De Natura Deorum - Cicero

Γιατί ο Επίκουρος κάνει καλό στην υγεία:

'We for our part deem happiness to consist in tranquillity of mind and entire exemption from all duties. For he who taught us all the rest has also taught us that the world was made by nature, without needing an artificer to construct it, and that the act of creation, which according to you cannot be performed without divine skill, is so easy, that nature will create, is creating, and has created worlds without number. You on the contrary cannot see how nature can achieve all this without the aid of some intelligence, and so, like the tragic poets, being unable to the plot of your drama to a dénouement, you have recourse to a god; whose intervention you assuredly would not require if you would but contemplate the measureless and boundless extent of space that stretches in every direction, into which when the mind projects and propels itself, it journeys onward far and wide without ever sighting any margin or ultimate point where it can stop. Well then, in this immensity of length and breadth and height there flits an infinite quantity of atoms innumerable, which though separated by void yet cohere together, and taking hold each of another form unions wherefrom are created those shapes and forms of things which you think cannot be created without the aid of bellows and anvils, and so have saddled us with an eternal master, whom day and night we are to fear; for who would not fear a prying busybody of a god, who foresees and thinks of and notices all things, and deems that everything is his concern?

“An outcome of this theology was first of all your doctrine of Necessity or Fate, heimarmene as you termed it, the theory that every event is the result of an eternal truth and an unbroken sequence of causation. But what value can be assigned to a philosophy which thinks that everything happens by fate? It is a belief for old women; and ignorant old women at that. And next follows your doctrine of mantike, or Divination, which would so steep us in superstition, if we consented to listen to you, that we should be the devotees of soothsayers, augurs, oracle-mongers, seers, and interpreters of dreams. But Epicurus has set us free from superstitious terrors and delivered us out of captivity, so that we have no fear of beings who, we know, create no trouble for themselves and seek to cause none to others, while we worship with reverence the transcendent majesty of nature.'
