'The necessity for a Preface often arises from some contrariety in an Author's position which prevents him from writing as he would wish to write. It is admitted that it is not fair to expect the same degree of excellence from a busy man which we may reasonably look for in a man of leisure. But a man in high official position cannot be a man of leisure. It would be the highest disgrace to him if he were, since even his so-called privy-chamber[708] resounds with the noise of clamorous litigants.

'I can well understand that a man of few occupations will object against me, here that a word has been thrown out with ill-considered haste, there that a commonplace sentiment has not been dressed up in sufficiently ornamental language, or there that I have not complied with the rules of the Ancients by making my persons speak "in character." But the busy man, hurried from one cause to another, and constantly under the necessity of dictating to one man and replying to another, will not make these objections, because the consciousness of his own literary perils will make him tender in his judgments. And yet there is something even in the pressure of business which sometimes promotes briskness of mind, since the art of speaking is one which is placed very much in our own power[709].

'If anyone objects that I, placed in the height of the Praetorian dignity, should have dictated so few decisions of a legal kind, let him know that this was the result of my associating with myself that most prudent man Felix[710], whose advice I have followed in every case. He is a man of absolute purity of character, of surpassing knowledge of the law, of distinguished accuracy of speech; a young man with the gravity of age, a sweet pleader, a measured orator; one who by his graceful discharge of his official duties has earned the favourable opinion of the public.

'Had it not been for his help, overwhelmed by so great a multitude of causes, I must either have been found unequal to the burden, or else perchance have seemed arrogant [in my disregard of previously settled decisions]. But, what was more important still, relieved by his labours from this duty, I was able to give such attention to the higher affairs of the State, that I could not fail to win approbation even in those arduous duties.

'I have therefore subjoined two books, in which I myself speak in my capacity as Praefect, to the ten in which I have spoken by the mouth of the King; for it seemed absurd to me to be silent in my newly-acquired dignity, who had so often spoken on behalf of others.

'Then, after these twelve books had been brought to their long-desired end, my friends compelled me to discuss the substance and the powers of the Soul, that I might say something about that faculty through which I had already said so much[711].

'Now then, learned men! view these letters with indulgence. If there be no eloquence in them, attribute it to my many occupations, which have prevented my reading as much as I would gladly have done. Cicero, that fountain of eloquence, when he was one day asked to speak, excused himself on the ground that he had read nothing the day before. The barn must be constantly refilled if it is not to become empty. All that is good in our minds is the fruit of study, and soon withers if it be separated from reading, which is the parent stem. Great indulgence therefore should be shown to us if we have often had to write when we were busy, to be read by others when we had no leisure to read, ourselves. And now enough of excuses, lest too elaborate a defence should rather injure our cause.'
