BOOK III.
I.When Balbus had ended this discourse, then Cotta, with a smile, rejoined, You direct me too late which side to defend; for during the course of your argument I was revolving in my mind what objections to make to what you were saying, not so much for the sake of opposition, as of obliging you to explain what I did not perfectly comprehend; and as every one may use his own judgment, it is scarcely possible for me to think in every instance exactly what you wish.
You have no idea, O Cotta, said Velleius, how impatient I am to hear what you have to say.

For since our friend Balbus was highly delighted with your discourse against Epicurus, I ought in my turn to be solicitous to hear what you can say against the Stoics; and I therefore will give you my best attention, for I believe you are, as usual, well prepared for the engagement.
I wish, by Hercules! I were, replies Cotta; for it is more difficult to dispute with Lucilius than it was with you.

Why so?
says Velleius.
Because, replies Cotta, your Epicurus, in my opinion, does not contend strongly for the Gods: he only, for the sake of avoiding any unpopularity or punishment, is afraid to deny their existence; for when he asserts that the Gods are wholly inactive and regardless of everything, and that they have limbs like ours, but make no use of them, he seems to jest with us, and to think it sufficient if he allows that there are beings of any kind happy and eternal.

But with regard to Balbus, I suppose you observed how many things were said by him, which, however false they may be, yet have a perfect coherence and connection; therefore, my design, as I said, in opposing him, is not so much to confute his principles as to induce him to explain what I do not clearly understand: for which reason, Balbus, I will give you the choice, either to answer me every particular as I go on, or permit me to proceed without interruption.

If you want any explanation, replies Balbus, I would rather you would propose your doubts singly; but if your intention is rather to confute me than to seek instruction for yourself, it shall be as you please; I will either answer you immediately on every point, or stay till you have finished your discourse.
