a resemblance of it. And it is owing to their not being able to discover the difference between them that some men ignorant of real excellence, and in what it consists, have been the destruction of their country and of themselves. And thus the best men have erred, not so much in their intentions as by a mistaken conduct. What? is no cure to be attempted to be applied to those who are carried away by the love of money, or the lust of pleasures, by which they are rendered little short of madmen, which is the case of all weak people? or is it because the disorders of the mind are less dangerous than those of the body? or because the body will admit of a cure, while there is no medicine whatever for the mind?
III. But there are more disorders of the mind than of the body, and they are of a more dangerous nature; for these very disorders are the more offensive because they belong to the mind and disturb it; and the mind, when disordered, is, as Ennius says, in a constant error: it can neither bear nor endure anything, and is under the perpetual influence of desires. Now, what disorders can be worse to the body than these two distempers of the mind (for I overlook others), weakness and desire? But how, indeed, can it be maintained that the mind cannot prescribe for itself, when she it is who has invented the medicines for the body, when, with regard to bodily cures, constitution and nature have a great share, nor do all who suffer themselves to be cured find that effect instantly; but those minds which are disposed to be cured, and submit to the precepts of the wise, may undoubtedly recover a healthy state? Philosophy is certainly the medicine of the soul, whose assistance we do not seek from abroad, as in bodily disorders, but we ourselves are bound to exert our utmost energy and power in order to effect our cure. But as to philosophy in general, I have, I think, in my Hortensius, sufficiently spoken of the credit and attention which it deserves: since that, indeed, I have been continually either disputing or writing on its most material branches; and I have laid down in these books all the discussions which took place between myself and my particular friends at my Tusculan villa. But as I have spoken in the two former of pain and death, this book shall be
