None but a fool worries about things he cannot influence.

Combinations of wickedness would overwhelm the world, by the advantage which licentious principles afford, did not those who have long practised perfidy grow faithless to each other.

The power, indeed, of every individual is small, and the consequence of his endeavours imperceptible, in a general prospect of the world. Providence has given no man ability to do much, that something might be left for every man to do. The business of life is carried on by a general co-operation; in which the part of any single man can be no more distinguished, than the effect of a particular drop when the meadows are floated by a summer shower: yet every drop increases the inundation, and every hand adds to the happiness or misery of mankind.

We consider ourselves as defective in memory, either because we remember less than we desire, or less than we suppose others to remember.

It is as foolish to make experiments upon the constancy of a friend, as upon the chastity of a wife.

The gratification which affluence of wealth, extent of power, and eminence of reputation confer, must be always, by their own nature, confined to a very small number; and the life of the greater part of mankind must be lost in empty wishes and painful comparisons, were not the balm of philosophy shed upon us, and our discontent at the appearances of unequal distribution soothed and appeased.

We must consider how very little history there is--I mean real, authentic history. That certain kings reigned and certain battles were fought, we can depend upon as true; but all the coloring, all the philosophy, of history is conjecture.
