The fecundity of a people sometimes depends on the smallest circumstances in the world, so that it often requires no more than a new turn in one’s imagination to make it much more numerous that it was.
The Jews, forever exterminated and forever rebounding, have restored their continual losses and continual destructions by this single hope that all families have among them of seeing born to them a powerful king who will be master of the world.

On the other hand the Muhammadan countries become more empty by the day because of an opinion which, holy as it is, still has very pernicious effects when it is rooted in the minds. We see ourselves as travellers who should think only of another homeland ; useful and durable works, cares to assure the fortune of our children, and projects that tend beyond a short and transient life, appear to us as something extravagant.
