>Trying to give up desire? Then what would motivate you do do anything at all?

This is a very poor reading of the Stoic philosophy, and a direct contradiction Epictetus' instructions (Long quote ahead, but it's essentially a direct response to this sort of criticism, so I think getting it all out at once is worthwhile):

>To the rational animal only is the irrational intolerable; but that which is rational is tolerable. Blows are not naturally intolerable. "How is that?" See how the Lacedaemonians endure whipping when they have learned that whipping is consistent with reason. "To hang yourself is not intolerable." When, then, you have the opinion that it is rational, you go and hang yourself. In short, if we observe, we shall find that the animal man is pained by nothing so much as by that which is irrational; and, on the contrary, attracted to nothing so much as to that which is rational.

>But the rational and the irrational appear such in a different way to different persons, just as the good and the bad, the profitable and the unprofitable. For this reason, particularly, we need discipline, in order to learn how to adapt the preconception of the rational and the irrational to the several things conformably to nature. But in order to determine the rational and the irrational, we use not only the of external things, but we consider also what is appropriate to each person. For to one man it is consistent with reason to hold a chamber pot for another, and to look to this only, that if he does not hold it, he will receive stripes, and he will not receive his food: but if he shall hold the pot, he will not suffer anything hard or disagreeable. But to another man not only does the holding of a chamber pot appear intolerable for himself, but intolerable also for him to allow another to do this office for him. If, then, you ask me whether you should hold the chamber pot or not, I shall say to you that the receiving of food is worth more than the not receiving of it, and the being scourged is a greater indignity than not being scourged; so that if you measure your interests by these things, go and hold the chamber pot. "But this," you say, "would not be worthy of me." Well, then, it is you who must introduce this consideration into the inquiry, not I; for it is you who know yourself, how much you are worth to yourself, and at what price you sell yourself; for men sell themselves at various prices.

>For this reason, when Florus was deliberating whether he should go down to Nero's spectacles and also perform in them himself, Agrippinus said to him, "Go down": and when Florus asked Agrippinus, "Why do not you go down?" Agrippinus replied, "Because I do not even deliberate about the matter." For he who has once brought himself to deliberate about such matters, and to calculate the value of external things, comes very near to those who have forgotten their own character. For why do you ask me the question, whether death is preferable or life? I say "life." "Pain or pleasure?" I say "pleasure." But if I do not take a part in the tragic acting, I shall have my head struck off. Go then and take a part, but I will not. "Why?" Because you consider yourself to be only one thread of those which are in the tunic. Well then it was fitting for you to take care how you should be like the rest of men, just as the thread has no design to be anything superior to the other threads. But I wish to be purple, that small part which is bright, and makes all the rest appear graceful and beautiful. Why then do you tell me to make myself like the many? and if I do, how shall I still be purple?

The Stoics do not say to desire nothing, only to desire those things which you can actually obtain, for as long as you can actually obtain them. Since Virtue is dependent only on one's own reasoning, and is therefore always available to everyone (Modern psychology has added some exceptions to this rule, but only of an exceptionally rare nature), it is the sole "Good" worth always pursuing, and other things which are sometimes within our reach and sometimes not are "Preferred Indifferents", which we choose to desire when we can have them (when we are willing to pay their price) and to not desire when we cannot, because it is in their nature to not be ours forever:

>With regard to whatever objects give you delight, are useful, or are deeply loved, remember to tell yourself of what general nature they are, beginning from the most insignificant things. If, for example, you are fond of a specific ceramic cup, remind yourself that it is only ceramic cups in general of which you are fond. Then, if it breaks, you will not be disturbed. If you kiss your child, or your wife, say that you only kiss things which are human, and thus you will not be disturbed if either of them dies.
