Any man may make a mistake; none but a fool will stick to it. Second thoughts are best as the proverb says.
[Lat., Cujusvis hominis est errare; nullius, nisi insipientis, in errore perseverae. Posteriores enim cogitationes (ut aiunt) sapientiores solent esse.]
The gardener plants trees, not one berry of which he will ever see: and shall not a public man plant laws, institutions, government, in short, under the same conditions?
