In the application of positions as significant pose[166], it is necessary, however, that sculpture proceed with great circumspection, and it has thereby many a difficulty to overcome. On the one hand, no doubt, the reciprocal relation of the members is to be derived from the ideal principle of Spirit; on the other hand, however, this determination from the ideal side ought not to place the particular parts under a mode which contradicts the corporeal structure and the laws of the same, and thereby produce the impression of a constraint imposed on the members, or come into collision with the material of substance, in which sculpture is set the task to execute the artist's conceptions. And, in the third place, the pose must appear wholly spontaneous, as though the body received it of its own initiative, otherwise body and spirit have the appearance of being distinct and separable from each other, and are involved in the relative position of mere direction from one side and purely abstract obedience from the other, whereas both in sculpture ought rightly to constitute one and the same immediately congruent totality. This absence of constraint is here of the first importance. Spirit, as the ideal principle, must throughout transfuse the members, and these latter must in like degree essentially accept spirit and its determination as to the content of its own soul. As to the pose itself and its character, which we may empower to express the just attitude in ideal sculpture, we can readily infer from our previous exposition that it ought not be one wholly referable to change or instantaneous action. The representation of sculpture must produce no effect such as is seen in the case where men, while in the art of motion and action, were turned to stone or frozen by means of Hüon's horn. On the contrary, it is necessary that the posture, although it may without question point to some characteristic action, express for all that merely a beginning and preparation, an intention, or it must indicate the close of an action and a return from the same to the state of repose. The repose and self-subsistency of a spiritual life, which potentially encloses in itself an entire world, is the most suitable aspect for the ideal form of sculpture.
