subject to his sovereign; a worse father to his children; a more unkind husband; a more faithless friend? Motion, then, is co-eternal with matter: from all eternity the particles of the universe have acted and reacted upon each other, by virtue of their respective energies; of their peculiar essences; of their primitive elements; of their various combinations. These particles must have combined in consequence of their affinity; they must have been either attracted or repelled by their respective relations with each other; in virtue of these various essences, they must have gravitated one upon the other; united when they were analagous; separated when that analogy was dissolved, by the approach of heterogeneous matter; they must have received their forms, undergone a change of figure, by the continual collision of bodies. In a material world the acting powers must be material: in a whole every part of which is essentially in motion, there is no occasion for a power distinguished from itself; the whole must be in perpetual motion by its own peculiar energy. The general motion, as we have elsewhere proved, has its birth from the individual motion, which beings ever active must uninterruptedly communicate to each other. Thus every cause produces its effect; this effect in its turn becomes a cause, which in like manner produces an effect; this constitutes the eternal chain of things, which although perpetually changing in its detail, suffers no change in its whole. Theology, after all, has seldom done more than personify this eternal series of motion; the principle of mobility inherent to matter: it has clothed this principle with human qualities, by which it has rendered it unintelligible: in applying these properties, they have taken no means of understanding how far they were suitable or not: in their eagerness to make them assimilate, they have extended them beyond their own conception; they have heaped them together without any judgment; and they have been surprised when these qualities, contradictory in themselves, did not enable them satisfactorily to account for all the phenomena they beheld; from thence they have wrangled; accused each other of imbecility; yet infuriated themselves against whoever had the temerity to question that which they did not themselves understand; in short, they have acted like a man who should insist that all other men should have precisely the same vision that he himself had dreamed.
