An Appeal To Reason
Concluding these statements, let us say that the student of this book
will find nothing contained within this book which is contrary to
Nature's laws and principles. He will nowhere in it be asked to suspend
the exercise of his reason, and to accept as facts things which violate
all of Nature's laws. Instead, he will find at each point full natural
explanations of even the most wonderful phenomena; and the appeal to
accept same will be made always to his reason, and not to his blind
faith or unreasoning belief. The student is urged to build his knowledge
of this important subject upon this solid rock of natural law and fact,
and not upon the shifting and sinking sands of mere dogmatic assertion
and appeal to assumed authority ancient or modern.
