Song is the _measure of the strain_ and the _mingle of the bawl_ again commingled with each other, in a composite blending of _The Measured_ and _The Free_. As the Composity of that which has for its numerical type Two, with that which has for its numerical type One, the proper numerical type of Song is Three; or thus: _Language._ _Number._ 3. Song, THREE. 2. Music, TWO. 1. Oral Speech, ONE. These numerical analogues can only be adverted to here, and their meaning may not be very distinctly perceived. Their full exposition and that of their immense importance as principles and guides in the domain of analogy must be treated of elsewhere. Rhythm is the _measure_ of the _strain_. Music is the _mingled measure_ of _many strains_. Song is the higher mingling of _music_ with the _bawl_ (the phonos, or the material of Oral Speech). _Measure_ is the analogue of _Science_, and hence Music is another such analogue. _Men_-s, MIND, and _men_-sura, MEASURE, are etymologically cognate words; so the English words MEAN-ing, THE MIND _that is in a thing_, and MEAN, the average or measure, or the dia-_meter_, or through-_measure_ of a thing. Again, the concrete analogue of Science (_Knowledge_, _Mind_, _The Abstract,_ etc.) is, as we have seen, Man. MEN-s, MAN, _hu_-MAN-us, are again, probably, etymologically cognate to _homo_, _hominis_, _hoc men_-s, as _hodie_ is to _hoc_ or _haec dies_. The Line or Cord is the instrument of _measuring_, and as such is again the type of Science, as the Ball or Globe is the type of Nature; the Line, the type of _strictness_, _straightness_, _stretchedness_, _exactness_; and the lump or aggregative form, that of Freedom from Constraint, Solution, as of the water-drop, and of Absolute-ness (_ab_, FROM, and _solvere_, TO FREE). THE RELATIVE repeats THE ABSTRACT; and THE ABSOLUTE, in Philosophy, repeats THE CONCRETE. The Relative has for its type _Two_, or _di-termination_ (_dis_ or _di_, _Two_, and _termini_, ENDS); and the Absolute has for its type _One_, [Greek: to hen] of the Greeks. EXISTENCE, embodying The Absolute _and_ The Relative; the _one_ and the _two_; has for its type Three; and the all-sided aspect of Universal Being which distinguishes and yet combines these _three_ aspects of Being, is TRI-UNITY, OR THE THREE IN ONE. The Trinism, or third story of ascension in the constitution of things, again divides into Two Branches, the first of which accords with Duism (_music_, _line_, _science_, _mind_, _man_), and the second with Unism (_oral speech_, _globe_, _nature_, _world_).
