In the present volume I have endeavored to set before the reader the conception of a sequence of creative action commencing with the formation of the globe and culminating in a vista of infinite possibilities attainable by every one who follows up the right line for their unfoldment.<br />I have endeavored to show that, starting with certain incontrovertible scientific facts, all these things logically follow, and that therefore, however far these speculations may carry us beyond our past experience, they nowhere break the thread of an intelligible connection of cause and effect.<br />I do not, however, offer the suggestions here put forward in any other light than that of purely speculative reasoning; nevertheless, no advance in any direction can be made except by speculative reasoning going back to the first principles of things which we do know and thence deducing the conditions under which the same principles might be carried further and made to produce results hitherto unknown. It is to this method of thought that we owe all the advantages of civilization from matches and post-offices to motor-cars and aeroplanes, and we may therefore be encouraged to hope such speculations as the present may not be without their ultimate value.
