“Morphic fields, like the known fields of physics, are non-material regions of influence extending in space and continuing in time. They are localized within and around the systems they organize. When any particular organized system ceases to exist — as when an atom splits, a snowflake melts, an animal dies — its organizing field disappears from that place. But in another sense, morphic fields do not disappear: they are potential organizing patterns of influence, and can appear again physically in other times and places, wherever and whenever the physical conditions are appropriate. When they do so they contain within themselves a memory of their previous physical existences.”
