And here I would forestall the Reader's objection that the feeling of effort and resistance, essential to all our empathic dealings with two-dimensional shapes, must, after all, be due to _weight,_ which we have just described as a quality shapes cannot possess. My answer is that Empathy has extracted and schematised effort and resistance by the elimination of the thought of weight, as by the elimination of the awareness of our bodily tensions; and that it is just this elimination of all incompatible qualities which allows us to attribute activities to those two-dimensional shapes, and to feel these activities, with a vividness undiminished by the thought of any other circumstances. With cubic existence (and its correlative three-dimensional space), with weight and texture we have therefore got from the contemplated shape to a thought alien to that shape and its contemplation. The thought, to which life and its needs and dangers has given precedence over every other: What _Thing_ is behind this shape, what qualities must be inferred from this _aspect?_ After the possibility of occupying so much space, the most important quality which things can have for our hopes and fears, is _the possibility of altering their occupation of space;_ not our locomotion, but _theirs._ I call it _locomotion_ rather than _movement,_ because we have _direct_ experience only of our own movements, and _infer_ similar movement in other beings and objects because of their change of place either across our motionless eye or across some other object whose relation to our motionless eye remains unchanged. I call it _locomotion_ also to accentuate its difference from the _movement_ attributed to the shape of the Rising Mountain, movement _felt_ by us to be going on but not expected to result in any change of the mountain's space relations, which are precisely what would be altered by the mountain's _locomotion._
