of an inclusive meaning. That is to say, it integrates in its
signification, all that is inherently signified by all the other Vowels.

While, however, AU is practically and usually the Representative,
Analogue or Equivalent, in the Domain of Language, of Universal Reality
among the Elements of Being, this is so _only in practice_.
_Theoretically_, the Diphthong best adapted to represent this Idea is
AO; the A and the O being, in a supreme sense, the two most prominent or
leading Vowels. But it is a little difficult to retain the Organs of
Utterance in the position which they must assume in order to pronounce
these two Vowel-Sounds in conjunction. The organs readily and naturally
slide into the easier position in which they utter AU. This is
correspondential with the difficulty always experienced in adhering to
_Pure Theory_ (O); and the natural tendency to glide from it, as ground
too high for permanent occupation, into the more accommodating Domain of
the _Practical_ (U).

The Full Scale of Vowel Sounds coupled with the Full Scale of the
(Indeterminate) Realities of Universal Being is, therefore, as follows:

1. SOUNDS. 2. REALITIES OF BEING.

1. I, i (ee as in feel). ENTITY or IDENTITY (Centre, Least
Element, Essential Being,
Individuality).

2. E, e (a as in mate). RELATION (Sideness, Collaterality,
Adjectivity).

3. _A_, _a_ (a as in mare). UNSUBSTANTIALITY (Thinness, Ghost,
Apparition).

4. A, a (a as in fa-ther). SUBSTANCE (Thickness, Materiality,
Richness, Goodness).

5. _O_, _o_ (aw as in awful). SPACE (Volume, Expansion).

6. _U_, _u_ (u as in curd). TIME (Flux, Flow).

7. O, o (o as in noble). LIGHT (Reflection, Parity, Clearness,
Theory).

8. U, u (oo as in fool). SHADE (Retiracy, Turbidity, Mixture,
Practice).

9. IU, iu (YIU), (u in union, use). CONJUNCTION (Event, Joining).

10. AI, ai (ah-ee, i in fine). BASIC REALITY (Ground of Existence).

11. OI, oi (aw-ee, oy in boy). AERIAL or ASCENDING REALITY (Loft,
Loftiness).
