The æsthetic state represents an overflow of means of communication as well as a condition of extreme sensibility to stimuli and signs. It is the zenith of communion and transmission between living creatures; it is the source of languages. In it, languages, whether of signs, sounds, or glances, have their birthplace. The richer phenomenon is always the beginning: our abilities are subtilised forms of richer abilities. But even to-day we still listen with our muscles, we even read with our muscles.
Every mature art possesses a host of conventions as a basis: in so far as it is a language. Convention is a condition of great art, not an obstacle to it.... Every elevation of life likewise elevates the power of communication, as also the understanding of man. The power of living in other people's souls originally had nothing to do with morality, but with a physiological irritability of suggestion: "sympathy," or what is called "altruism," is merely a product of that psycho-motor relationship which is reckoned as spirituality (psycho-motor induction, says Charles Féré). People never communicate a thought to one another: they communicate a movement, an imitative sign which is then interpreted as a thought.

Compared with music, communication by means of words is a shameless mode of procedure; words reduce and stultify; words make impersonal; words make common that which is uncommon.

It is exceptional states that determine the artist—such states as are all intimately related and entwined with morbid symptoms, so that it would seem almost impossible to be an artist without being ill.
The physiological conditions which in the artist become moulded into a "personality," and which, to a certain degree, may attach themselves to any man:—
(1) Intoxication, the feeling of enhanced power; the inner compulsion to make things a mirror of one's own fulness and perfection.
(2) The extreme sharpness of certain senses, so that they are capable of understanding a totally different language of signs—and to create such a language (this is a condition which manifests itself in some nervous diseases); extreme susceptibility out of which great powers of communion are developed; the desire to speak on the part of everything that is capable of making-signs; a need of being rid of one's self by means of gestures and attitudes; the ability of speaking about one's self in a hundred different languages—in fact, a state of explosion.
One must first imagine this condition as one in which there is a pressing and compulsory desire of ridding one's self of the ecstasy of a state of tension, by all kinds of muscular work and movement; also as an involuntary co-ordination of these movements with inner processes (images, thoughts, desires)—as a kind of automatism of the whole muscular system under the compulsion of strong stimuli acting from within; the inability to resist reaction; the apparatus of resistance is also suspended. Every inner movement (feeling, thought, emotion) is accompanied by vascular changes, and consequently by changes in colour, temperature, and secretion. The suggestive power of music, its "suggestion mentale."
