On the other hand, our investigations may be more profound, and we may
scrutinize the very foundations upon which a science rests. Both the
other works referred to illustrate this method of procedure.

For example, in "The Grammar of Science," we find our author
discussing, under the title "The Facts of Science," such problems as
the following: the Reality of Things; Sense-impressions and
Consciousness; the Nature of Thought; the External Universe; Sensations
as the Ultimate Source of the Materials of Knowledge; and the Futility
of "Things-in-themselves." The philosophical character of such
discussions does not need to be pointed out at length.
