192. That these degrees are homogeneous, that is, of the same character and nature is evident from what has just been said. The motor fibres of muscles, least, greater and greatest, are homogeneous. Woody filaments from least things to their composite are homogeneous. Similarly are stony and metallic particles. The organic substances which are receptacles and abodes of thoughts, from simplest things to their general aggregate which is the brain, are homogeneous. Atmospheres, from pure ether to air, are homogeneous. Degrees of heat and light in series, according to the degrees of atmospheres, are homogeneous; and hence also degrees of love and wisdom are homogeneous. Those things which are not of the same character and nature are heterogeneous, and do not harmonize with homogeneous things; thus they cannot form discrete degrees with them, but only with their own which are of the same character and nature, with which they are homogeneous.
