Memory is like the wind—no one knows where it comes fom or where it goes to when it is away. A witty man once suggested that it must be situated in the back of the head, becuase whenever anyone struggled to remember a particular date or event, he usually scratched there.

Memory as a storehouse of enriching thoughts, memory as an aid to success, memory as a cause of pain through misuse, self-conscious memory as a dinvine act of creation, are but a few fascinating phases of memory which Professor Phelps treats of in his enlivening volume.

William Lyon Phelps was a Lampson Professor of English Literature at Yale University, and author of Happiness, Love, etc.
