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.
