(2) Air is, therefore, twofold in nature-tangible atmosphere and an intangible, volatile substratum which may be termed spiritual air. Fire is visible and invisible, discernible and indiscernible--a spiritual, ethereal flame manifesting through a material, substantial flame. Carrying the analogy further, water consists of a dense fluid and a potential essence of a fluidic nature. Earth has likewise two essential parts--the lower being fixed, terreous, immobile; the higher, rarefied, mobile, and virtual. The general term elements has been applied to the lower, or physical, phases of these four primary principles, and the name elemental essences to their corresponding invisible, spiritual constitutions. Minerals, plants, animals, and men live in a world composed of the gross side of these four elements, and from various combinations of them construct their living organisms.

(10) In this manner you must understand the four Elements, which yet are not four divided Things, or Essences, but one only Essence: And yet there are four Differences, or Distinctions in this Birth; and each Element lies in the other, as in a Chest, and it is its Receptacle, also it is a Member therein. Understand and consider the Ground aright, which follows. The P Sourness is the Matrix, and a Cause of all Things, which in its own Substance is very dark, cold, and as nothing; but the Eternal Deity being there, and speculating or beholding itself in the Sourness, therefore the dark Sourness is desirous after the divine Virtue, and attracts; although there is no Life or Understanding in the Sourness, yet it is the Ground of the first Essence, and the Original whence something comes to be: Here we can search no further into the Ground of the Deity, for it troubles [disturbs, or confounds] us.
