It is not indeed certain, that the most refined caution will find a proper time for bringing a man to the knowledge of his own failing, or the most zealous benevolence reconcile him to that judgment by which they are detected; but he who endeavours only the happiness of him whom he reproves will always have either the satisfaction of obtaining or deserving kindness; if he succeeds, he benefits his friend; and if he fails, he has at least the consciousness that he suffers for only doing well.
Samuel JohnsonAll discourse of which others cannot partake is not only an irksome usurpation of the time devoted to pleasure and entertainment, but, what never fails to excite resentment, an insolent assertion of superiority, and a triumph over less enlightened understandings. The pedant is, therefore, not only heard with weariness but malignity; and those who conceive themselves insulted by his knowledge never fail to tell with acrimony how injudiciously it was exerted.
Samuel Johnson
