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. 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.

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.

Relying on the maxim that Principle is not bound by Precedent we should not limit our expectations of the future; and if our speculations lead us to the conclusion that we have reached a point where we are not only able, but also required, by the law of our own being, to take a more active part in our personal evolution than heretofore, this discovery will afford us a new outlook upon life and widen our horizon with fresh interests and brightening hopes. If the thoughts here suggested should help any reader to clear some mental obstacles from his path the writer will feel that he has not written to no purpose.

Only each reader must think out these suggestions for himself. No writer or lecturer can convey an idea into the minds of his audience. He can only put it before them, and what they will make of it depends entirely upon themselves--assimilation is a process which no one can carry out for us. To the kindness of my readers on both sides of the Atlantic, and in Australia and New Zealand, I commend this little volume, not, indeed, without a deep sense of its many shortcomings, but at the same time encouraged by the generous indulgence extended to my previous books.
