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.
