Full Idea
On Whitehead's view, not only is a volitional sense of 'causal power' projected on to physical events, but 'perception in the causal mode' is literally ascribed to them.
Gist of Idea
Whitehead held that perception was a necessary feature of all causation

A Reaction
This seems to be a close relative of Leibniz's monads. 'Perception' is a daft word for it, but in some way everything is 'responsive' to the things adjacent to it.
