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.

There lurks, perhaps, in every human heart a desire of distinction, which inclines every man first to hope, and then to believe, that Nature has given him something peculiar to himself.

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.

The chief art of learning, as Locke has observed, is to attempt but little at a time. The widest excursions of the mind are made by short flights frequently repeated; the most lofty fabrics of science are formed by the continued accumulation of single propositions.

Friendship, like love, is destroyed by long absence, though it may be increased by short intermissions.

The business of life is to go forward; he who sees evil in prospect meets it in his way, and he who catches it by retrospection turns back to find it. That which is feared may sometimes be avoided, but that which is regretted to-day may be regretted again to-morrow.

A man has no more right to say an uncivil thing than to act one; no more right to say a rude thing to another than to knock him down.
