The two Mandela lines are doing opposite jobs
“Education is the most powerful weapon” is about the long game — a claim that a school is a more serious instrument than it looks. “It always seems impossible until it’s done” is about the next fortnight, and about how reliably the feeling of impossibility misreports the actual difficulty. A graduation needs both, because it is a room full of people who have just finished something that once looked impossible and are about to start something that looks worse.
Four centuries, and almost all of it spoken aloud
From Francis Bacon in 1597 to 2005, and an unusual number of these lines come from addresses rather than from books — Jobs at Stanford, Mandela in Johannesburg, King as an undergraduate. That is the room's distinguishing feature and the reason it verifies better than most: a speech has a date and a place, and somebody wrote it down. Seven of the fifteen carry an exact citation.
What is the best quote for a graduation card?
Steve Jobs’s “your time is limited, so don’t waste it living someone else’s life”, from his 2005 Stanford commencement address, is the most quoted for good reason. If you want something shorter, Mandela’s “it always seems impossible until it’s done” fits on a card and says more.
Did Aristotle say the roots of education are bitter?
It is credited to him almost everywhere but cannot be traced to anything he wrote. Diogenes Laërtius reports something like it centuries later, so the label here is attributed rather than sourced.
Did Benjamin Franklin say “An investment in knowledge pays the best interest.”?
A modern tidying of Franklin rather than Franklin. His own maxim runs “If a man empties his purse into his head, no man can take it from him”; the “investment” phrasing first shows up in a school grammar book of 1909. It is filed here as attributed to Benjamin Franklin, which means widely credited and not traced to a primary source.
Did Victor Hugo say “He who opens a school door, closes a prison.”?
Credited to Hugo since the nineteenth century, but the earliest citations name someone else: the French education minister Victor Duruy, in 1865 — ouvrir une école, c’est fermer une prison. It is filed here as attributed to Victor Hugo, which means widely credited and not traced to a primary source.
Did John D. Rockefeller say “Don’t be afraid to give up the good to go for the great.”?
Rockefeller died in 1937. The earliest known appearance of this line is 1993, crediting the country singer Kenny Rogers; his name was swapped for Rockefeller’s later. It is filed here as attributed to John D. Rockefeller, which means widely credited and not traced to a primary source.
