Cyropaedia (2.3.1-2.3.5)

Friends, the conflict is at hand; for the enemy are approaching. As for the prizes of victory, if we are victorious—and we must assume that we shall be and work to that end—it is evident that the enemy and all that is theirs will belong to us. But, on the other hand, if we are defeated—in this case, too, all the possessions of the vanquished are invariably the prizes set for the victors.

Accordingly,

you must realize that when men who are united as comrades in war are fully persuaded that nothing will come out as it should unless each individual man exerts himself, then many splendid achievements are speedily accomplished; for nothing that needs to be done is neglected. But when each one assumes that there will be some one else to do and to fight, even if he proves a weakling, let me assure you,

that to such men, all alike, all that is grievous comes in a flood.

And God has ordained it in some such way as this: in the case of those who will not compel themselves to work out their own good, he assigns others to be their commanders. Now, therefore, let any one[*] stand up and speak to this question before us, whether he thinks that valour would be more cultivated among us, if the one who will do and dare most is also to receive the greatest rewards, or if we know that it makes no difference whether a man be a coward or not, as we shall all share and share alike.

Well, Cyrus,

I think that you are introducing this discussion not because you think that the bad ought to have an equal share with the good, but because you wish to prove whether a single man will really be found who will care to let it be known that he thinks that, even if he himself does nothing good and noble, he should have an equal share of that which others win by their valour.
