DEAR READER:Perhaps this is your story as well as John Lemaire's. It tries to show the effect, upon one growing mind, of the profound transformation which modern science and research have brought in the faith of the western world. In a lesser way it tries also to show the political experiments and disillusionment of our time, and to trace the evolution of a fairly typical rebel from Utopian aspiration through a cynical despondency to some measure of reconciliation and good cheer.These changes have not been as impersonal as the abstract chronicle of history represents them; they have brought to sensitive individuals much suffering in mental transition and readjustment; they have broken up families and friendships; and they have unsettled the mind and morals of many generations by uprooting the customs and beliefs in which those generations grew. It is with this personal aspect of the Great Change that this story is concerned.
