ne step farther, and boldly
assert that the existence of God is, on this hypothesis, incapable of
proof, and the only logical position Dr. Warren can occupy is that of
spiritualistic Pantheism.

Dr. Warren asserts that "the Dynamical theory of matter" is now
generally accepted by "Anglo-Saxon _naturalists_." "One can scarcely
open a scientific treatise without observing the altered stand-point"
(p. 160). We confess that we are disappointed with Dr. Warren's
treatment of this simple question of fact. On so fundamental an issue,
the Doctor ought to have given the name of at least _one_ "naturalist"
who asserts that "the ultimate atoms of matter are as uniformly
efficient as minds." Leibnitz, Morrell, Ulrici, Hickok, the authorities
quoted by him, are metaphysicians and idealists of the extremest school.
At present we shall, therefore, content ourselves with a general denial
of this wholesale statement of Dr. Warren; and we shall sustain that
denial by a selection from the many authorities we shall hereafter
present. "No particle of matter possesses within itself the power of
changing its existing state of motion or of rest. Matter has no
spontaneous power either of rest or motion, but is equally susceptible
to each as it may be acted on by _external_ causes" (Silliman's
"Principles of Physics," p. 13). The above proposition is "a truth on
which the whole science of mechanical philosophy ultimately depends"
(Encyclopaedia Britannica, art. "Dynamics," vol. viii. p. 326). "A
material substance existing alone in the universe could not produce any
effects. There is not, so far as we know, a self-acting material
substance in the universe" (M'Cosh, "Divine Government, Physical and
Moral," p. 78). "Perhaps the only true indication of matter is
_inertia_." "The cause of gravitation is _not resident_ in the particles
of matter merely," but also "_in all space_" (Dr. Faraday on
"Conservation of Force," in "Correlation and Conservation of Force." (p.
368). He also quotes with approbation the words of Newton, "That gravity
should be innate, inherent, and essential to matter, is so great an
absurdity, that I believe no man who has in philosophic matters a
competent faculty of thinking can ever fall into it" p. 368). "The
'force of gravity' is an improper expression" (p. 340). "Forces are
transformable, indestructible, and, _in contradistinction from matter_,
imponderable" (p. 346). "The first cause of things is Deity" (Dr. Mayer,
in "
