Now we have argued that beauty is most probably associated initially with sex, since with sex the idea of personal relationship first arises. Our main thesis would not however be invalidated if it could be shown that a vague intuition of relation with inorganic or non-personal objects arose first. The intuition of relation may well have several separate starting points. Only, in this case, the reciprocal element would be absent (though its lack might not be felt except as a vague dissatisfaction) and could only arise when the sex-relation was the subject of a similar intuition. But most likely the intuition of relation did arise with sex, and, since our argument is concerned to show that ultimately the intuition of beauty leads to the expression of mutual relationship--love--and finds there the explanation both of its peculiar quality, and of the creative longing it produces, we will confine our argument mainly to this aspect. Now if this be so, the sense of beauty is likely to be associated in its earliest stages with sight, and only in a secondary degree with sound, in the mating-call and in the beginnings of language. This is borne out by the fact that music usually lags behind, and is more primitive in expression than the visual arts--personal ornamentation and even decoration of objects. True, the first formal _expression_ is likely to be in sound--in the beginnings of language. The dynamic relation between persons maybe accompanied and expressed throughout by speech. But at this primitive level it will be a very limited intuition or understanding that is expressed, and moreover, an intuition that is based on visual stimuli. We may therefore leave the question of language for the present. Its importance in the earlier stages is mainly practical. Through sight (when the stage of simple chemiotaxis is passed) arises the perception of desirability in the opposite sex[37], which is the animal starting-point from which love is evolved. This desirability and this relation are expressed to the self, and this expression is beauty in its humblest beginning. Then, later, the creative aspect enters into consciousness. At first it was satisfied, unconsciously, in mating; but soon this unconscious satisfaction is felt to be inadequate. The representative process begins.
