Theophilo. To come then to the discovery of that which we seek. I say that if in the first efficient Cause there be infinite power, there is also act… - Giordano Bruno

The fools of the world have been those who have established religions, ceremonies, laws, faith, rule of life. The greatest asses of the world are those who, lacking all understanding and instruction, and void of all civil life and custom, rot in perpetual pedantry; those who by the grace of heaven would reform obscure and corrupted faith, salve the cruelties of perverted religion and remove abuse of superstitions, mending the rents in their vesture. It is not they who indulge impious curiosity or who are ever seeking the secrets of nature, and reckoning the courses of the stars. Observe whether they have been busy with the secret causes of things, or if they have condoned the destruction of kingdoms, the dispersion of peoples, fires, blood, ruin or extermination; whether they seek the destruction of the whole world that it may belong to them: in order that the poor soul may be saved, that an edifice may be raised in heaven, that treasure may be laid up in that blessed land, caring naught for fame, profit or glory in this frail and uncertain life, but only for that other most certain and eternal life.

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.

Make then your forecasts, my lords Astrologers, with your slavish physicians, by means of those astrolabes with which you seek to discern the fantastic nine moving spheres; in these you finally imprison your own minds, so that you appear to me but as parrots in a cage, while I watch you dancing up and down, turning and hopping within those circles. We know that the Supreme Ruler cannot have a seat so narrow, so miserable a throne, so trivial, so scanty a court, so small and feeble a simulacrum that phantasm can bring to birth, a dream shatter, a delusion restore, a calamity diminish, a misdeed abolish and a thought renew it again, so that indeed with a puff of air it were brimful and with a single gulp it were emptied. On the contrary we recognize a noble image, a marvellous conception, a supreme figure, an exalted shadow, an infinite representation of the represented infinity, a spectacle worthy of the excellence and supremacy of Him who transcendeth understanding, comprehension or grasp. Thus is the excellence of God magnified and the greatness of his kingdom made manifest; He is glorified not in one, but in countless suns; not in a single earth, a single world, but in a thousand thousand, I say in an infinity of worlds.
