It is certain that the labors of these early workers in the field of natural knowledge were brought to a standstill by the decay and disruption of the Roman Empire, the consequent disorganisation of society, and the diversion of men's thoughts from sublunary matters to the problems of the supernatural world suggested by Christian dogma in the Middle Ages. And, notwithstanding sporadic attempts to recall men to the investigation of nature, here and there, it was not until the fifteenth and sixteenth centuries that physical science made a new start, founding itself, at first, altogether upon that which had been done by the Greeks. Indeed, it must be admitted that the men of the Renaissance, though standing on the shoulders of the old philosophers, were a long time before they saw as much as their forerunners had done.
Up till now it has been thought that the growth of the Christian myths during the Roman Empire was possible only because printing was not yet invented. Precisely the contrary. The daily press and the telegraph, which in a moment spreads inventions over the whole earth, fabricate more myths (and the bourgeois cattle believe and enlarge upon them) in one day than could have formerly been done in a century.
