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.
