y true. It does not, however, contain the
_whole truth_ in relation to the subject of investigation. It is just as
correct to say that the progress of mankind depends on the success with
which the moral or religious faculties--faculties which instigate
devotion to our highest perception of right--are cultivated, and on the
extent to which they are practically active. For it is not in the
inculcation of intellectual truth alone, or preeminently, nor in the
cultivation of moral strength alone, or predominantly, that the progress
of mankind is secured; but in the developing vigor of _both_ mental and
moral forces, and in their mutual cooeperation and assistance.

The proposition, as announced by Mr. Buckle, is, therefore, either a
half-truth, which does not sufficiently explain the cause of 'the
progress of mankind,' which the Historian avers that it unfolds, or it
is actually false, accordingly as it is understood to state a verity
which does not exclude the _affirmative_ statement of an opposite and
apparently antagonistic truth, or as it is interpreted to be the
explanation of the whole or main cause upon which the advancement of
society has depended. That the author of 'Civilization in England'
regarded it in this latter light, is plainly apparent. His whole work is
an elaborate attempt to establish the invalid theory, that human
progress is due _almost exclusively_ to the enlightenment of the
intellect, and in a very minor degree only to the cultivation of the
moral or religious nature. In a certain sense it is indeed true that
_all_ social elevation is the result of intellectual growth; but it is
only in that _absolute_ sense in which the Intellect is used for the
totality of human faculties, and of course includes the moral faculty
itself. In this sense, it is just as true to say that all progress is
through the Moral Powers, using this term to include the whole of the
human Mind, and consequently the intellectual forces. In either case,
the question still remains, of the relative effect of the Intellectual
and Moral powers upon the career of humanity, when considered as not
including each other. It was in this _relative_ point of view that Mr.
Buckle entertained it.

With this cursory examination of the first and second propositions,
their distinctive consideration will close. Some things, however, that
will have to be enunciated in the investigation of the English
Historian's Generalizations as a whole, are also
