It reminds me of the infant described in Paul Schilder's article on clinging and equilibrium (Paul Schilder, "The Relations between Clinging and Equilibrium,"International Journal of Psychoanalysis, vol. 'LO (1939), pp. 58-63). The infant can defy gravity by the strength of its grasp; the new-born can suspend itself by its grasp. Schilder's point is that while it clings to the mother, the infant sucks and this secures the infant's equilibrium. Sucking and clinging-a masterful suspension, we might say-constitute an equilibrium in the field of an infantile organization of space. Later, the infant's clinging works quite differently; it helps to attain and preserve an upright posture. This is an adult organization of space and mastery of gravity. The former is predominantly libidinal, the latter has more to do with the evolutionary denlands of postural independence. I am talking about establishing an equilibrium different both from that which is a fusion with the mother's body and that which is a conquest of gravity. There is activity and mastery in each of these two organizations of equilibrium in space. Now, the necessity for independence from the mother is obvious. So why would we have a further need: that of a respite from postural independence? It is not so much that we want not to be upright. And certainly, we do not invite passivity. What we need is respite from an entire system of seeing and space that is bound up with mastery and identity. To see differently, albeit for a moment, allows us to see anew."
