[2.] _Created_ spirit-life. And here we make another subdivision. (_a_) The life of created _immortal_ spirit. This is a rational, intelligent entity, representing the spirit of man and of unembodied, created intelligences above him. This spirit God created as it pleased him--"in his own likeness"--a living, indestructible essence; and, as I suppose, its essence and its life the same. (_b_) The life of created _mortal_ spirit, as the spirit of the beast. Of the intrinsic essence of this spirit, we are also necessarily ignorant. Yet, of its attributes we know that it has _consciousness_, _sensibility_, and _will_. Of its life we know as little as of its essence; both of which, however, as I conjecture, are also one and the same--the spirit substance being itself essentially vital. (2.) We pass next to _moral_ life. This life is identical with _holiness_--the very opposite of that defilement that characterizes moral _death_, which is a state of _sin_. But let me again subdivide. [1.] As to the moral life of _God_, it consists in his infinite moral purity--his _veracity_, _justice_ and _benevolence_ or _love_--qualities which, in their combination make up his holiness. [2.] The moral life of _man, as also of other rational creatures_. This consists in his _sympathy of spirit with God_ in respect to those pure qualities which constitute the Divine holiness. (3.) Finally, there is _electric_ or _physical life_. But here again there are varieties. [1.] There is _animal_ life, as of man and the lower animals. This I have already represented as consisting in the electro-vital force. [2.] _Vegetable_ life. This is another modification of the same essential principle--electro-vitality. But now, to return to the _physical_ or _animal life of man_--the electro-vital element. While this is in such _immediate_ relation to the visible body on the one hand, it holds, also, on the other hand, an _immediate_ relation to the mental part, both of man and of the other animated beings of earth. It serves to transmit, through the nervous system to the mind, all sensations and impressions from the outer world. It, moreover, receives from the mind the action of its volitions and imaginary conceptions, and conveys through the nerves the impressions or impulsions thus obtained to the various parts of the body, and there secures the fulfillment of the mind's behests. It appears to be only in this way that communication is had between the mind and its outer body. The natures of spirit and of gross matter are so totally unlike, that it seems impracticable for the mind and body to come into _immediate_ mutual relation, or to act reciprocally, without the aid of a _medium_--ethereal, semi-material and semi-spiritual, such as is the electro-vital fluid. And the Creator has accordingly provided this mysterious, invisible medium between the two, and thus, in a degree, extended man's likeness to himself by making him _a trinity in unity_.
