XLVII.  But any one who speaks against the letter of the law will first of all introduce that topic by which the equity of the excuse is proved; or he will point out with what feelings, with what design, and on what account he did the action in question.  And whatever excuse he alleges he will defend according to some of the rules which I have already given with respect to assumptions.  And when he has dwelt on this topic for some time, and set forth the principles of his conduct and the equity of his cause in the most specious manner he can, he will also add, in opposition to the arguments of his adversaries, that it is from these topics for the most part that excuses which are admissible ought to be drawn.  He will urge that there is no law which sanctions the doing of any disadvantageous or unjust action; that all punishments which are enacted by the laws have been enacted for the sake of chastising guilt and wickedness; that the very framer of the laws, if he were alive, would approve of this conduct, and would have done the very same thing himself if he had been in similar circumstances.  And that it is on this account that the framer of the law appointed judges of a certain rank and age, in order that there might be men, not capable merely of reading out what he had written, which any boy might do, but able also to understand his thoughts and to interpret his intentions.  He will add, that that framer of the law, if he had been intrusting the laws which he was drawing up to foolish men and illiterate judges, would have set down everything with the most scrupulous diligence; but, as it is, because he was aware what sort of men were to be the judges, he did not put down many things which appeared to him to be evident; and he expected that you would be not mere readers of his writings, but interpreters of his intentions.  Afterwards he will proceed to ask his adversaries—­“What would you say if I had done so and so?” “What would you think if so and so had happened?” “Suppose any one of those things had happened which would have had a most unfailing excuse, or a most undeniable necessity, would you then have prosecuted me?” But the law has nowhere made any such exception.  It follows, therefore, that it is not every possible circumstance which is mentioned in the written law but that some things which are self-evident are guarded against by unexpressed exceptions.  Then he will urge, that nothing could be carried on properly either by the laws or by any written document whatever, or even in daily conversation, or in the commands given in a private household, if every one chose to keep his eyes on the exact language of the order, and not to take into consideration the intentions of him who uttered the order.
