Context: This most beautiful System of the Sun, Planets and Comets, could only proceed from the counsel and dominion of an intelligent and powerful being. And if the fixed Stars are the centers of other like systems, these being form'd by the like wise counsel, must be all subject to the dominion of One; especially, since the light of the fixed Stars is of the same nature with the light of the Sun, and from every system light passes into all the other systems. And lest the systems of the fixed Stars should, by their gravity, fall on each other mutually, he hath placed those Systems at immense distances one from another.

On the Sizes and Distances of the Sun and the Moon (c. 250 BC)

“Those who are most moral are farthest from the problem.”

“If, then, the things achieved by nature are more excellent than those achieved by art, and if art produces nothing without making use of intelligence, nature also ought not to be considered destitute of intelligence. If at the sight of a statue or painted picture you know that art has been employed, and from the distant view of the course of a ship feel sure that it is made to move by art and intelligence, and if you understand on looking at a horologe, whether one marked out with lines, or working by means of water, that the hours are indicated by art and not by chance, with what possible consistency can you suppose that the universe which contains these same products of art, and their constructors, and all things, is destitute of forethought and intelligence? Why, if any one were to carry into Scythia or Britain the globe which our friend Posidonius has lately constructed, each one of the revolutions of which brings about the same movement in the sun and moon and five wandering stars as is brought about each day and night in the heavens, no one in those barbarous countries would doubt that that globe was the work of intelligence.”
Si igitur meliora sunt ea quae natura quam illa quae arte perfecta sunt, nec ars efficit quicquam sine ratione, ne natura quidem rationis expers est habenda. Qui igitur convenit, signum aut tabulam pictam cum aspexeris, scire adhibitam esse artem, cumque procul cursum navigii videris, non dubitare, quin id ratione atque arte moveatur, aut cum solarium vel descriptum vel ex aqua contemplere, intellegere declarari horas arte, non casu, mundum autem, qui et has ipsas artes et earum artifices et cuncta conplectatur consilii et rationis esse expertem putare. [88] Quod si in Scythiam aut in Brittanniam sphaeram aliquis tulerit hanc, quam nuper familiaris noster effecit Posidonius, cuius singulae conversiones idem efficiunt in sole et in luna et in quinque stellis errantibus, quod efficitur in caelo singulis diebus et noctibus, quis in illa barbaria dubitet, quin ea sphaera sit perfecta ratione.

De Natura Deorum – On the Nature of the Gods (45 BC)
As quoted in The Discovery of Nature (1965), by Albert W. Bettex
Context: There are countless suns and countless earths all rotating round their suns in exactly the same way as the seven planets of our system. We see only the suns because they are the largest bodies and are luminous, but their planets remain invisible to us because they are smaller and non-luminous. The countless worlds in the universe are no worse and no less inhabited than our earth. For it is utterly unreasonable to suppose that those teeming worlds which are as magnificent as our own, perhaps more so, and which enjoy the fructifying rays of a sun just as we do, should be uninhabited and should not bear similar or even more perfect inhabitants than our earth. The unnumbered worlds in the universe are all similar in form and rank and subject to the same forces and the same laws. Impart to us the knowledge of the universality of terrestrial laws throughout all worlds and of the similarity of all substances in the cosmos! Destroy the theories that the earth is the center of the universe! Crush the supernatural powers said to animate the world, along with the so-called crystalline spheres! Open the door through which we can look out into the limitless, unified firmament composed of similar elements and show us that the other worlds float in an ethereal ocean like our own! Make it plain to us that the motions of all the worlds proceed from inner forces and teach us in the light of such attitudes to go forward with surer tread in the investigation and discovery of nature! Take comfort, the time will come when all men will see as I do.
