I've been in many of them and to some extent I would have to say this: If you've seen one city slum you've seen them all.
If Nature denies eternity to beings, it follows that their destruction is one of her laws. Now, once we observe that destruction is so useful to her that she absolutely cannot dispense with it from this moment onward the idea of annihilation which we attach to death ceases to be real what we call the end of the living animal is no longer a true finish, but a simple transformation, a transmutation of matter. According to these irrefutable principles, death is hence no more than a change of form, an imperceptible passage from one existence into another.
Wolves which batten upon lambs, lambs consumed by wolves, the strong who immolate the weak, the weak victims of the strong: there you have Nature, there you have her intentions, there you have her scheme: a perpetual action and reaction, a host of vices, a host of virtues, in one word, a perfect equilibrium resulting from the equality of good and evil on earth.
