Hey, our guess was not wrong after all.Poster Calliope at The Fuselage pointed out previously that the quote may be from George Santayana and is often wrongly attributed to Plato. I looked up Santayana, and there are some interesting things mentioned on his wiki page:
It goes: μόνοι τὸ τοῦ πολέμου τέλος ἑωράκασι '...only they have seen the end of the war'. There
By the way: this quote is not from Plato. It is a translation into Ancient Greek.
O world, thou choosest not the better part!
It is not wisdom to be only wise,
And on the inward vision close the eyes,
But it is wisdom to believe the heart.
Columbus found a world, and had no chart,
Save one that faith deciphered in the skies;
To trust the soul’s invincible surmise
Was all his science and his only art.
And intriguingly in the context of the tapestry:
Happiness is the only sanction of life; where happiness fails, existence remains a mad and lamentable experiment.I'm so glad there are people who know how to read Ancient Greek!
That life is worth living is the most necessary of assumptions and, were it not assumed, the most impossible of conclusions.
Fanaticism consists in redoubling your efforts when you have forgotten your aim.
Progress, far from consisting in change, depends on retentiveness. When change is absolute there remains no being to improve and no direction is set for possible improvement: and when experience is not retained, as among savages, infancy is perpetual. Those who cannot remember the past are condemned to repeat it.
