To prevent such a state of affairs, Marx advised working men of all countries to unite and to fight for a number of political and economic measures which he had enumerated in a Manifesto in the year 1848, the year of the last great European revolution.

These views of course were very unpopular with the governments of Europe, many countries, especially Prussia, passed severe laws against the Socialists and policemen were ordered to break up the Socialist meetings and to arrest the speakers. But that sort of persecution never does any good. Martyrs are the best possible advertisements for an unpopular cause. In Europe the number of socialists steadily increased and it was soon clear that the Socialists did not contemplate a violent revolution but were using their increasing power in the different Parliaments to promote the interests of the labouring classes. Socialists were even called upon to act as Cabinet Ministers, and they co-operated with progressive Catholics and Protestants to undo the damage that had been caused by the Industrial Revolution and to bring about a fairer division of the many benefits which had followed the introduction of machinery and the increased production of wealth.

THE AGE OF SCIENCE

BUT THE WORLD HAD UNDERGONE ANOTHER CHANGE WHICH WAS OF GREATER IMPORTANCE THAN EITHER THE POLITICAL OR THE INDUSTRIAL REVOLUTIONS. AFTER GENERATIONS OF OPPRESSION AND PERSECUTION, THE SCIENTIST HAD AT LAST GAINED LIBERTY OF ACTION AND HE WAS NOW TRYING TO DISCOVER THE FUNDAMENTAL LAWS WHICH GOVERN THE UNIVERSE

THE PHILOSOPHER

The Egyptians, the Babylonians, the Chaldeans, the Greeks and the Romans, had all contributed something to the first vague notions of science and scientific investigation. But the great migrations of the fourth century had destroyed the classical world of the Mediterranean, and the Christian Church, which was more interested in the life of the soul than in the life of the body, had regarded science as a manifestation of that human arrogance which wanted to pry into divine affairs which belonged to the realm of Almighty God, and which therefore was closely related to the seven deadly sins.
