ABSTRACT
“The notion of interaction is not simple but very complex. The notion involves not simply the idea of bare collision and rebound, but something much more profound, namely, the internal modifiability of the colliding agents&. The situation is not thinkable at all if we do not suppose the internal modifiability of the agents, and this means that these agents are able somehow to receive internally and to react upon impulses which are communicated externally in the form of motion or activity. The simplest form of interaction involves the supposition, therefore, of internal subject-points of their analogues from which impulsions are received and responded to.”—ALEXANDER T. ORMOND in Foundations of Knowledge.
