Behold, however, others, not philosophers indeed, but men of ready power in disputation, who affirm that all men are happy who live according to their own will. But this is certainly untrue, for to wish that which is unbecoming is itself a most miserable thing; nor is it so miserable a thing to fail in obtaining what you wish as to wish to obtain what you ought not to desire.
Another quotation Augustine gives us from Cicero's Hortensius, this time from a letter to Proba. Augustine's comment on it:
What is your opinion? Are not these words, by whomsoever they are spoken, derived from the Truth itself? We may therefore here say what the apostle said of a certain Cretan poet whose sentiment had pleased him: “This witness is true.”
And, indeed, Augustine seems to have been very pleaed with this passage; he quotes it in the De Trinitate (XIII.8) as well with equal insistence on its truth. His comment there is also worth reproducing:
But when Cicero, too, had propounded this in opposition to himself, he so refuted it as to make them blush who thought so. For he says: "But, behold! people who are not indeed philosophers, but who yet are prompt to dispute, say that all are blessed, whoever live as they will;" which is what we mean by, as pleases each. But by and by he has subjoined: "But this is indeed false. For to will what is not fitting, is itself most miserable; neither is it so miserable not to obtain what one wills, as to will to obtain what one ought not." Most excellently and altogether most truly does he speak. For who can be so blind in his mind, so alienated from all light of decency, and wrapped up in the darkness of indecency, as to call him blessed, because he lives as he will, who lives wickedly and disgracefully; and with no one restraining him, no one punishing, and no one daring even to blame him, nay more, too, with most people praising him, since, as divine Scripture says, "The wicked is praised in his heart's desire: and he who works iniquity is blessed," gratifies all his most criminal and flagitious desires; when, doubtless, although even so he would be wretched, yet he would be less wretched, if he could have had nothing of those things which he had wrongly willed? For every one is made wretched by a wicked will also, even though it stop short with will but more wretched by the power by which the longing of a wicked will is fulfilled. And, therefore, since it is true that all men will to be blessed, and that they seek for this one thing with the most ardent love, and on account of this seek everything which they do seek; nor can any one love that of which he does not know at all what or of what sort it is, nor can be ignorant what that is which he knows that he wills; it follows that all know a blessed life. But all that are blessed have what they will, although not all who have what they will are forewith blessed. But they are forewith wretched, who either have not what they will, or have that which they do not rightly will. Therefore he only is a blessed man, who both has all things which he wills, and wills nothing ill.
