Cyropaedia

For, to have quitted yourselves once like valiant men does not, we know, assure the perpetuity of valour, unless you devote yourselves to it to the end; but, just as skill in other arts retrogrades if neglected, and as bodies, too, that were once in good condition change and deteriorate as soon as the owners relax into idleness, so also self-control and temperance and strength will take a backward turn to vice as soon as one ceases to cultivate them.

Therefore, we dare not become careless nor give ourselves up to the enjoyment of the present moment; for, while I think it is a great thing to have won an empire, it is a still greater thing to preserve it after it has been won. For to win falls often to the lot of one who has shown nothing but daring; but to win and hold—that is no longer a possibility without the exercise of self-control, temperance, and unflagging care.

Recognizing all this, we ought to practise[*](He emphasizes the Persians’ need) virtue even more than we did before we secured these advantages, for we may be sure that the more a man has, the more people will envy him and plot against him and become his enemies, particularly if, as in our case, he draws his wealth and service from unwilling hands. We must, therefore, believe that the gods will be on our side; for we have not come unjustly into our possessions through plotting against others, but plotted against we have avenged ourselves.

But that which is next in importance after the favour of the gods we must get for ourselves—namely, we must claim the right to rule over our subjects only on the ground that we are their betters. Now the conditions of heat and cold, food and drink, toil and rest, we must share even with our slaves. But though we share with them, we must above all try to show ourselves their betters in such matters;

but the science and practice of war we need not share at all with those whom we wish to put in the position of workmen or tributaries to us, but we must maintain our superiority in these accomplishments, as we recognize in these the means to liberty and happiness that the gods have given to men. And just as we have taken their arms away from them, so surely must we never be without our own, for we know that the nearer to their arms men constantly are, the more completely at their command is their every wish.

But if any one is revolving in his mind any[*](The secret of happiness) such questions as this—‘of what earthly use it is to us to have attained to the goal of our ambitions if we still have to endure hunger and thirst, toil and care’—he must take this lesson to heart: that good things bring the greater pleasure, in proportion to the toil one undergoes beforehand to attain them; for toil gives a relish to good things; and nothing, however sumptuously prepared, could give pleasure unless a man get it when he needs it.
