It is not often that the author of a work on
science or philosophy so far accepts the verdict of his critics as to
entirely re-model and re-write his book. Much to his credit Prof. Calderwood
has done this, for the second edition now just issued is not only nearly
twice the bulk of the first, but is also full of new matter, and is greatly
improved in its scope and arrangement. The first edition (reviewed in
Nature, vol. xlvii. p. 385) contained eight chapters, while the
present work has seventeen, the titles and "contents" of which are so
different that the two books seem to have little in common. The chapters
on "The Nerve System as an Instrument of Knowledge," "Right and Wrong,"
"Civil Law," "Modern Thought," "The Ape and Man," and "Cosmic Problems,"
seem to be wholly new and to embody the results of the most recent researches.
In other respects the present work is far superior to the former edition,
as it not only gives a much larger body of facts, and contains less repetition,
but is a more complete presentation of the whole subject, treated from
the point of view of philosophy rather than from that of science.
The author's style, which leads him always to
go round about a subject rather than to the heart of the problem itself,
to take much for granted which requires systematic proof, and to revel
in diffuseness of phraseology and of argument, is still a prominent feature,
and is wearisome to the reader who wants to get at the author's conclusions
and to have a clear presentation of the facts and arguments on which they
are founded. But to those who enjoy diffuse philosophical discussion,
and especially to those who want a reply to the supposed materialistic
tendencies of the works of Darwin and Herbert Spencer, there is here much
food for thought. A few passages will serve to illustrate the author's
merits as well as his limitations. In the chapter on "Right and Wrong,"
he thus explains his view of the essential difference between the human
and the animal nature.
"The grand distinction of human
life is self-control in the field of action. Thought not only
reaches a generalised knowledge of existence, and of its laws; it leads
to rationalised action, within the many and varied fields of human endeavour.
The evidence of this appears, as already described, in the control exercised
over all the animal impulses, so that these do not spontaneously and
of themselves determine activity. Sensibility operates in human life,
just as in the life of the animal; but it does not at once direct our
action, as the course of the dog is ruled by sense of smell. Sensibility
can influence us in the same way, and a similar result is often seen
in our life; but that which is peculiar to man is a concentration which
overcomes allurements of sense. Animal appetite is stirred in us, as
in animals, physiological law being coextensive with the animal kingdom;
our speciality appears in the regulation of animal impulse, so that
it is repressed, in accordance with the laws of attention, which weaken
or strengthen animal propensity; or limited by reference to propriety;
or regulated in its indulgence in recognition of a law higher than present
desire. These facts are so familiar, that I have only to refer to them
to claim their weight of evidence for a power which does not appear
in animal life. The value of this evidence will be still more appreciated,
if it be observed that the control of animal impulse no more belongs
to the animal nature of man, than it belongs to the animals around him.
In respect of animal impulse, his experience is as much determined by
physiological law, as animals are visibly moved by it. Man being an
animal, no one can suggest that the movements of animal impulse are
otherwise determined or have their source elsewhere than in the body.
The difference between man and animals appears in this, that by thought
and imagination passion may be intensified; and by use of these powers
it can be restrained. Even within the sphere of passion, the elevation
of human life is seen in the control the rational power wields over
the animal nature."
The purport of this wordy and laboured passage
is clear enough, but its cogency as an argument is certainly not proportioned
to its length. The same idea is pursued through two other paragraphs of
equal length, but these do not bring any further sense of completeness
to the presentation of the subject.
One more extract may be given from the final
chapter on "Cosmic Problems."
"With clearest testimony, scientific
observation has led us to innumerable points, whence we have seen intelligent
purpose at work providing for life yet unborn. We have been arrested first,
and afterwards roused to quickened consciousness, realising that we have
seen the lesson all the days of our life, in hundreds of forms, but had
not read its full meaning, though it had been written large; for is not
the whole vegetable kingdom confessedly a preparation for a coming life?
In vain does Agnosticism lift its voice in presence of witness such as
this. Testimony for an Intelligent cause springs even from the dust,
and, as it comes thence, thought moves freely along all fields of science,
gathering evidence as readily from the vegetable kingdom as from the animal;
finding, with ever-increasing surprise, a growing testimony as science
conducts us lower in the knowledge of nature. Not to the heights but to
the depths we go, in order to witness the most startling condemnation
of Agnosticism. It is not merely the myriad dwellers in the insect world
which bear witness; but the inanimate creation itself tells us of treasure
stored in its keeping, to satisfy animal wants. Plants can manufacture
fresh protoplasm out of mineral compounds, whereas animals are obliged
to procure it ready made, and hence in the long run depend upon plants.
Thus, even from the soil, under our feet, comes the evidence
calling us to own an Intelligent First Cause."
A number of illustrations, of the lower forms
of life, of the sense organs of various classes of animals, and of the
brains of many of the mammalia and of man, will render the work more attractive
to those who have not acquired a general knowledge of the subject from
A. R. W.
