The cause of all the blunders committed by man arises from this excessive self-love. For the lover is blinded by the object loved; so that he passes a wrong judgment on what is just, good and beautiful, thinking that he ought always to honor what belongs to himself in preference to truth. For he who intends to be a great man ought to love neither himself nor his own things, but only what is just, whether it happens to be done by himself, or by another.

A mob is usually a creature of very mysterious existence, particularly in a large city. Where it comes from, or whither it goes, few men can tell. Assembling and dispersing with equal suddenness, it is as difficult to follow to its various sources as the sea itself; nor does the parallel stop here, for the ocean is not more fickle and uncertain, more terrible when roused, more unreasonable or more cruel.
Another argument of hope may be drawn from this-that some of the inventions already known are such as before they were discovered it could hardly have entered any man's head to think of; they would have been simply set aside as impossible.
