CHAPTER XII
From the time the law of Copernicus was discovered and proved, the mere recognition of the fact that it was not the sun but the earth that moves sufficed to destroy the whole cosmography of the ancients. By disproving that law it might have been possible to retain the old conception of the movements of the bodies, but without disproving it, it would seem impossible to continue studying the Ptolemaic worlds. But even after the discovery of the law of Copernicus the Ptolemaic worlds were still studied for a long time.
From the time the first person said and proved that the number of births or of crimes is subject to mathematical laws, and that this or that mode of government is determined by certain geographical and economic conditions, and that certain relations of population to soil produce migrations of peoples, the foundations on which history had been built were destroyed in their essence.
By refuting these new laws the former view of history might have been retained; but without refuting them it would seem impossible to continue studying historic events as the results of man’s free will. For if a certain mode of government was established or certain migrations of peoples took place in consequence of such and such geographic, ethnographic, or economic conditions, then the free will of those individuals who appear to us to have established that mode of government or occasioned the migrations can no longer be regarded as the cause.
And yet the former history continues to be studied side by side with the laws of statistics, geography, political economy, comparative philology, and geology, which directly contradict its assumptions.
The struggle between the old views and the new was long and stubbornly fought out in physical philosophy. Theology stood on guard for the old views and accused the new of violating revelation. But when truth conquered, theology established itself just as firmly on the new foundation.
Just as prolonged and stubborn is the struggle now proceeding between the old and the new conception of history, and theology in the same way stands on guard for the old view, and accuses the new view of subverting revelation.
In the one case as in the other, on both sides the struggle provokes passion and stifles truth. On the one hand there is fear and regret for the loss of the whole edifice constructed through the ages, on the other is the passion for destruction.
To the men who fought against the rising truths of physical philosophy, it seemed that if they admitted that truth it would destroy faith in God, in the creation of the firmament, and in the miracle of Joshua the son of Nun. To the defenders of the laws of Copernicus and Newton, to Voltaire for example, it seemed that the laws of astronomy destroyed religion, and he utilized the law of gravitation as a weapon against religion.
Just so it now seems as if we have only to admit the law of inevitability, to destroy the conception of the soul, of good and evil, and all the institutions of state and church that have been built up on those conceptions.
