For I know how well ordered and equable your mind is, and am fully aware that it was not a surname alone which you brought home with you from Athens, but its culture and good sense. And yet I have an idea that you are at times stirred to the heart by the same circumstances as myself. To console you for these is a more serious matter, and must be put off to another time. For the present I have resolved to dedicate to you an essay on Old Age. For from the burden of impending or at least advancing age, common to us both, I would do something to relieve us both though as to yourself I am fully aware that you support and will support it, as you do everything else, with calmness and philosophy. But directly I resolved to write on old age, you at once occurred to me as deserving a gift of which both of us might take advantage. To myself, indeed, the composition of this book has been so delightful, that it has not only wiped away all the disagreeables of old age, but has even made it luxurious and delightful too. Never, therefore, can philosophy be praised as highly as it deserves considering that its faithful disciple is able to spend every period of his life with unruffled feelings. However, on other subjects I have spoken at large, and shall often speak again: this book which I herewith send you is on Old Age. I have put the whole discourse not, as Alisto of Cos did, in the mouth of Tithonus--for a mere fable would have lacked conviction--but in that of Marcus Cato when he was an old man, to give my essay greater weight. I represent Laelius and Scipio at his house expressing surprise at his carrying his years so lightly, and Cato answering them. If he shall seem to shew somewhat more learning in this discourse than he generally did in his own books, put it down to the Greek literature of which it is known that he became an eager student in his old age. But what need of more? Cato's own words will at once explain all I feel about old age. M. Cato. Publius Cornelius Scipio Africanus (the younger). Gaius Laelius. 2. _Scipio_. Many a time have I in conversation with my friend Gaius Laelius here expressed my admiration, Marcus Cato, of the eminent, nay perfect, wisdom displayed by you indeed at all points, but above everything because I have noticed that old age never seemed a burden to you, while to most old men it is so hateful that they declare themselves under a weight heavier than Aetna.
