nus_ has been reached. The truths communicated in the symbols of
Nature, have been correlated and enunciated, and finally translated from
the dialect of man the physical into the language of man the
intellectual. Physical science determines the separate words of this
message of God, the letters of which are scattered throughout Nature.
Metaphysics combines these words into propositions which enunciate a
distinct truth. There is therefore neither conflict nor variation
between the method of Logic and the method of Nature. The movement of
both is in the same direction; the only difference is in the point of
starting. And another truth no less important, which follows from the
foregoing discussion, is that the method of Nature is fundamental to the
method of Logic. Physics should precede metaphysics, but not exclude it;
both are essential to every true science, and physics, which stops with
physics, leads man by dazzling promises into some Utopian desert only to
leave him there to die of hunger. And it is no less true that
metaphysics, without this basis in experimental science, is illusory
and untrustworthy, wherever the original data are necessarily empirical.

Two conditions are thus necessary to all science: a body of knowable
truth capable of being systematized; and an intelligence capable of
apprehending and systematizing it. One of these conditions is physical
and one is metaphysical; and all true science must be the resultant of
Law and Idea, the Objective and the Subjective, the twin forces of
Nature and Man. If either of these conditions be wanting, there can be
no true science, for science can neither be "evolved from the depths of
the personal consciousness," nor can the scattered letters of scientific
truth, as given in nature, arrange themselves into the words of a
significant message. Knowledge must be classified before it is science,
and that which classifies can only be intellect--discovering and
enunciating this classification according to the laws of mental action.
As prominence is given to one or other of these two conditions we have
the division into Logical and Natural, but the fundamental principle of
classification is the same in both--it being simply the law of
intellectual action--just as the law which governs the action of the
levers of a loom will determine the pattern of the woven fabric. There
can, therefore, be no conflict between the methods of Logic and those of
Nature. The determining eleme
