PREFACE TO THE FIRST EDITION.

This book makes no pretense of giving to the world a new theory of the
intellectual operations. Its claim to attention, if it possess any, is
grounded on the fact that it is an attempt, not to supersede, but to
embody and systematize, the best ideas which have been either promulgated
on its subject by speculative writers, or conformed to by accurate
thinkers in their scientific inquiries.

To cement together the detached fragments of a subject, never yet treated
as a whole; to harmonize the true portions of discordant theories, by
supplying the links of thought necessary to connect them, and by
disentangling them from the errors with which they are always more or less
interwoven, must necessarily require a considerable amount of original
speculation. To other originality than this, the present work lays no
claim. In the existing state of the cultivation of the sciences, there
would be a very strong presumption against any one who should imagine that
he had effected a revolution in the theory of the investigation of truth,
or added any fundamentally new process to the practice of it. The
improvement which remains to be effected in the methods of philosophizing
(and the author believes that they have much need of improvement) can only
consist in performing more systematically and accurately operations with
which, at least in their elementary form, the human intellect, in some one
or other of its employments, is already familiar.

In the portion of the work which treats of Ratiocination, the author has
not deemed it necessary to enter into technical details which may be
obtained in so perfect a shape from the existing treatises on what is
termed the Logic of the Schools. In the contempt entertained by many
modern philosophers for the syllogistic art, it will be seen that he by no
means participates; though the scientific theory on which its defense is
usually rested appears to him erroneous: and the view which he has
suggested of the nature
