That there are more worlds than one is due to the presence everywhere throughout space of the same principle of life, which everywhere has the same effect; just as within one of these worlds, the earth, we find different species of the same animal--of man, for example--which cannot be descended from the same parentage. There are "men of different colours, cavemen, mountain-pygmies, the guardians of minerals, the giants of the South," each of which races must have been produced independently in its own place. And finally, although it is true that nothing can be added to the perfect, why may not the perfect be multiplicable? Though the perfect man is one, nature may produce several within the same species. "Everywhere is one soul, one spirit of the world, wholly in the whole and in every part of it, as we find in our lesser world also. This soul ... (should the kind of place and of element not conflict) produces all things everywhere; so that for the generation of some even time is not required.... The infinite universe, and it only under God, is perfect. Nothing finite is so good that it could not be better; whatever may be better has some degree of evil and defect, as what is not absolutely bright is not without some signs of obscurity.... Therefore the perfect, absolutely and in itself, is one, infinite, which cannot be greater or better, and than which nothing can be greater or better. This is one, everywhere, the only God, universal nature, of which nothing can be a perfect image or reflection, but the infinite. Everything finite therefore is imperfect, every sensible world is imperfect, as good and evil, matter and form, light and darkness, joy and sadness concur in it, and all things everywhere are in alteration and movement; but all of them, in the infinite, are as in unity, truth, and goodness, and in this aspect the infinite is rightly called the universe."[332] In the infinite, as we have learned from the _Causa_, all contraries are one. The universe is perfect, not because of its quantity, but because it contains all other things in it.[333] Within the limits of their kind small causes can produce small effects with some perfection; much more effective is that immeasurable and more general cause, of which nothing stands in the way. It is a harmony of the many in one, the only corporeal image of the divine mind. The finite, however, is imperfect only when taken apart from the whole to which it belongs, _i.e._ evil and defect are appearances only. Although in nature not all things are of their best, and more species than one produce monstrosities, yet we may not find fault with the great building of the mighty architect, for even the small, weak, and diminutive contributes its part to the nobility of the whole. Is a picture most beautiful when it is blazoned all over with gold and purple? Does it not shine out best from a dull background? Can there be any part which, in its order and place within the whole
