It is for little souls, that truckle under the weight of affairs, not to know how clearly to disengage themselves, and not to know how to lay them aside and take them up again.
Michel de MontaigneLearning is not to be tacked to the mind, but we must fuse and blend them together, not merely giving the mind a slight tincture, but a thorough and perfect dye. And if we perceive no evident change and improvement, it would be better to leave it alone; learning is a dangerous weapon, and apt to wound its master if it be wielded by a feeble hand, and by one not well acquainted with its use.
Michel de Montaigne
