An individual sound, I, has relation, therefore, to _Centre_ and to _Point_ generally. As such it stands representatively for the _Soul_ or _Identity_ or _Central Individuality of Being_--for that which gives to anything its distinctive character, as existing in the _Point_ or the _Unit_, or the _Atom_, or in any Individual Object or Thing from the Atom up to a World and to the Universe as a whole. _Identity_ is, perhaps, the best single term furnished by our Language to signify this basic idea. _Individuality_ approximates the meaning. It is the _pivotal_ notion of Being itself, and has relation, therefore, to Ontology, the Science of Abstract Being. _Essence_ and _Essential Being_ are terms which may also be used in defining it. The Reader should understand, however, that with reference to this Sound, as to those to be hereafter considered, there is no term or terms in any Language which will indicate their meaning _exactly_. The analysis of Ideas upon which UNIVERSOLOGY is based is more fundamental than any which has preceded it. Its Primary Conceptions are, therefore, broader and more inclusive than any former ones which existing terms are employed to denote. In explaining the meaning of these First Elements of Sound, then, as related to the First Elements of Thought, all that is now attempted is to convey as clear a notion of this meaning as is possible with our present terminology, without any expectation that the _precise_ meaning intended will be at once or entirely apprehended. The sound E (_a_ in m_a_te) is likewise a slender, abstract-like, middle-mouth sound; but differs from I in the fact that it is produced by _flattening_ the opening for the Sounding Breath instead of retaining it in a roundish position. The angles of the mouth are drawn asunder, as if pointing outward to the sides of the head, and the sound is, as it were, _elongated in the crosswise direction_, as if a stick or a quill were held in the teeth, the extremities extending outward to the sides. A line, in this direction, is the measurer of BREADTH, which is the Second Dimension of Extension, crossing the Length-line represented by I at right angles. _Side-wise-ness_ is synonymous with RELATION, as one of the Sub-divisions of Reality, or, in other words, of the Realities of Being. _Re-lation_ is, etymologically, from the Latin _re_, BACK or REFLECTED, and _latus_, SIDE; that which mutually and reciprocally re-sides the _Centre_, or furnishes it with sides or _wings_. The Vowel-Sound E (_a_, in m_a_te) is, therefore, the Analogue or Corresponding Representative or Equivalent in the Domain of Sound of that _Fundamental Conception_ which, in respect to Thought, is denominated _Relation_, in respect to Position _Collaterality_ or _Sideness_, and in respect to Dimension _Breadth_ or _Width_.
