It is the same with the mass of mankind, who not individually, but always in a mass, under the influence of a new social idea pass all at once from one organization of life to another. This mass always hinders, by its inertia, frequent and rapid revolutions in the social order which have not been sufficiently proved by human experience. And it delays every truth a long while till it has stood the test of prolonged struggles, and has thoroughly permeated the consciousness of humanity.

And that is why it is a mistake to say that because only a very small minority of men has assimilated Christianity in eighteen centuries, it must take many times as many centuries for all mankind to assimilate it, and that since that time is so far off we who live in the present need not even think about it.
