"I do not ... reject the use of statistics in medicine, but I condemn not trying to get beyond them and believing in statistics as the foundation of medical science. ... Statistics ... apply only to cases in which the cause of the facts observed is still [uncertain or] indeterminate. ... There will always be some indeterminism ... in all the sciences, and more in medicine than in any other. But man's intellectual conquest consists in lessening and driving back indeterminism in proportion as he gains ground for determinism by the help of the experimental method."

There may have been somewhere, as a few eighteenth-century philosophers dreamed, a group of peaceful men who got together one evening after work and drew up a Social Contract to form the state. But nobody has been able to find an actual record of it. Practically all the governments whose origins are historically established were the result of conquest-of one tribe by another, one city by another, one people by another. Of course there have been constitutional conventions, but they merely changed the working rules of governments already in being.
