Art is the path of the creator to his work. The paths, or methods, are ideal and eternal, though few men ever see them, not the artist himself for years, or for a lifetime, unless he come into the conditions. The painter, the sculptor, the composer, the epic rhapsodist, the orator, all partake one desire, namely, to express themselves symmetrically and abundantly, not dwarfishly and fragmentarily. They found or put themselves in certain conditions, as, the painter and sculptor before some impressive human figures; the orator, into the assembly of the people; and the others, in such scenes as each has found exciting to his intellect; and each presently feels the new desire. He hears a voice, he sees a beckoning. Then he is apprised, with wonder, what herds of daemons hem him in. He can no more rest; he says, with the old painter, "By God, it is in me, and must go forth of me." He pursues a beauty, half seen, which flies before him. The poet pours out verses in every solitude. Most of the things he says are conventional, no doubt; but by and by he says something which is original and beautiful. That charms him. He would say nothing else but such things. In our way of talking, we say, 'That is yours, this is mine;' but the poet knows well that it is not his; that it is as strange and beautiful to him as to you; he would fain hear the like eloquence at length. Once having tasted this immortal ichor, he cannot have enough of it, and, as an admirable creative power exists in these intellections, it is of the last importance that these things get spoken. What a little of all we know is said! What drops of all the sea of our science are baled up! and by what accident it is that these are exposed, when so many secrets sleep in nature! Hence the necessity of speech and song; hence these throbs and heart-beatings in the orator, at the door of the assembly, to the end, namely, that thought may be ejaculated as Logos, or Word.
