at the communication of thought is
conditioned upon this physical representation. If the logical series
comprises one thousand terms, each related to the preceding according to
logical law the physical series must comprise one thousand terms, each
physically related in such a manner as to reveal this law. As the
highest generalization comprises the fewest attributes, the concrete
expression of this idea will present the simplest possible physical form
and the least complexity of organization, and thus will present the
lowest types of life; and as the individual comprises the greatest
number of attributes, its concrete expression will present the greatest
complexity, and consequently the highest type of life. We have seen
that the logical process begins with the general and ends with the
individual; its material expression must therefore begin with the lowest
orders and end with the highest. But the individual cannot be
immediately derived from the general without the intervention of
intermediate generalizations. No more in the concrete expression of this
deduction can we pass from the lowest types to the highest without the
intervention of an intermediate series. These intermediate terms are not
capable of independent interpretation; they find their full explanation
only in the extremes of the series--God and Man.

If, then, in the intellectual process from the abstract and universal
towards the concrete and individual, we find a constant evolution of
idea, each advance being an addition to the previous conception, each
new term in the series embracing all the attributes of the preceding,
and differing only by addition; and if thought is possible only on this
condition; it necessarily follows that the material representation of
this thought must present physical forms similarly related, so that,
leaving out of view the intellectual genesis of this relation, the
observer might conclude that these forms compose a series evolved from a
primordial cell in accordance with an organic law. But such we find to
be the universal law of intellectual procedure: this apparent
development or evolution must, therefore, be the condition of the
communication of such intellectual process, and the physical terms are
brought into this relation by the fact that they symbolize the logical
process. If the material symbols of thought were unrelated physically,
the thoughts thus expressed would also be unrelated and independent. But
such a supp
