sun_. Campanella wrote that prophetic book in prison. But his spirit was unfettered, and his conception of human society, though in daring it outruns all the visions we may compare it with, is yet on the lines along which our civilization lies. In the City of the Sun not only was the nobility of work, even mechanical work,--which Plato rejected and More was scarcely conscious of,--for the first time recognized, but the supreme impulse of procreation was regarded as a sacred function, to be exercised in the light of scientific knowledge. It was a public rather than a private duty, because it concerned the interests of the race; only valorous and high-spirited men ought to procreate, and it was held that the father should bear the punishments inflicted on the son for faults due to his failure by defects in generation.[23] Moreover, while unions not for the end of procreation were in the City of the Sun left to the judgment of the individuals alone concerned, it was not so with unions for the end of procreation. These were arranged by the "great Master," a physician, aided by the chief matrons, and the public exercises of the youths and maidens, performed in a state of nakedness, were of assistance in enabling unions to be fittingly made. No eugenist under modern conditions of life proposes that unions should be arranged by a supreme medical public official, though he might possibly regard such an official, if divested of any compulsory powers, a kind of public trustee for the race, as a useful institution. But it is easy to see that the luminous conception of racial betterment which, since Galton rendered it practicable, is now inspiring social progress, was already burning brightly three centuries ago in the brain of this imprisoned Italian monk. Just as Thomas More has been called the father of modern Socialism, so Campanella may be said to be the prophet of modern Eugenics.
