PREFACE

What I here make public has, after a long and scrupulous inquiry, seemed
to me evidently true and not unuseful to be known--particularly to those
who are tainted with Scepticism, or want a demonstration of the existence
and immateriality of God, or the natural immortality of the soul. Whether
it be so or no I am content the reader should impartially examine; since
I do not think myself any farther concerned for the success of what I
have written than as it is agreeable to truth. But, to the end this may
not suffer, I make it my request that the reader suspend his judgment
till he has once at least read the whole through with that degree of
attention and thought which the subject-matter shall seem to deserve.
For, as there are some passages that, taken by themselves, are very
liable (nor could it be remedied) to gross misinterpretation, and to be
charged with most absurd consequences, which, nevertheless, upon an
entire perusal will appear not to follow from them; so likewise, though
the whole should be read over, yet, if this be done transiently, it is
very probable my sense may be mistaken; but to a thinking reader, I
flatter myself it will be throughout clear and obvious. As for the
characters of novelty and singularity which some of the following notions
may seem to bear, it is, I hope, needless to make any apology on that
account. He must surely be either very weak, or very little acquainted
with the sciences, who shall reject a truth that is capable of
demonstration, for no other reason but because it is newly known, and
contrary to the prejudices of mankind. Thus much I thought fit to
premise, in order to prevent, if possible, the hasty censures of a sort
of men who are too apt to condemn an opinion before they rightly
comprehend it.

INTRODUCTION

1. Philosophy being nothing else but THE STUDY OF WISDOM AND TRUTH, it
may with reason be expected that those who have spent most time and pains
in it should enjoy a greater calm and serenity of mind, a greater
clearness and evidence of knowledge, and be less disturbed with doubts
and difficulties than other men. Yet so it is, we see the illiterate bulk
of mankind that walk the high-road of plain common sense, and are
governed by the dictates of nature, for the most part easy and
undisturbed
