The bravest mob of independent fighters has little chance against a handful of disciplined soldiers, and the Church is perfectly logical in seeing her chief danger in the Encyclopaedia's systematised marshalling of scattered truths. As long as the attacks on her authority were isolated, and as it were sporadic, she had little to fear even from the assaults of genius; but the most ordinary intellect may find a use and become a power in the ranks of an organised opposition. Seneca tells us the slaves in ancient Rome were at one time so numerous that the government prohibited their wearing a distinctive dress lest they should learn their strength and discover that the city was in their power; and the Church knows that when the countless spirits she has enslaved without subduing have once learned their number and efficiency they will hold her doctrines at their mercy. --
