In the twelfth century, a new spirit pervading all society gave the slave his rights, and through justice breathed new life into the heart of nations.
It has been said, and often repeated, that Christianity regenerated the world.

That is true; but it seems to me that there is a mistake in the date.

The patrician families became extinct, as the feudal families did, and as all aristocracies must.
It was in the middle ages, when a reactionary movement was beginning to secretly undermine accumulated property, that the influence of Christianity was first exercised to its full extent.
The destruction of feudalism, the conversion of the serf into the commoner, the emancipation of the communes, and the admission of the Third Estate to political power, were deeds accomplished by Christianity exclusively.
