This is what gives such variety to his determinations&mdash;what generally produces such contradiction in his thoughts, his opinions, his will, his actions; in short, in that motion, whether concealed or visible, by which he is agitated. We shall have occasion, in the sequel, to place this truth, at present so much contested, in a clearer light: it will be sufficient for our purpose at present to prove, generally, that every thing in Nature is necessary&mdash;that nothing to be found in it can act otherwise than it does.

Once combined, they have a tendency to conserve themselves in that mode of existence, by virtue of their inert force; in this they cannot succeed, because they are exposed to the continual influence of all other beings, who perpetually and successively act upon them; their change
