Among the innumerable mortifications which waylay human arrogance on every side may well be reckoned our ignorance of the most common objects and effects, a defect of which we become more sensible by every attempt to supply it. Vulgar and inactive minds confound familiarity with knowledge and conceive themselves informed of the whole nature of things when they are shown their form or told their use; but the speculatist, who is not content with superficial views, harasses himself with fruitless curiosity, and still, as he inquires more, perceives only that he knows less.
Samuel JohnsonAdvice is offensive, not because it lays us open to unexpected regret, or convicts us of any fault which had escaped our notice, but because it shows us that we are known to others as well as to ourselves; and the officious monitor is persecuted with hatred, not because his accusation is false, but because he assumes that superiority which we are not willing to grant him, and has dared to detect what we desired to conceal.
Samuel Johnson
