Plato: The Republic

2. BOOK II (continued)

And if a poet writes of the sufferings of Niobe--the subject of the tragedy in which these iambic verses occur--or of the house of Pelops, or of the Trojan war or on any similar theme, either we must not permit him to say that these are the works of God, or if they are of God, he must devise some explanation of them such as we are seeking; he must say that God did what was just and right, and they were the better for being punished; but that those who are punished are miserable, and that God is the author of their misery-- the poet is not to be permitted to say; though he may say that the wicked are miserable because they require to be punished, and are benefited by receiving punishment from God; but that God being good is the author of evil to any one is to be strenuously denied, and not to be said or sung or heard in verse or prose by any one whether old or young in any well-ordered commonwealth. Such a fiction is suicidal, ruinous, impious.

I agree with you, he replied, and am ready to give my assent to the law.

Let this then be one of our rules and principles concerning the gods, to which our poets and reciters will be expected to conform-- that God is not the author of all things, but of good only.

That will do, he said.

And what do you think of a second principle? Shall I ask you whether God is a magician, and of a nature to appear insidiously now in one shape, and now in another--sometimes himself changing and passing into many forms, sometimes deceiving us with the semblance of such transformations; or is he one and the same immutably fixed in his own proper image?

I cannot answer you, he said, without more thought.

Well, I said; but if we suppose a change in anything, that change must be effected either by the thing itself, or by some other thing?

Most certainly.
