Bearing these examples in mind, you should not honor that courage which accompanies heedless folly and unseasonable ambition, nor, when so many hazards which are inherent in monarchy are at hand, should you devise for yourself still others that bring no glory and belong to the common soldier; nor should you vie with those who wish to escape from an unhappy existence or who rashly incur danger in the hope of a higher wage;

nor should you desire such glory as many, both Greeks and barbarians, obtain, but rather that exalted renown which you alone of living men could win. Nor should you be enamored of such virtues as even ignoble men share, but only of those of which no base person may partake;

nor wage inglorious and difficult wars when honorable and easy ones are possible, nor those which will cause grief and anxiety to your closest friends and arouse great hope in your enemies, as even now you have done. Nay, as to the barbarians with whom you are now waging war, it will suffice you to gain the mastery over them only so far as to secure the safety of your own territory, but the king who is now called Great you will attempt to overthrow, that you may both enhance your own renown and may point out to the Greek world who the enemy is against whom they should wage war.The Persians are, of course, meant.

I should have greatly preferred to send you this letter before your campaign in order that, had you heeded my advice, you might not have incurred so great danger, or if you had rejected it, I should not now seem to be advising that same caution which has already, because of the wound you received, been approved by all; but, instead, your misfortune would be bearing witness to the truth of what I had said about the matter.
