The influence of previous structures on subsequent similar structures of activity organized by morphic fields. According to the hypothesis of formative causation, morphic resonance involves the transmission of formative influences through or across time and space without a decrease due to distance or lapse of time.

The influence of previous structures of activity on subsequent similar structures of activity organized by morphic fields. Through morphic resonance, formative causal influences pass through or across both space and time, and these influences are assumed not to fall off with distance in space or time, but they come only from the past. The greater the degree of similarity, the greater the influence of morphic resonance. in general, morphic units closely resemble themselves in the past and are subject to self-resonance from their own past states.
