It will seem to the average reader easier to accept the fact of Immortality than try to understand Mr. Dunne by following his explanations. He takes us through practically every known field of science, music, mathematics, physics and philosophy. Briefly he makes two statements:- (1) that by mistaking the hybrid for real time we come inevitably to the conclusion everything is transient; (2) whereas in real time everything that has established its existence exists forever. This is not a religious book (although some clergymen will find its arguments extremely helpful in combating scientists)
