Book I, Chapter VI
And as the part is to the whole, so is the order of parts to the order of the whole. The part is to the whole, as to an end and highest good which is aimed at; and, therefore, the order in the parts is to the order in the whole, as it is to the end and highest good aimed at. Hence we have it that the goodness of the order of parts does not exceed the goodness of the order of the whole, but that the converse of this is true. Therefore we find a double order in the world, namely, the order of parts in relation to each other, and their order in relation to some one thing which is not a part (as there is in the order of the parts of an army in relation to each other, and then in relation to the general); and the order of the parts in relation to the one thing which is not a part is the higher, for it is the end of the other order, and the other exists for the sake of it. Therefore, if the form of this order is found in the units of the mass of mankind, much more may we argue by our syllogism that it is found in mankind considered as a whole; for this latter order, or its form, is better. But as was said in the preceding chapter, and it is sufficiently plain, this order is found in all the units of the mass of mankind. Therefore it is, or should be, found in the mass considered as a whole. And therefore all the parts that we have mentioned, which are comprised in kingdoms, and the kingdoms themselves ought to be ordered with reference to one Prince or Princedom, that is, with reference to a Monarch or Monarchy.
