“Sir, very few people reach posterity. Who amongst us may arrive at that destination I presume not to vaticinate. Posterity is a most limited assembly. Those gentlemen who reach posterity are not much more numerous than the planets.”

"My Beef With Ann Coulter" in The Daily Beast (9 March 2009) http://www.thedailybeast.com/blogs-and-stories/2009-03-09/my-beef-with-ann-coulter/
Context: Certain individuals continue to perpetuate negative stereotypes about Republicans. Especially Republican women. Who do I feel is the biggest culprit? Ann Coulter. I straight up don’t understand this woman or her popularity. I find her offensive, radical, insulting, and confusing all at the same time. But no matter how much you or I disagree with her, the cult that follows Coulter cannot be denied. She is a New York Times best-selling author and one of the most notable female members of the Republican Party. She was one of the headliners at the recent CPAC conference (but when your competition is a teenager who has a dream about the Republican Party and Stephen Baldwin, it’s not really saying that much).
Coulter could be the poster woman for the most extreme side of the Republican Party. And in some ways I could be the poster woman for the opposite. I consider myself a progressive Republican, but here is what I don’t get about Coulter: Is she for real or not? Are some of her statements just gimmicks to gain publicity for her books or does she actually believe the things she says? Does she really believe all Jewish people should be “perfected” and become Christians? And what was she thinking when she said Hillary Clinton was more conservative than my father during the last election? If you truly have the GOP’s best interests at heart, how can you possibly justify telling an audience of millions that a Democrat would be a better leader than the Republican presidential candidate? (I asked Ann for comment on this column, including many of the above questions, but she did not answer my request.)

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.

Trajan's Oriental Policy

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.
