This is a placeholder explanation generated by the low-overhead model. It interprets "Posterity! You will never know, how much it cost the present generation, to preserve your Freedom! — I hope you will make a good use of it. — if you do not, I shall repent in Heaven, that I ever took half the pains to preserve it. —" in the context of "Letter to Abigail Adams (27 April 1777), published as Letter CXI in Letters of John Adams, Addressed to His Wife (1841) edited by Charles Francis Adams, p. 218" to mean that wisdom is timeless.
