Full Idea
I accept the reciprocity of interactions, and abandon the Agent vs.Patient distinction, so we can no longer talk of the contribution of each as ontologically different types of cause. In interactions, neither action nor reaction can be separated.
Clarification
Agent and Patient are active and passive particants
Gist of Idea
Causal events are always reciprocal, and there is no distinction of action and reaction

A Reaction
His point is that we are misled by real world happenings, where one component is usually more powerful than the other (such as ball dropped onto a pillow). Modern science endorses his view. Mumford and Anjum seem to agree, and so do I.
