But comparison itself, when separated from the other kinds of discussion, will be considered according to its own intrinsic power, if that which is mentioned in the comparison is shown, either not to have been honourable, or not to have been useful, or not to have been necessary, or not so greatly useful, or not so very honourable, or not so exceedingly necessary.

In the next place it is desirable for the accuser to separate the action which he himself is accusing, from that which the advocate for the defence compares with it.  And he will do that if he shows that it is not usually done in such a manner, and that it ought not to be done so, and that there is no reason why this thing should be done on this account; for instance, that those things which have been provided for the sake of safety, should be surrendered to the enemy for the sake of safety.  Afterwards it will be desirable to compare the injury with the benefit, and altogether to compare the action which is impeached with that which is praised by the advocate for the defence or which is attempted to be proved as what must inevitably have ensued, and then, by disparaging the one at the same time to exaggerate the importance of the mischief caused by the other.  That will be effected if it be shown that that which the person on his trial avoided was more honourable, more advantageous, and more necessary than that which he did.  But the influence and character of what is honourable, and useful, and necessary, will be ascertained in the rules given for deliberation.

In the next place, it will be desirable to explain that comparative kind of judicial decision as if it were a deliberative cause and then afterwards to discuss it by the light thrown on it by rules for deliberation.  For let this be the question for judicial decision which we have already mentioned—­“As all the soldiers would have been lost if they had not come to this agreement, was it better for the soldiers to be lost, or to come to this agreement?” It will be desirable that this should be dealt with with reference to the topics concerning deliberation, as if the matter were to come to some consultation.

XXVI.  But the advocate for the defence will take the topics in accordance with which other statements of the case are made by the accuser, and will prepare his own defence from those topics with reference to the same statements.  But all other topics which belong to the comparison, he will deal with in the contrary manner.

The common topics will be these,—­the accuser will press his charges against the man who confesses some discreditable or pernicious action, or both, but still seeks to make some defence, and will allege the mischievous or discreditable nature of his conduct with great indignation.  The advocate for the defence will insist upon it, that no action ought to be considered pernicious or discreditable, or, on the other hand, advantageous or creditable, unless it is ascertained with what intention, at what time,
