“Posterity has justified more the policy of conquest than that of concession.”
The Provinces of the Roman Empire, From Caesar to Diocletian 1854-6
Context: It is not meant to be denied that in a policy of conquest consistency is a dangerous praise, and that Trajan after his fashion yielded in these enterprises more than was reasonable to the effort after external success, and went beyond the rational; but wrong is done to him when his demeanor in the East is referred to blind lust of conquest. He did what Caesar would have done had he lived. His policy is but the other side of that of Nero's statesmen, and the two are as opposite, as they are equally consistent and equally warranted. Posterity has justified more the policy of conquest than that of concession.

In a debate in the Irish House of Commons on the vote of a grant which was recommended by Sir John Parnell, Chancellor of the Exchequer, as one not likely to be felt burdensome for many years to come, it was observed in reply that the House had no right to load posterity with a debt for what could in no degree operate to their advantage. This quotation was Sir Boyle's response.

Alternate translation: We go to great pains to alter life for the happiness of our descendants and our descendants will say as usual: things used to be so much better, life today is worse than it used to be.
Мы хлопочем, чтобы изменить жизнь, чтобы потомки были счастливы, а потомки скажут по обыкновению: прежде лучше было, теперешняя жизнь хуже прежней.
