We infer from analogy, that these laws always have been, are, and always will be, invariably the same; and that they prevail alike in every portion of God’s universe. We so judge, because we believe the existing order of things to be the wisest and the best. We know that the physical laws actually do prevail alike in every part of our world, and as far beyond it, as the highest helps of astronomy can aid our researches into the depths of immensity. Is it not probable, that if we could investigate the system, as far as the utmost stretch of thought, we should find no point, where the laws of gravity, light, heat and motion do not prevail; where the sentient beings are not restricted to the same moral relations, as in our world? Wherever the empire of science has extended, we note these laws equally prevalent, in a molecule and a world, and from the lowest order of sentient beings up to man. The arrangement of the great whole, it should seem, must be a single emanation from the same wisdom and will, perfectly uniform throughout the whole empire. What an impressive motive to study these laws, and conform to them, is it, to know, that they are as irresistible, as the divine power, as universal, as the divine presence, as permanent as the divine existence;--that there is no evading them, that no art can disconnect misery from transgressing them, that no change of place or time, that not death, nor any transformation which our conscious being can undergo, will, during the revolutions of eternity, dispense any more with the necessity of observing these laws, than during our present transitory existence in clay! I need not dwell a moment upon the proofs of the absolute identity of the physical laws. No one need be told, that a ship floats, water descends, heat warms, and cold freezes, and that all physical properties of matter are the same over the globe. We shall only show by a few palpable examples, that our system is arranged in conformity to the organic laws. Every discovery in the kingdom of animated nature developes new instances.
