From whence it is obvious to conclude that, since our Faculties are not fitted to penetrate into the internal Fabrick and real Essences of Bodies; but yet plainly discover to us the Being of a GOD, and the Knowledge of our selves, enough to lead us into a full and clear discovery of our Duty, and great Concernment, it will become us, as rational Creatures, to imploy those Faculties we have about what they are most adapted to, and follow the direction of Nature, where it seems to point us out the way.
John LockeDefects and weakness in men's understandings, as well as other faculties, come from want of a right use of their own minds; I am apt to think, the fault is generally mislaid upon nature, and there is often a complaint of want of parts, when the fault lies in want of a due improvement of them.
John LockeWe are all a sort of chameleons, that still take a tincture from things near us: nor is it to be wondered at in children, who better understand what they see, than what they hear.
