Though the wisdom or virtue of one can very rarely make many happy, the folly or vice of one man often make many miserable.
Samuel JohnsonHuman experience, which is constantly contradicting theory, is the great test of truth. A system, built upon the discoveries of a great many minds, is always of more strength, than what is produced by the mere workings of any one mind, which, of itself, can do very little. There is not so poor a book in the world that would not be a prodigious effort were it wrought out entirely by a single mind, without the aid of prior investigators.
Samuel JohnsonA man who always talks for fame never can be pleasing. The man who talks to unburthen his mind is the man to delight you.
Samuel Johnson
