As children's inquiries are not to be slighted, so also great care is to be taken, that they never receive deceitful and illuding answers. They easily perceive when they are slighted or deceived, and quickly learn the trick of neglect, dissimulation, and falsehood, which they observe others to make use of. We are not to intrench upon truth in any conversation, but least of all with children; since, if we play false with them, we not only deceive their expectation, and hinder their knowledge, but corrupt their innocence, and teach them the worst of vices.
John LockeThe difference, so observable in men's understandings and parts, does not arise so much from their natural faculties, as acquired habits.
John LockeLet us suppose the mind to be, as we say, white paper, void of all characters, without any ideas; how comes it to be furnished? Whence comes it by that vast store which the busy and boundless fancy of man has painted on it with an almost endless variety? Whence has it all the materials of reason and knowledge? To this I answer, in one word, from experience.
John LockeTill a man can judge whether they be truths or not, his understanding is but little improved, and thus men of much reading, though greatly learned, but may be little knowing.
