MARCUS: Away, then, with all that almost old-womanish twaddle about untimely death being a miserable thing. What time pray? Nature’s? But she gives life on loan, as one might lend money — without fixing beforehand a day of repayment. What ground is there for complaint, then, if she ask for it back whenever she pleases? That was the condition on which you received it.

[Pellantur ergo istae ineptiae paene aniles, ante tempus mori miserum esse. Quod tandem tempus? Naturaene? At ea quidem dedit usuram tamquam pecuniae nalla praestituta die. Quid est igitur quod querare, si repetit,cum volt? Ea enim condicione acceperas.]

Away then with these Sayings, little better than fit for old Wives; that it is miserable to dye before ones time: What time, I pray? that of Nature? Now she hath lent Life, as Cash, at no day certain of payment prefix'd; what reason then have you to murmur, if she calls in her own when she pleaseth, since you receiv'd it upon that condition?
[tr. Wase (1643)]

Away then with those follies that speak the old woman; that it is miserable to die before our time. What time do you mean! That of nature? She lent you life, as money, without fixing a time for its payment. Have you any grounds of complaint then, that she recalls it at her pleasure? For you received it on these terms.
[tr. Main (1824)]

Away, then, with that impertinence, stamped almost with dotage, that it is hard to die before the time. What time, at length? Nature's? But nature granted the loan of it, as of money, without a day prefixed; then what hast thou to com- plain of, if she require her due when she please? for it was accepted by thee on this condition.
[tr. Otis (1839)]

Away, then, with those follies which are little better than the old women's dreams, such as that it is miserable to die before our time. What time do you mean? That of nature? But she has only lent you life, as she might lend you money, without fixing any certain time for its repayment. Have you any grounds of complaint, then, that she recalls it at her pleasure? for you received it on these terms.
[tr. Yonge (1853)]

Away then with the almost anile folly that it is a wretched thing to die before one’s time. What time, forsooth? The appointed time of Nature? But Nature has given us the use of life, as we might have that of money, with no day fixed for repayment. What reason for complaint is there, then, if she demands it at her pleasure? It was on that condition that we received it.
[tr. Peabody (1886)]

[...] Nature has bestowed on us life at interest like money, no day being fixed for its repayment. [...]
[tr. Taylor/Hunt (1916)]

So let those foolish ideas, almost old wives' tales, that it is wretched to die before one's time be rejected. What time? Nature's? But she made a loan of life, like one of money, with no fixed term. So what grounds have you for complaining if she reclaims it when she likes? That was the condition on which you had taken the loan.
[tr. Douglas (1985)]

Away with these old wives' tales, with this idea that it's terrible to die before one's time! What time? The time of nature? It made us a loan without a due date. Why complain if it seeks repayment at a time of its choosing? After all, you accepted the loan on those terms!
[tr. Habinek (1996)]

So let such follies, almost old wives' tales, claming that it is wretched to die before our time, be rejected. What is this "time," I ask? Nature's? But it is nature that has made a loan of life, liek one of money, with no fixed day of repayment. What grounds, then, do you have for complaint, if nature calls in this loan whenever it wants? Those were the terms on which you had taken the loan.
