*1* I. I believe, Marcus, my son, that I have fully explained in the preceding book how duties are from moral rectitude, or rather from each of virtue's four divisions. My next step is to trace out those kinds of duty which have to do with the comforts of life, with the means of acquiring the things that people enjoy, with influence, and with wealth. [In this connection, the question is, as I said: (1) what is expedient, and what is inexpedient; and (2) of several expedients, which is of more and which of most importance.] These questions I shall proceed to discuss, after I have said a few words in vindication of my present purpose and my principles of philosophy. #Why Cicero wrote on philosophy.# *2* Although my books have aroused in not a few men the desire not only to read but to write, yet I sometimes fear that what we term philosophy is distasteful to certain worthy gentlemen, and that they wonder that I devote so much time and attention to it. Now, as long as the state was administered by the men to whose care she had voluntarily entrusted herself, I devoted all my effort and thought to her. But when everything passed under the absolute control of a despot and there was no longer any room for statesmanship or authority of mine; and finally when I had lost the friends[AH] who had been associated with me in the task of serving the interests of the state, and who were men of the highest standing, I did not resign myself to grief, by which I should have been overwhelmed, had I not struggled against it; neither, on the other hand, did I surrender myself to a life of sensual pleasure unbecoming to a philosopher. *3* I would that the government had stood fast in the position it had begun to assume and had not fallen into the hands of men who desired not so much to reform as to abolish the constitution. For then, in the first place, I should now be devoting my energies more to public speaking than to writing, as I used to do when the republic stood; and in the second place, I should be committing to written form not these present essays but my public speeches, as I often formerly did. But when the republic, to which all my care and thought and effort used to be devoted, was no more, then, of course, my voice was silenced in the forum and in the senate. *4* And since my mind could not be wholly idle, I thought, as I had been well-read along these lines of thought from my early youth, that the most honourable way for me to forget my sorrows would be by turning to philosophy. As a young man, I had devoted a great deal of time to philosophy as a discipline; but after I began to fill the high offices of state and devoted myself heart and soul to the public service, there was only so much time for philosophical studies as was left over from the claims of my friends and of the state; all of this was spent in reading; I had no leisure for writing.
