Posterity From Oxford’s English Dictionary; “All future generations of people collectively, esp. regarded as the beneficiaries of a particular inheritance, tradition, culture, etc. for (also †in) posterity : for (the sake or good of) future generations; for the future.
For the sake of posterity is often given as the reason for this or that strategy. Politicians love to tell us how we are benefiting or harming future generations – posterity.
Samuel Johnson wrote, “Strange delusion! that can confine all their thoughts to a race of men and women whom they neither know, nor can know; from whom nothing is to be feared, nor anything expected; who cannot even bribe a special jury, nor have so much as a single riband to bestow. The fondness of posterity is a kind of madness which at Rome was almost epidemical, and infected even the women and children.”
Hide your children. Put on your masks. I think the epidemic has begun again. What do we do about it? Or maybe “for posterity” will be the laughing gas of the present century, much enjoyed until the overdose.
