At present, Prussia has done nothing beyond enlarging this system, and at the same time stamping it more powerfully with a poetical and philosophical tendency; for the ideas and impressions of stormy and difficult times are not required in calmer seasons. Prussia appears likely to realise the problem of an intelligent people, highly advanced in philosophical knowledge, and yet capable of doing without what are called constitutional institutions. The idea that proposes to centralise and confound every thing, the visionary desire that would group Germany around the cathedral of Cologne, is grand and vast; but, in order this unity should triumph, would not the first necessary condition be, that there should be but one faith, one object of love, one system of belief? And how can Protestantism, which is so constantly subject to internal dissensions, create unity? To make Berlin the capital of science, to cause all the universities to converge towards that point, as to an Athens dreamed of by the philosophers, is a noble idea of the government; but, on the other hand, what means this license against Christianity? Though Frederic the Great received Atheists privately at his table, he would never have permitted atheism to be publicly taught; and an empire desirous of seeking for unity in science and philosophy must lay the first foundations in religion and Christian instruction. My opinion, then, is, that the Romish system can alone form a powerful bond among the people; otherwise, Cologne restored will only present a barren proof of the utter incapacity of Protestantism to renew the Catholic union of the arts and religion, as it existed during the middle ages.
