And, if there is need to speak in brief summary of this power, we shall find that none of the things which are done with intelligence take place without the help of speech, but that in all our actions as well as in all our thoughts speech is our guide, and is most employed by those who have the most wisdom. Therefore, those who dare to speak with disrespect of educators and teachers of philosophy deserve our opprobrium no less than those who profane the sanctuaries of the gods.

I, myself, welcome all forms of discourse which are capable of benefiting us even in a small degree; however, I regard those as the best and most worthy of a king, and most appropriate to me, which give directions on good morals and good government;The aim of the worthy orator is proper conduct in private and in public life. See Isoc. 4.4, and General Introduction, pp. xxiv ff. and especially those which teach how men in power should deal with the people, and how the rank and file should be disposed to their rulers. For I observe that it is through such discourses that states attain the highest prosperity and greatness.

On the former topic, how a ruler should act, you have heard Isocrates speak; on the following topic, what his subjects must do, I shall attempt to discourse, not with any thought of excelling him, but because this is the most fitting subject for me to discuss with you. For if I did not make clear what I desire you to do, I could not reasonably be angry with you if you were to mistake my purpose; but if, after I have announced my policy beforehand, none of my desires are carried out, then I should justly blame those who fail to obey me.

And I believe that I should most effectively exhort you and urge you to remember my words and heed them, not if I should confine myself to giving you advice and then, after counting out my precepts, make an end, but if, before doing this, I should prove to you, first, that you ought to be content with our present government, not only from necessity, nor because we have lived under it all our lives, but because it is the best of all governments;
