Once a disease has entered the body, all parts which are healthy must fight it: not one alone, but all. Because a disease might mean their common death. Nature knows this and Nature attacks the disease with whatever help she can muster. – Paracelsus

Say not that honor is the child of boldness, nor believe thou that the hazard of life alone can pay the price of it: it is not to the action that it is due, but to the manner of performing it. – Akhenaton
