And since philosophy falls into three divisions, physics, ethics and dialectic, which, I ask you, of these departments is not closely connected with the task of the orator? Let us reverse the order just given and deal first with the third department which is entirely concerned with words. If it be true that to know the properties of each word, to clear away ambiguities, to unravel perplexities, to distinguish between truth and falsehood, to prove or to refute as may be desired, all form part of the functions of an orator, who is there that can doubt the truth of my contention?

I grant that we shall not have to employ dialectic with such minute attention to detail when we are pleading in the courts as when we are engaged in philosophical debate, since the orator's duty is not merely to instruct, but also to move and delight his audience; and to succeed in doing this he needs a strength, impetuosity and grace as well. For oratory is like a river: the current is stronger when it flows within deep banks and with a mighty flood, than when the waters are shallow and broken by the pebbles that bar their way.

And just as the trainers of the wrestling school do not impart the various throws to their pupils that those who have learnt them may make use of all of them in actual wrestling matches (for weight and strength and wind count for more than these), but that they may have a store from which to draw one or two of such tricks, as occasion may offer;

even so the science of dialectic, or if you prefer it of disputation, while it is often useful in definition, inference, differentiation, resolution of ambiguity, distinction and classification, as also in luring on or entangling our opponents, yet if it claim to assume the entire direction of the struggles of the forum, will merely stand in the way of arts superior to itself and by its very subtlety will exhaust the strength that has been pared down to suit its limitations.

As a result you will find that certain persons who show astonishing skill in philosophical debate, as soon as they quit the sphere of their quibbles, are as helpless in any case that demands more serious pleading as those small animals which, though nimble enough in a confined space, are easily captured in an open field.

Proceeding to moral philosophy or ethics, we may note that it at any rate is entirely suited to the orator. For vast as is the variety of cases (since in them, as I have pointed out in previous books, we seek to discover certain points by conjecture, See vi. 45. reach our conclusions in others by means of definition, See III. vi. 45. dispose of others on legal grounds' or by raising the question of competence, See ill. vi. 23. while other points are established by syllogism See III. vi. 15. and others involve contradictions Probably an allusion to contradictory laws. See VIII. vii. or are diversely interpreted owing to some ambiguity of language See VII. ix. ), there is scarcely a single one which does not at some point or another involve the discussion of equity and virtue, while there are also, as everyone knows, not a few which turn entirely on questions of quality.

Again in deliberative assemblies how can we advise a policy without raising the question of what is honourable? Nay, even the third department of oratory, which is concerned with the tasks of praise and denunciation, must without a doubt deal with questions of right and wrong.

For the orator will assuredly have much to say on such topics as justice, fortitude, abstinence, self-control and piety. But the good man, who has come to the knowledge of these things not by mere hearsay, as though they were just words and names for his tongue to employ, but has grasped the meaning of virtue and acquired a true feeling for it, will never be perplexed when he has to think out a problem, but will speak out truly what he knows.

Since, however, general questions are always more important than special (for the particular is contained in the universal, while the universal is never to be regarded as something superimposed on the particular), everyone will readily admit that the studies of which we are speaking are pre-eminently concerned with general questions.

Further, since there are numerous points which require to be determined by appropriate and concise definitions (hence the definitive basis See III vi. 31. of cases), it is surely desirable that the orator should be instructed in such things by those who have devoted special attention to the subject. Again, does not every question of law turn either on the precise meaning of words, the discussion of equity, or conjecture as to the intention—subjects which in part encroach on the domain of dialectic and in part on that of ethics?

Consequently all oratory involves a natural admixture of all these philosophic elements—at least, that is to say, all oratory that is worthy of the name. For mere garrulity that is ignorant of all such learning must needs go astray, since its guides are either non-existent or false. Physics i.e. natural phlilosophy in the widest sense. on the other hand is far richer than the other branches of philosophy, if viewed from the standpoint of providing exercise in speaking, in proportion as a loftier inspiration is required to speak of things divine than of things human; and further it includes within its scope the whole of ethics, which as we have shown § 15. are essential to the very existence of oratory.
