Cicero on Intelligent Design

Read at Archive.org

Stoicism was a philosophy that was founded in Athens in 300 BC and became popular in the Roman Empire among such leaders as Seneca and Marcus Aurelius. In these selections from Cicero’s On the Nature of the Gods (45 BC), Cicero outlines the basic Stoic argument about design in nature. The selections come from Book II, chapters XXXVII, XLIV, and XLVII.

Who would not deny the name of human being to a man who, on seeing the regular motions of the heaven and the fixed order of the stars and the accurate interconnexion and interrelation of all things, can deny that these things possess any rational design, and can maintain that phenomena, the wisdom of whose ordering transcends the capacity of our wisdom to understand it, take place by chance? When we see something moved by machinery, like an orrery or clock or many other such things, we do not doubt that these contrivances are the work of reason; when therefore we behold the whole compass of the heaven moving with revolutions of marvelous velocity and executing with perfect regularity the annual changes of the seasons with absolute safety and security for all things, how can we doubt that all this is effected not merely by reason, but by a reason that is transcendent and divine?…

Can any sane person believe that all this array of stars and this vast celestial adornment could have been created out of atoms rushing to and fro fortuitously and at random? or could any other being devoid of intelligence and reason have created them? Not merely did their creation postulate intelligence, but it is impossible to understand their nature without intelligence of a high order…

To come now from things celestial to things terrestrial, which is there among these latter which does not clearly display the rational design of an intelligent being? In the first place, with the vegetation that springs from the earth, the stocks both give stability to the parts which they sustain and draw from the ground the sap to nourish the parts upheld by the roots; and the trunks are covered with bark or rind, the better to protect them against cold and heat. Again the vines cling to their props with their tendrils as with hands, and thus raise themselves erect like animals. Nay more, it is said that if planted near cabbages they shun them like pestilential and noxious things, and will not touch them at any point. Again what a variety there is of animals, and what capacity they possess of persisting true to their various kinds! Some of them are protected by hides, others are clothed with fleeces, others bristle with spines; some we see covered with feathers, some with scales, some armed with horns, some equipped with wings to escape their foes. Nature, however, has provided with bounteous plenty for each species of animal that food which is suited for it. I might show in detail what provision has been made in the forms of the animals for appropriating and assimilating this food, how skilful and exact is the disposition of the various parts, how marvelous the structure of the limbs. For all the organs, at least those contained within the body, are so formed and so placed that none of them is superfluous or not necessary for the preservation of life.
