Those swift to think are not always secure. - Sophocles

"Far-stretching, endless Time
Brings forth all hidden things,
And buries that which once did shine.
The firm resolve falters, the sacred oath is shattered;
And let none say, "It cannot happen here". "

χάρις χάριν γάρ ἐστιν ἡ τίκτουσ᾽ ἀεί
ὅτου δ᾽ ἀπορρεῖ μνῆστις εὖ πεπονθότος,
οὐκ ἂν γένοιτ᾽ ἔθ᾽ οὗτος εὐγενὴς ἀνήρ.

To err is common
To all men, but the man who having erred
Hugs not his errors, but repents and seeks
The cure, is not a wastrel nor unwise.
