As to posterity, I may ask (with somebody whom I have forgot) what has it ever done to oblige me?

The principle of spending money to be paid by posterity, under the name of funding, is but swindling futurity on a large scale

The function of posterity is to look after itself

Think of your forefathers! Think of your posterity!

Posterity gives to every man his true honor. [Lat., Suum cuique decus posteritas rependet.]

A foreign nation is a kind of contemporaneous posterity.
