The pneumatic assimilator has the transcendental capacity to for accretions of pneuma. What the accretions are is not restricted. We do however face the potential issue of a situation in which the phantasy of spatio temporality as created by the assimilator is a ground layer as given also transcendentally or the converse of transcendental realism. Either way there is a ground posited on which the accretions form. It suggests a kind of way in which the pneuma is thin in some regions until our attention is brought to bear. This is no the thinness of the ready to hand, which is certainly a kind of accretion, though it is presentness to hand which forms durable accretive structures that have the characteristic of reification -the formation of a strong accretion.
