Cyropaedia (2.3.6-2.3.10)

Now I,

am neither fleet of foot nor strong of arm, and I know that in view of what I shall accomplish by my bodily strength I should not be judged either the first or the second, or even, I suppose, the thousandth, and perhaps not even the ten thousandth. But on this point I am perfectly clear, that if those who are powerful men take matters vigorously in hand, I shall have as large a share of any good fortune that may come as I deserve. But if the bad do nothing and the good and strong lose heart, I am afraid,

that I shall have a larger share than I wish of something other than good.

I think, Cyrus,

and all you Persians here assembled, that we are all now starting on an equal footing in a contest of merit; for I observe that we are all taking the same bodily exercise, that we all have the same rations, that we are all considered worthy to move in the same society, and that the prizes are offered alike to all. For obedience to the officers has been enjoined equally upon us all, and whoever shows himself prompt to comply, I observe that he receives honour from Cyrus. Again, to be brave in the face of the enemy is not a thing to be expected of one and not of another, but it is considered far the noblest thing for all alike.

And now,

we have been initiated into a method of fighting, which, I observe, all men naturally understand, just as in the case of other creatures each understands some method of fighting which it has not learned from any other source than from instinct: for instance, the bull knows how to fight with his horns, the horse with his hoofs, the dog with his teeth, the boar with his tusks. And all know how to protect themselves, too, against that from which they most need protection, and that, too, though they have never gone to school to any teacher.

As for myself, I have understood from my very childhood how to protect the spot where I thought I was likely to receive a blow; and if I had nothing else I put out my hands to hinder as well as I could the one who was trying to hit me. And this I did not from having been taught to do so, but even though I was beaten for that very act of putting out my hands. Furthermore, even when I was a little fellow I used to seize a sword wherever I saw one, although, I declare, I had never learned, except from instinct, even how to take hold of a sword. At any rate, I used to do this, even though they tried to keep me from it—and certainly they did not teach me so to do—just as I was impelled by nature to do certain other things which my father and mother tried to keep me away from. And, by Zeus, I used to hack with a sword everything that I could without being caught at it. For this was not only instinctive, like walking and running, but I thought it was fun in addition to its being natural.
