neither solitary good nor solitary truth, may be illustrated and at the same time confirmed by various considerations; as by the following: that there is no essence without a form, nor any form without an essence; for good is an essence or _esse_; and truth is that by which the essence is formed and the _esse_ exists. Again in a man (_homo_) there are the will and the understanding. Good is of the will, and truth is of the understanding; and the will alone does nothing but by the understanding; nor does the understanding alone do anything but from the will. Again, in a man there are two fountains of bodily life, the heart and the lungs. The heart cannot produce any sensitive and moving life without the respiring lungs; neither can the lungs without the heart. The heart has relation to good, and the respiration of the lungs to truth: there is also a correspondence between them. The case is similar in all the things of the mind and of the body belonging to him; but we have not leisure to produce further confirmations in this place; therefore the reader is referred to the ANGELIC WISDOM CONCERNING THE DIVINE PROVIDENCE, n. 3-16, where this subject is more fully confirmed and explained in the following order: I. That the universe with all its created subjects, is from the divine love by the divine wisdom; or, what is the same thing, from the divine good by the divine truth. II. That the divine good and the divine truth proceed as a one from the Lord. III. That this one, in a certain image, is in every created thing. V. That good is not good, only so far as it is united with truth; and that truth is not truth, only so far as it is united with good. VII. That the Lord doesn't suffer that any thing should be divided; wherefore a man must either be in good and at the same time in truth, or in evil and at the same time in falsehood: not to mention several other considerations.
