hat the dull vital actions
of a fungus, or a foraminifer, are the properties of their protoplasm,
and are the direct results of the nature of the matter of which they are
composed. But if, as I have endeavoured to prove to you, their
protoplasm is essentially identical with, and most readily converted
into, that of any animal, I can discover no logical halting-place
between the admission that such is the case, and the further concession
that all vital action may, with equal propriety, be said to be the
result of the molecular forces of the protoplasm which displays it. And
if so, it must be true, in the same sense and to the same extent, that
the thoughts to which I am now giving utterance, and your thoughts
regarding them, are the expression of molecular changes in that matter
of life which is the source of our other vital phaenomena.

Past experience leads me to be tolerably certain that, when the
propositions I have just placed before you are accessible to public
comment and criticism, they will be condemned by many zealous persons,
and perhaps by some few of the wise and thoughtful. I should not wonder
if "gross and brutal materialism" were the mildest phrase applied to
them in certain quarters. And, most undoubtedly, the terms of the
propositions are distinctly materialistic. Nevertheless two things are
certain; the one, that I hold the statements to be substantially true;
the other, that I, individually, am no materialist, but, on the
contrary, believe materialism to involve grave philosophical error.

This union of materialistic terminology with the repudiation of
materialistic philosophy I share with some of the most thoughtful men
with whom I am acquainted. And, when I first undertook to deliver the
present discourse, it appeared to me to be a fitting opportunity to
explain how such a union is not only consistent with, but necessitated
by, sound logic. I purposed to lead you through the territory of vital
phaenomena to the materialistic slough in which you find yourselves now
plunged, and then to point out to you the sole path by which, in my
judgment, extrication is possible.

An occurrence of which I was unaware until my arrival here last night
renders this line of argument singularly opportune. I found in your
papers the eloquent address "On the Limits of Philosophical Inquiry,"
which a distinguished prelate of the English Church delivered before the
members of the Philosophical Institution on the previous
