"<p>Ideas, without a doubt, shoot forth with the force with which they arise, and strike where the mind sends them, according to a kind of mathematical law that governs a bullet fired from a mortar. But ideas work in different ways. If they nestle themselves in gentle natures, they rage and destroy there. On the other hand, there are strongly bloodied natures, ore-walled skulls, on which the alien will flattens and falls like a bullet from a stone bastion. Then there are flabby, cotton-wool natures in which other people's ideas are lost, just as bullets sink into the soft soil of a castle rampart.</p>"
