(Gk., mnēmē, memory) The causal relation existing between an earlier event and a subsequent episode of remembering it. The term was used by Russell but is not current, because there may be such a relation without the causation being of a special type, for instance if we suppose the memory to be carried by traces in the brain. The relation between the content of the memory and the early event is what is so special.
