The page discusses how parts of an image should coordinate to efficiently express a unified action, either physical or mental, reflecting the spirit of the mover about a certain object. Movements should resemble either a fool’s disorganized actions or a madman's intense gestures if not properly aligned. It also highlights that each limb must perform its function, with no movement added where there is none, and the importance of portraying an image without errors to demonstrate obedience to its intended design.
The Human Figures, Etc. 285
Various activities appear to converge, where a part of an image seems to do something different, which is not directly related to the action that was assigned and is proper, as noted in its place. However, in the average or complete movement, everything operates simultaneously toward one and the same act. For, in both physical and mental movements alike, the limbs are engaged in such an action according to the intent and meaning of the spirit of the mover concerning a certain object. And all actions where this is not combined appear to a sensible observer, like those of a fool, or of a madman.
It is also to be noted that all the limbs in whatever action or doing it may be, must exercise only their own functions; adding no motion to resting limbs, and no resting to moving or paralyzed limbs: nor any semblance of life to dead or sleeping bodies that appear to be alive or waking. For an image that is not animated with such movement when needed is to be expressed in such an incidence; and the observer must necessarily imagine from the representation that the limbs are not obedient to the spirit of such an image and do not let themselves be controlled; and therefore a great rigidity and a very unsuitable pairing in such an image will be observed. Indeed, it shall appear (so that we explain it through an example) as if the image was full of faults; and akin to someone trying to walk, through one.
