I was not ignorant, Brutus, when I was endeavouring to add to Latin literature the same things which philosophers of the most sublime genius and the most profound and accurate learning had previously handled in the Greek language, that my labours would be found fault with on various grounds. For some, and those too, far from unlearned men, are disinclined to philosophy altogether; some, on the other hand, do not blame a moderate degree of attention being given to it, but do not approve of so much study and labour being devoted to it. There will be others again, learned in Greek literature and despising Latin compositions, who will say that they would rather spend their time in reading Greek; and, lastly, I suspect that there will be some people who will insist upon it that I ought to apply myself to other studies, and will urge that, although this style of writing may be an elegant accomplishment, it is still beneath my character and dignity. And to all these objections I think I ought to make a brief reply; although, indeed, I have already given a sufficient answer to the enemies of philosophy in that book in which philosophy is defended and extolled by me after having been attacked and disparaged by Hortensius.
And as both you and others whom I considered competent judges approved highly of that book, I have undertaken a larger work, fearing to appear able only to excite the desires of men, but incapable of retaining their attention. But those who, though they have a very good opinion of philosophy, still think it should be followed in a moderate degree only, require a temperance which is very difficult in a thing which, when once it has the reins given it, cannot be checked or repressed; so that I almost think those men more reasonable who altogether forbid us to apply ourselves to philosophy at all, than they who fix a limit to things which are in theirnature boundless, and who require mediocrity in a thing which is excellent exactly in proportion to its intensity.
For, if it be possible that men should arrive at wisdom, then it must not only be acquired by us, but even enjoyed. Or if this be difficult, still there is no limit to the way in which one is to seek for truth except one has found it; and it is base to be wearied in seeking a thing, when what we do seek for is the most honourable thing possible. In truth, if we are amused when we are writing, who is so envious as to wish to deny us that pleasure? If it is a labour to us, who will fix a limit to another person's industry? For as the Chremes of Terence does not speak from a disregard of what is due to men when he does not wish his new neighbour
To dig, or plough, or any toil endure:
for he is not in this dissuading him from industry, but only from such labour as is beneath a gentleman; so, on the other hand those men are over scrupulous who are offended by my devoting myself to a labour which is far from irksome to myself.
