Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The human race has reflected so long and often on these prob lems that the same patterns of thought recur in almost every age. We should know what these thoughts are. We should know what answers have been suggested by those who have most influenced ancient and modern thought. We shall want to do our own thinking and find our own answers. It is, however, neither necessary nor advisable to travel alone. Others have helped dispel the darkness, and the light they have kindled may also illumine our way.
