received opinion, we remark, that this definition of beauty, from its associated pleasures, is applicable alike to the deductions of science, to the exercises of imagination, and to the disquisitions of taste. Indeed, as the discoveries of the philosopher, and the truths which he discloses, are both more abiding in their nature, and in their influence more universally important and interesting, it would follow, even on the system of association, that the beauty of scientific truth must be, at least, equally fruitful in pleasurable emotions, as the beauty of any one object in those pursuits to which this system has hitherto been restricted. And that such is actually the case, may be proved by an appeal to the writings and the annals of men of study. The law of gravitation, to take a familiar instance, possesses an essential principle of the beautiful--simplicity. Accordingly, to a mind of any refinement, the abstract contemplation of this theory will ever impart high delight. Yet, how imperfect is the pleasure, and even the beauty, till the mind associates with this simple law, that thereby worlds are governed in their course through boundless space; that by the same discovery, the future generations of rational and immortal beings will be directed in their most useful and loftiest speculations; and to all this magnificence of association, what tender sublimity will be added, by the thought, that the Supreme Father of all has graciously endowed his creatures with powers, and with permission, to discern the secondary laws by which infinite wisdom sees fit to rule in the visible creation!
