acknowledgment the greatest number of truths have been ascertained and
the greatest possible degree of certainty arrived at?"

We learn from Mill himself that he made an attempt about this
time, while his mind was full of Herschel's Discourse, to connect a
scientific method with the body of the Old Logic. But he could not
make the junction to his satisfaction, and abandoned the attempt in
despair. A little later, in 1837, upon the appearance of Whewell's
_History of the Inductive Sciences_, he renewed it, and this time with
happier results. Whewell's _Philosophy of the Inductive Sciences_
was published in 1840, but by that time Mill's system was definitely
shaped.

It was, then, to Herschel and Whewell, but especially to the former,
that Mill owed the raw materials of his Inductive Method. But why did
he desire to concatenate this with the old Logic? Probably because he
considered that this also had its uses for the student of society, the
political thinker. He had inherited a respect for the old Logic from
his father. But it was the point at which he sought to connect the
new material with the old, the point of junction between the two, that
determined the form of his system. We find the explanation of this in
the history of the old Logic. It so happened that Whately's Logic was
in the ascendant, and Whately's treatment of Induction gives the key
to Mill's.

Towards the end of the first quarter of this century there was a
great revival of the study of Logic at Oxford. The study had become
mechanical, Aldrich's Compendium, an intelligent but exceedingly brief
abstract of the Scholastic Logic, being the text-book beyond which
no tutor cared to go. The man who seems to have given new life to the
study was a tutor who subsequently became Bishop of Llandaff, Edward
Copleston. The first public fruits of the revival begun by him was
Whately's article on Logic in the _Encyclopaedia Metropolitana_,
published as a separate book in 1827. Curiously enough, one of
Whately's most active collaborators in the work was John Henry Newman,
so that the common room of Oriel, which Mr. Froude describes as the
centre from which emanated the High Church Movement, may also be
said to have been the centre from which emanated the movement that
culminated in the revolution of Logic.

The publication of Whately's Logic made a great stir. It was reviewed
by Mill, then a young man of twenty-one, in the _Westminster Review_
(1828), and by Hamilt
