a power of comparing and judging, we shall see that his liberty is only a similar power, or one derived from this—he chooses the good as he judges of the true, and for the same reason as he deduces a false judgment, he makes a bad choice. What then is the cause that determines his will? It is his judgment. And what is the cause that determines his judgment? It is his intelligent faculty,—by the power of judging. The determining cause lies in himself. If we proceed beyond this point, I know nothing of the matter.
Not that I can suppose myself at liberty not to will my own good, or to will my own evil: but my liberty consists in this very circumstance, that I am incapable to will anything but what is useful to me, or at least what appears so, without any foreign object interfering in my determination. Does it follow from hence that I am not my own master because I am incapable of assuming another being, or of divesting myself of what is essential to my existence?
The principle of all action lies in the will of a free being. We can go no farther in search of its source. It is not the word liberty that has no signification; it is that of necessity. To suppose any act or effect, which is not derived from an active principle, is indeed to suppose effects without a cause. Either there is no first impulse, or every first impulse can have no prior cause; nor can there be any such thing as will without liberty. Man is, therefore, a free agent, and as such animated by an immaterial substance. This is my third article of faith. From these three first you may easily deduce all the rest, without my continuing to number them.
If man be an active and free being, he acts of himself.
