But philosophers have not always been clear in stating just which type of memory is necessary for personal identity, and this makes the task a bit more involved. There are, actually, several known types. The memory required by personal identity must be retained over the span of a lifetime. Hence Lockean memory is long-term. Long-term memories can be either implicit or explicit.
Explicit memories have truth value, and can be proved true or false.
When we recall an experience from life, our recall may be accurate or not. By comparing our recall with factual history we can determine the memory's truthfulness. Memories of facts are unrelated to one another. The two factual memories are disconnected, separate. In future I will associate the two prior images, those of a deer and a stripped tree, together in this novel event.
