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.

And things which are at their best are also least liable to be altered
or discomposed; for example, when healthiest and strongest, the human
frame is least liable to be affected by meats and drinks, and the plant
which is in the fullest vigour also suffers least from winds or the heat
of the sun or any similar causes.

Of course.

And will not the bravest and wisest soul be least confused or deranged
by any external influence?

True.

And the same principle, as I should suppose, applies to all composite
things--furniture, houses, garments: when good and well made, they are
least altered by time and circumstances.

Very true.

Then everything which is good, whether made by art or nature, or both,
is least liable to suffer change from without?

True.

But surely God and the things of God are in every way perfect?

Of course they are.

Then he can hardly be compelled by external influence to take many
shapes?

He cannot.

But may he not change and transform himself?

Clearly, he said, that must be the case if he is changed at all.

And will he then change himself for the better and fairer, or for the
worse and more unsightly?

If he change at all he can only change for the worse, for we cannot
suppose him to be deficie
