Observe, in the next place, that Art, whether in the larger or in the smaller sense which we have assigned to it, is the Product of the Combination and Blending of Science with Nature (reflective knowledge with natural impression); or, speaking in the concrete, of the conjunction of man with the outside world; man as the Agent or Actor, and the World or Nature as the Object wrought upon. In the production of Speech, the _phonos_ or mere sound is the natural, unwrought material, which corresponds with the Reality of Nature; and the Meaning or Minding which acts on, articulates and organizes the Sound into Speech, and which _measures_ the sound quantitatively, as in Music, is the Scientific Attribute corresponding with Knowledge. The result of these two in combination is the Art of Speech, generally, and Improvisation or Song as the Fine Art of this Lingual Domain. But passing from the Abstract to the Concrete Domain, Unwrought Natural Sound, bearing its proportion of meaning, furnishes the great basic department of language, which, for the reason that it is basic, is usually regarded as the whole of language, namely, ORAL SPEECH, or SPEECH LANGUAGE, as distinguished from MUSIC AND SONG. Music, on the other hand, is _wrought_ or _measured_ Sound, bearing also its proportion of meaning; a superior language, corresponding with _Science_, from its relation to _measure_, to _numbers_, to _fixed laws_; as Oral Speech corresponds, in its freedom and unconstraint, with Nature. Music and Oral Language united or married to each other constitute SONG, which is then the analogue or type, or Nature's hieroglyph, in this Domain, of Art. We say instinctively the _Art_ of Speech; the _Science_ of Music, and the Art of Singing. In the first instance, Art is used for Natural Performance or Nature; but the whole of speech falling within the domain of art or performance, its lowest or natural division still has some claim to the distinction of an art. The first step of this series, Nature, and the third step, Art, repeat each other by overstepping the second, which is Science, as _Do_ is accordant with _Mi_, but disharmonic with _Re_. It is, therefore, from the instinctual perception of this harmony, that Oral Speech, the basis of Language, the true Nature-department of Language, is still denominated the _Art_ of Speech.
