M. Tullius Cicero, De Officiis
Walter Miller, Ed.

[39] And yet on this point certain philosophers, who are not at all vicious but who are not very discerning, declare that the story related by Plato is fictitious and imaginary. As if he affirmed that it was actually true or even possible! But the force of the¹ illustration of the ring is this: if nobody were to know or even to suspect the truth, when you do anything to gain riches or power or sovereignty or sensual gratification—if your act should be hidden for ever from the knowledge of gods and men, would you do it? The condition, they say, is impossible. Of course it is. But my question is, if that were possible which they declare to be impossible, what, pray, would one do? They press their point with right boorish obstinacy: they assert that it is impossible and insist upon it; they refuse to see the meaning of my words, “if possible.” For when we ask what they would do, if they could escape detection, we are not asking whether they can escape detection; but we put them as it were upon the rack: should they answer that, if impunity were assured, they would do what was most to their selfish interest, [p. 309] that would be a confession that they are criminally minded; should they say that they would not do so, they would be granting that all things in and of themselves immoral should be avoided.

But let us now return to our theme.
