It is apparent that the body is not immortal; it has an obvious beginning and an obvious end. What we expect to be immortal in man is thus invisible, is spirit, a mysterious presence that animates body with consciousness. Each of us knows this presence very well, for it is what we feel ourselves to be; it is what we refer to when we say “I.” This “I” then, this consciousness we know to be ourselves, is what we expect to be perpetuated after the death of the body.
