PREFACE TO THE SECOND EDITION.

The author's aim has been to produce such a condensation of the original
work as may recall its contents to those who have read it, and may serve
those who are now reading it in the place of a full body of marginal
notes. Mr. Mill's conclusions on the true province and method of Logic
have a high substantive value, independent even of the arguments and
illustrations by which they are supported; and these conclusions may be
adequately, and, it is believed, with much practical utility, embodied
in an epitome. The processes of reasoning on which they depend, can, on
the other hand, be represented in outline only. But it is hoped that the
substance of every paragraph, necessary for the due comprehension of the
several steps by which the results have been reached, will be here
found at all events suggested.

The author may be allowed to add, that Mr. Mill, before publication,
expressed a favourable opinion of the manner in which the work had been
executed. Without such commendation the volume would hardly have been
offered to the public.
