Again, we know that men who are less generously endowed by nature but excel in experience and practice, not only improve upon themselves, but surpass others who, though highly gifted, have been too negligent of their talents. It follows, therefore, that either one of these factors may produce an able speaker or an able man of affairs, but both of them combined in the same person might produce a man incomparable among his fellows. These, then, are my views as to the relative importance of native ability and practice. I cannot, however, make a like claim for education; its powers are not equal nor comparable to theirs. For if one should take lessons in all the principles of oratory and master them with the greatest thoroughness, he might, perhaps, become a more pleasing speaker than most, but let him stand up before the crowd and lack one thing only, namely, assurance, and he would not be able to utter a word. But let no one of you think that before you I belittle my pretensions, while when I address those who desire to become my pupils I claim every power for my teaching; for it was to avoid just such a charge as this that, when I entered upon my profession, I wrote and published a discourse in which you will find that I attack those who make pretensions which are unwarranted, and set forth my own ideas. Now I am not going to quote from it my criticisms of others; for they are too long for the present occasion; but I shall attempt to repeat to you that part in which I express my own views. I begin at this point. Isoc. 13.14-18 Now this quotation is of a more finished style The earlier compositions are more finished as to rhythm and musical quality. See Isoc. 5.27 . than what has been said before, but its meaning is the same, and this ought to be taken by you as a convincing proof of my honesty; for you see that I did not brag and make big promises when I was young only to speak modestly for my philosophy now that I have reaped the harvest of my labors and am an old man, but that, on the contrary, I speak in the same terms both when I was at the height of my career and now when I am ready to retire from it, both when I had no thought of danger and now when I stand in jeopardy, and both in addressing those who wanted to become my pupils and now in addressing those who are to vote upon my fate. I do not see, therefore, how the sincerity and honesty of my professions could be more clearly shown.
