The task not merely of division, but of invention as well, is rendered materially easier by this method of examining all possible arguments and arriving at the best by a process of elimination. Milo is accused of killing Clodius. Either he did or did not do the deed. The best policy would be to deny the fact, but that is impossible. It is admitted then that he killed him. The act must then have been either right or wrong. We urge that it was right. If so, the act must have either been deliberate or under
The intention is doubtful, but as it is generally supposed to have existed, some attempt must he made to defend it and to show that it was for the good of the state. On the other hand, if we plead necessity, we shall argue that the fight was accidental and unpremeditated. One of the two parties then must have lain in wait for the other. Which was it? Clodius without doubt. Do you see how inevitably we are led to the right method of defence by the logical necessity of the facts?
We may carry the process further: either he wished to kill Clodius, who lay in wait for him, or he did not. The safer course is to argue that he did not wish to kill him. It was then the slaves of Milo who did the deed without Milo's orders or knowledge. But this line of defence shows a lack of courage and lessens the weight of our argument that Clodius was rightly killed.
We shall therefore add the words,
As every man would have wished his slaves to do under similar circumstances.[*](pro Mil. x. 29. V. iv. 8. ) This method is all the more useful from the fact that often we can find nothing to say that really pleases us and yet have got to say something. Let us therefore consider every possible point; for thus we shall discover what is the best line for us to pursue, or at any rate what is least bad. Sometimes, as I have already said in the appropriate context, [*](pro Mil. x. 29. V. iv. 8. ) we may make good use of the statement of our opponent, since occasionally it is equally to the purpose of both parties. I am aware that some authors have written thousands of lines to show how we may discover which party ought to speak first. But in the actual
