“One's present personality cannot share all the thoughts of one's older personalities — and yet it has some sense that they exist. This is one reason why we feel that we possess an inner Self — a sort of ever-present person-friend, inside the mind, whom we can always ask for help.”
The Society of Mind (1987)

This I Believe (1951)
Context: This I Believe — by that name, we present the personal philosophies of thoughtful men and women in all walks of life.
