"But we may fairly say that they alone are engaged in the true duties of life who shall wish to have Zeno, Pythagoras, Democritus, and all the other … - Giordano Bruno

If all things are in common among friends, the most precious is Wisdom. What can Juno give which thou canst not receive from Wisdom? What mayest thou admire in Venus which thou mayest not also contemplate in Wisdom? Her beauty is not small, for the lord of all things taketh delight in her. Her I have loved and diligently sought from my youth up.

Theophilo. Well said. But you do not answer the pith of the argument. For I do not insist on infinite space, nor is Nature endowed with infinite space for the exaltation of size or of corporeal extent, but rather for the exaltation of corporeal natures and species, because infinite perfection is far better presented in innumerable individuals than in those which are numbered and finite. Needs must indeed that there should be an infinite image of the inaccessible divine countenance and that there should be in this image as infinite members thereof, innumerable worlds, namely, these others that I postulate. But since innumerable grades of perfection must, through corporeal mode, unfold the divine incorporeal perfection, therefore there must be innumerable individuals, those great animals, whereof one is our earth, the divine mother who hath given birth to us, doth nourish us and moreover will receive us back; [19] and to contain these innumerable bodies there is needed an infinite space. Nevertheless it is well that there should be since there can be innumerable worlds similar to our own, even as our world hath achieved and doth achieve existence and it is well that it should exist.

Thus we on this our earth say that the earth is the center, and all the philosophers ancient and modern, of whatsoever sect, will say, this is the center, according to their own principles, just as we say, we are in the center of the great circular horizon of our own ethereal region, which remains a circular, equidistant boundary wherever we stand, so we regard ourselves as standing in the center. In the same way, those on the moon would with no less justification assume that they were in the center of their own horizon which encircles their land, and the sun and every other star will also believe they stand amidst the radii of their own horizon, but they are no more the center than is the earth or any of the other mundane spheres; and they are no more the certain poles than is the earth a certain pole for them; all are likewise, from different perspectives, each the center point of some circumference, and a pole, and a zenith for somewhere else. The earth, therefore, is not the absolute center of the universe, but only the center as seen from our location.
