It is the just doom of laziness and gluttony to be inactive without ease and drowsy without tranquility.

All history was at first oral.

In order that all men may be taught to speak truth, it is necessary that all likewise should learn to hear it; for no species of falsehood is more frequent than flattery, to which the coward is betrayed by fear, the dependent by interest, and the friend by tenderness: those who are neither servile nor timorous are yet desirous to bestow pleasure; and, while unjust demands of praise continue to be made, there will always be some whom hope, fear, or kindness will dispose to pay them.

Human 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.

That distrust which intrudes so often on your mind is a mode of melancholy, which, if it be the business of a wise man to be happy, it is foolish to indulge; and if it be a duty to preserve our faculties entire for their proper use, it is criminal. Suspicion is very often an useless pain.

There is in this world no real delight (excepting those of sensuality), but exchange of ideas in conversation.

There must always be some advantage on one side or the other, and it is better that advantage should be had by talents than by chance.
