Cosmos of the Ancients

Comsos of the Ancients

The Greek Philosophers on Myth and Cosmology


E picurus (341-270 BC) had two principal teachers - the Platonist Pamphilus in his teens, and Nausiphanes of Teos, who introduced him to the atomism of Democritus, in his twenties - but he distanced them firmly, calling the latter a "scoundrel", to form his own school of thought, which was extraordinary in allowing both sexes as students.

       The principal source to his life and theories is Diogenes Laertius, who wrote appreciatively and extensively about him in Lives of Eminent Philosophers. Epicurus is said to have written some 300 books, but what remains is principally some letters of his, and fragments mostly in the form of aphorisms. Among the letters, one known as the Lesser Epitome, written to his student Herodotus, later to break with and loudly criticize him, lays out the general lines of his cosmology as well as his ethics. Letters to some other students also remain, giving additional confirmations to the views of Epicurus.


       He stated that since nothing can be created from what does not exist, the universe must always have existed and always will be - consisting of bodies made up of atoms, in continual motion, and space. The universe must also be unlimited, since there cannot be a nothing outside of it, but within it "there is an infinite number of worlds, some like this world, others unlike it." These worlds are created out of the infinite and dissolved, some sooner and some later. Regarding the soul, Epicurus is quite precise:

       the soul is a corporeal thing, composed of fine particles, dispersed all over the frame, most nearly resembling wind with an admixture of heat, in some respects like wind, in others like heat. But again, there is the third part which exceeds the other two in the fineness of its particles and thereby keeps in closer touch with the rest of the frame.


       The body is unable to sense anything without the soul, as is the soul without the body. Therefore, when the soul leaves the body, no awareness remains. There cannot, according to Epicurus, be any afterlife. Death is a complete stop. This he regards as reason not to worry at all about dying: "death is nothing to us, for good and evil imply sentience, and death is the privation of all sentience." Life can only be enjoyable if one ceases to yearn for immortality, and renounces the fear of an endless afterlife in one or other torment: "either because of the myths, or because we are in dread of the mere insensibility of death, as if it had to do with us." When dying is simply ceasing to perceive, to feel, to be, there is nothing in it to dread.

       Death, therefore, the most awful of evils, is nothing to us, seeing that, when we are, death is not come, and, when death is come, we are not.

       Therefore, learning to live well is not different from learning to die well - the only reasonable way to prepare for the latter is to make the former, in itself and for itself, the fullest.

       It is in regards to celestial perspectives that Epicurus gives his views on the gods. The dynamics of the heavens, such as planetary movements, eclipses and so forth "take place without the ministration or command, either now or in the future, of any being who at the same time enjoys perfect bliss along with immortality." He has a slightly humorous way of robbing the gods of their powers by complimenting them, stating that such blissful creatures could not be dealing with troublesome worldly matters, or they would not be so blissful. They are above the world - thereby, it is implied but not outspoken by Epicurus, completely without role in, or relevance to, existence: "the divine nature must not on any account be adduced to explain this, but must be kept free from the task and in perfect bliss." It is as much saying that they do not exist at all, as is possible without actually saying it. So he dares to go on stating that misconceptions on this matter is a chief frustration to man:

       the greatest anxiety of the human mind arises through the belief that the heavenly bodies are blessed and indestructible, and that at the same time they have volitions and actions and causality inconsistent with this belief.


       What can be said about the cosmos, he stresses repeatedly, is only that which can be perceived about it. Therefore, in many cases, not much at all can be confirmed exclusively - there are several possibilities, more often than not, such as with the question of the size of the heavenly bodies:

       The size of the sun and the remaining stars relatively to us is just as great as it appears. But in itself and actually it may be a little larger or a little smaller, or precisely as great as it is seen to be.

       What he strongly objects to is stating one theory to be true and not the other, although there is no actual proof of it:

       But one must not be so much in love with the explanation by a single way as wrongly to reject all the others from ignorance of what can, and what cannot, be within human knowledge, and consequent longing to discover the indiscoverable.

       Certainly, both mythology and philosophy is blamed for this.
