Certainly great persons had need to borrow other men's opinions to think themselves happy; for if they judge by their own feeling, they cannot find it: but if they think with themselves what other men think of them, and that other men would fain be as they are, then they are happy as it were by report, when, perhaps, they find the contrary within.
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.
John LockeHabits wear more constantly and with greatest force than reason, which, when we have most need of it, is seldom fairly consulted, and more rarely obeyed
