ther, on the
ground that it has neither the implements nor the capacities with which to
investigate in that realm. This proves as conclusively as anything could
that the distinction between these two realms is so sharp, as well as so
self-evident, that science is compelled to accept it and act accordingly.

2. The =Faculties of Investigation= Must be Distinguished.

The scientific man will next distinguish the faculties with which the
investigating is to be done, according to the respective realms. That this
classification is required by the fundamental difference in the nature of
the truths in these two realms is so self-evident that it ought to be
axiomatic to all who think with any degree of scientific accuracy. For in
the nature of things, =natural= truth requires investigation by
=intellectual= faculties, and =spiritual= truth by =spiritual= faculties.
Indeed, this distinction is fully recognized when science halts its pursuit
of truth at the boundary line of the spiritual realm.

Yet, although this classification is theoretically recognized by science,
and although it is absolutely demanded if we are to proceed scientifically
in our researches in the spiritual realm, it is little less than amazing
how many there are who utterly fail to distinguish these faculties when
they start out to investigate spiritual truth. Indeed, this is the first
place where the Church and the Schools part company. For the whole attitude
of our Schools today, including most of the institutions founded and
fostered by the Church, seems to be one that entirely misses the scientific
necessity of distinguishing between these essentially different faculties
when working in these two utterly divergent realms of truth. And so it
comes to pass that while the Church is using one sort of faculties, the
Schools are using another kind on the same class of truth.

It needs scarcely to be argued that the =intellect=, with its capacity to
=reason=, is the proper faculty of apprehension in the scientific realm.
But it is equally true that the =heart=, with its capacity to =believe=, is
the one faculty of apprehension in the spiritual realm. That is, the
inquirer reasons his way to knowledge in the natural realm, and believes
his way to knowledge in the spiritual realm. He uses his mind in order to
understand what God has done in His creation, and he exercises faith in
order to come into the knowledge of what He is in His character. In natural
things h
