Quack: A boastful pretender to arts which he does not understand. A vain boastful pretender to physick; An artful, tricking practitioner in physick.
Samuel JohnsonBooks are faithful repositories, which may be awhile neglected or forgotten; but when they are opened again, will again impart their instruction: memory, once interrupted, is not to be recalled. Written learning is a fixed luminary, which, after the cloud that had hidden it has passed away, is again bright in its proper station. Tradition is but a meteor, which, if once it falls, cannot be rekindled.
Samuel JohnsonEvery one should consider himself as intrusted not only with his own conduct, but with that of others; and as accountable, not only for the duties which he neglects, or the crimes that he commits, but for that negligence and irregularity which he may encourage or inculcate. Every man, in whatever station, has, or endeavours to have his followers, admirers, and imitators, and has therefore the influence of his example to watch with care.
Samuel JohnsonIt may be observed in general that the future is purchased by the present. It is not possible to secure distant or permanent happiness but by the forbearance of some immediate gratification. This is so evidently true with regard to the whole of our existence that all precepts of theology have no other tendency than to enforce a life of faith; a life regulated not by our senses but by our belief; a life in which pleasures are to be refused for fear of invisible punishments, and calamities sometimes to be sought, and always endured, in hope of rewards that shall be obtained in another state.
