Abstract I.F. Clarke brings the present series to a temporary and appropriate end with an invitation to boldly go where many have gone before. As he points out, the space journey has been one of the most popular themes in future fiction, since it presents the utmost reach of the imagination and the most striking achievements of technology. Behind these numerous tales of human endeavour and adventure, however, he finds ancient archetypes at work. The voyage out is an escape from old Terra and its many problems. There is a better world for the finding far away in distant galaxies. Humankind will go on for ever and ever. In marked contrast to Pascal's anxieties, the eternal silence of infinite space has no terrors in these voyages of the imagination.
