Every man naturally persuades himself that he can keep his resolutions, nor is he convinced of his imbecility but by length of time and frequency of experiment.

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.

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.

Books, says Lord Bacon, can never teach us the use of books; the student must learn by commerce with mankind to reduce his speculations to practice.

He is not only dull himself, but the cause of dulness in others.

The time will come to every human being when it must be known how well he can bear to die.
