The Eighth doth demonstrate that the motion of the infinity of worlds [8] is not the result of external motive force, but of their own nature, and that despite this there existeth an infinite motor force.
The Ninth sheweth how infinite motion may be intensively verified in each of the worlds. To this we should add that since each moving body at the same time moveth itself and is moved, needs must that it may be seen in every point of the circle that it describeth around its own centre. And this objection we discharge on other occasions when it will be permissible to present the more diffuse doctrine.
Italian Dominican friar, philosopher and mathematician (1548–1600)
Giordano Bruno (1548 – 17 February 1600) was an Italian universalist pantheist monist philosopher, mathematician, astronomer and poet, who, following an Inquisition for heresy and the denial of several Catholic doctrines, was burned at the stake in Rome, 1600; born Filippo Bruno, in Nola, Italy, he often called himself Il Nolano (The Nolan).

Thou seest therefore that by this reasoning Aristotle doth attribute to God extensive infinity but not absolute intensive infinity withal, whence I would conclude that as his infinite motive power is constrained to motive action in conformity with finite speed, so also the same power of creating the immense and the innumerable is limited by his own will to the finite and numerable. Some theologians have argued almost in the same way, since besides admitting infinity in extension, whereby God conveyeth perpetual motion to the universe, they require also intensive infinity with which he can create and move innumerable worlds, and cause each of them and all at once to move instantaneously; nevertheless God hath thus limited by his will the number of the innumerable multitude of worlds, and also the quality of utterly intensive motion. And as this motion, which proceedeth indeed from infinite power (nothing interfering), is recognized as finite, so also the number of worlds may easily be believed to be determinate.

It is then unnecessary to investigate whether there be beyond the heaven Space, Void or Time. For there is a single general space, a single vast immensity which we may freely call Void; in it are innumerable globes like this one on which we live and grow. This space we declare to be infinite, since neither reason, convenience, possibility, sense-perception nor nature assign to it a limit. In it are an infinity of worlds of the same kind as our own.
Everything that makes diversity of kinds, of species, differences, properties... everything that consists in generation, decay, alteration and change is not an entity, but a condition and circumstance of entity and being, which is one, infinite, immobile, subject, matter, life, death, truth, lies, good and evil.
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.
Thirdly, it will be propounded that every star hath motion even as hath our own and those others which are so near to us that we can sensibly perceive the differences in their orbits and in their motions: but those suns, bodies in which fire doth predominate, move differently to the earths in which water predominateth; thus may be understood whence is derived the light diffused by stars, of which some glow of themselves and others by reflection.
When the end comes, you will be esteemed by the world and rewarded by God, not because you have won the love and respect of the princes of the earth, however powerful, but rather for having loved, defended and cherished one such as I ... what you receive from others is a testimony to their virtue; but all that you do for others is the sign and clear indication of your own.
Twelfthly, there is no reason or sense-perception which, since we accept an infinity undivided, utterly simple and all-embracing, will not permit also a corporeal and extended infinity.
Thirteenthly, our own surrounding space which appeareth to us so immense is neither part nor whole in relation to the infinite; nor can it be patient of infinite activity; compared to such activity, indeed, that which can be comprehended by our imbecile minds is merely nonbeing. And to a certain objection it may be replied that we base our argument for infinity not on the dignity of space but on the dignity of the natures [of worlds], since for the same reason that our space doth exist, so also should exist every other possible world; and their power of being is not actuated by our world's being, just as Elpino's power of being is not actuated by the existence of Fracastoro.
Unless you make yourself equal to God, you cannot understand God: for the like is not intelligible save to the like. Make yourself grow to a greatness beyond measure, by a bound free yourself from the body; raise yourself above all time, become Eternity; then you will understand God. Believe that nothing is impossible for you, think yourself immortal and capable of understanding all, all arts, all sciences, the nature of every living being. Mount higher than the highest height; descend lower than the lowest depth. Draw into yourself all sensations of everything created, fire and water, dry and moist, imagining that you are everywhere, on earth, in the sea, in the sky, that you are not yet born, in the maternal womb, adolescent, old, dead, beyond death. If you embrace in your thought all things at once, times, places, substances, qualities, quantities, you may understand God.
We are wont to say that it was not in our power to choose the parents who fell to our lot, that they have been given to men by chance; yet we may be the sons of whomsoever we will. Households there are of noblest intellects; choose the one into which you wish to be adopted; you will inherit not merely their name, but even their property, which there will be no need to guard in a mean or niggardly spirit; the more persons you share it with, the greater it will become. These will open to you the path to immortality, and will raise you to a height from which no one is cast down. This is the only way of prolonging mortality — nay, of turning it into immortality. Honours, monuments, all that ambition has commanded by decrees or reared in works of stone, quickly sink to ruin; there is nothing that the lapse of time does not tear down and remove. But the works which philosophy has consecrated cannot be harmed; no age will destroy them, no age reduce them; the following and each succeeding age will but increase the reverence for them, since envy works upon what is close at hand, and things that are far off we are more free to admire. The life of the philosopher, therefore, has wide range, and he is not confined by the same bounds that shut others in. He alone is freed from the limitations of the human race; all ages serve him as if a god. Has some time passed by? This he embraces by recollection. Is time present? This he uses. Is it still to come? This he anticipates. He makes his life long by combining all times into one.
Philotheo: All of this is true, and contradicts nothing we've said, rather to the contrary we've said that there are dissimilar finite parts in one infinity, and have offered considerations how this might be true. Perhaps it might be expressed proportionately, how one might have many continuous parts which form a unity, using the example and simile of liquid mud, which, though water is contiguous with water in every part, and earth with earth, smaller than we can apprehend sensibly, these are called neither discrete nor continuous, not water nor earth, but only a continuum of mud; another might like to say that since the atoms of water are not actually continuous with one another, nor earth with earth, but perhaps water with earth and earth with water; a third might disagree with both and say only mud is continuous with mud. Following these reasons it can be stated that the infinite universe is a continuum, in which discreteness is not created by the interposition of ether between the great celestial bodies, than it would be were air to be mixed and interposed among the dry and watery particles, the difference being only in the consistency of the smallest parts of the mud, beneath the level of our sensible apprehension, or in the size, greatness, and sensibility of the parts that make up our universe: and so, contrary and diverse moving parts cooperate and compose a single immobile continuum, where contraries converge to make up a single whole, achieve single order, and become one. Certainly, it would be inconvenient and impossible to imagine two infinities distinct from one another, since it would be impossible to imagine the dividing line between them, where one infinity would end and the other begin, or in what way each would terminate against the other. Moreover, it is extremely difficult to imagine two bodies which are finite and bounded on one side and infinite on the other.
