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.
