315. [305.] 3) In each kingdom there are two degrees-two in the natural, two in the spiritual, two in the celestial. Thus in the three kingdoms there are six degrees. [306.] All these degrees are discrete or discontinuous, and we call them degrees of height. [307.] Discrete degrees stand in relation to each other like thought and speech, or like an affection of the heart and a gesture, or like an affection of the mind and an expression of the face. Or, in the material world, like the ether and the air, or like a sinew and the fibers of which it consists. All composite entities throughout the natural world and in the spiritual world are of such a character, and they consist of two or three such degrees in their proper sequence. We call these degrees prior and subsequent, higher and lower, inner and outer; and in general they stand in relation to each other like cause and effect, or like an essence and its embodiment or aggregate of essences, or like an elementary substance and its derivative compound or amalgamation of elementary substances.
