uch a Science. The nature of this Analogy, as
well as the value of the discriminations themselves, will be more
clearly seen by glancing at corresponding discriminations in other
spheres.

In the Constitution of the External World, _Something_ is represented,
as we have seen, by the solid and tangible substance which we call
_Matter_, and _Nothing_ by the Expanse of Space.

In the Science of Acoustics, _Sound_, the pure _Phonos_, is the
_Something_, the _Reality_, as it is denominated by Kant, the _Positive_
Factor of Speech. _Silence_ is the relative _Nothing_, the Negation, so
called by Kant, the _Negative_ Factor of Speech. The Silences, or
Intervals of Rest which intervene between Sounds (and also between
Syllables, Words, Sentences, and still larger divisions of Speech), are
only so many successive reappearances of this _negative_ element.
Silence, the Nothing of Sound, is, in fact, in the most radical aspect
of the subject, one entire half or hemisphere or equal Factor of the
whole of Speech or Music. Josiah Warren, the author of a work entitled
'Music as an Exact Science,' is the only writer I have noticed who has
had the discrimination _distinctively_ to recognize Silence as one of
the Elements of the Musical Structure.

_Impliedly_ it is, however, always so recognized. The Silences
intervening between tones _tunewise_, or in respect to altitude, are, in
Musical Nomenclature, denominated _Intervals_. _Timewise_ Silences, or
those which intervene between Tones rhythmically considered, are called
_Rests_. The Intervals of Silence between Syllables and Words, in Oral
Speech, are represented in the printed book by what the Printer calls
_Spaces_, which are _blank_ or _negative_ Types interposed between the
positive Types expressive of Sounds. This term _Space_ or _Spaces_
carries us to the analogous Total Space or Blank Space and intervening
reaches of Space between the Planets, Orbs or Material Worlds, the
former the corresponding _Nothing_ of the total Material Universe of
which these worlds are the _Something_; as exhibited in the
demonstrations of UNIVERSOLOGY.

In the Domain of Optics, covering the Phenomena of Light, Shade and
Color, _Light_ is the _Positive_ Factor or _Something_, and _Darkness_
the _Negative_ Factor or _Nothing_. _Light_ is, therefore, the analogue
of _Sound_, and _Darkness_ the analogue of _Silence_. That is to say,
each of these two, Silence and Darkness, denote the absence, the lack,
