In addition to actual recollection, various other elements, more or less analogous to memory, enter into personality - habits, for instance, which have been formed as a result of past experience. It is because, where there is life, events can form habits, that an "experience" differs from a mere occurrence. An animal, and still more a man, is formed by experiences in a way that dead matter is not. If an event is causally related to another in that peculiar way that has to do with habit-formation, then the two events belong to the same "person." This is a wider definition than that by memory alone, including all that the memory-definition included and a good deal more.
