But they are free from pain.

Is that sufficient for beings who are supposed to enjoy all good things and the most supreme felicity?
The Deity, they say, is constantly meditating on his own happiness, for he has no other idea which can possibly occupy his mind.

Consider a little; reflect what a figure the Deity would make if he were to be idly thinking of nothing through all eternity but "It is very well with me, and I am happy;" nor do I see why this happy Deity should not fear being destroyed, since, without any intermission, he is driven and agitated by an everlasting incursion of atoms, and since images are constantly floating off from him.

Your Deity, therefore, is neither happy nor eternal.
Epicurus, it seems, has written books concerning sanctity and piety towards the Gods.

But how does he speak on these subjects?
You would say that you were listening to Coruncanius or Scaevola, the high-priests, and not to a man who tore up all religion by the roots, and who overthrew the temples and altars of the immortal Gods; not, indeed, with hands, like Xerxes, but with arguments; for what reason is there for your saying that men ought to worship the Gods, when the Gods not only do not regard men, but are entirely careless of everything, and absolutely do nothing at all?
But they are, you say, of so glorious and excellent a nature that a wise man is induced by their excellence to adore them.
