“There is without all doubt,” as has been justly observed, “a chain of the thoughts of human kind, from the origin of the world down to the moment at which we exist,--a chain not less universal than that of the generation of every being that lives. Ages have exerted their influence on ages; nations on nations; truths on errors; errors on truths.” In conformity with this idea of the generation of thought, I may remark, that we are in possession of opinions,--which, perhaps, regulate our life in its most important moral concerns, or in all its intellectual pursuits,--with respect to which, we are as ignorant of the original authors, by whom they have been silently and imperceptibly transmitted to us from mind to mind, as we are ignorant of those ancestors, on whose existence in the thousands of years which preceded our entrance into the world, our life itself has depended, and without whom, therefore, _we_ should not have been. The unlimited transmission of thought, which the invention of language allows, brings the universe of _mind_ into that point of view, in which an eloquent living French author has considered the _physical_ universe,--as exhibiting, at once, all its splendid varieties of events, and uniting, as it were, in a single moment the wonders of eternity. “Combine,” says he, “by your imagination, all the fairest appearances of things. Suppose that you see, at once, all the hours of the day, and all the seasons of the year,--a morning of spring and of autumn,--a night brilliant with stars, and a night obscure with clouds,--meadows, enamelled with flowers,--fields, waving with harvest,--woods, heavy with the frosts of winter,--you will then have a just notion of the spectacle of the universe. Is it not wondrous, that while _you_ are admiring the sun, who is plunging beneath the vault of the west, _another_ observer is beholding him as he quits the regions of the east,--in the same instant reposing, weary, from the dust of the evening, and awaking, fresh and youthful, in the dews of morn! there is not a moment of the day, in which the same sun is not rising, shining in his zenith, and setting on the world! or, rather, our senses abuse us, and there is no rising, nor setting, nor zenith, nor east, nor west; but all is one fixed point, at which every species of light is beaming at once from the unalterable orb of day.” In like manner,--If I may venture to consider the phenomena of the mind in the same fanciful point of view,--every moment may be said to be exhibiting the birth, and progress, and decay of thought. Infancy, maturity, old age, death, are mingled, as it were, in one universal scene. The opinions which are perishing in one mind, are rising in another; and often, perhaps, at the last fading ray of the flame of genius, that may have almost dazzled the world with excess of brilliancy, some star may be kindling, which is to shine upon the intellectual universe with equal light and glory:--[78]
