John LockeAs 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.
