ut to accept it tentatively and to
examine carefully what conclusions it may seem to carry with it--how it
may affect our outlook upon the world as a whole.

45. THE PLACE OF MIND IN NATURE.--One of the very first questions which
we think of asking when we contemplate the possibility that the physical
world is throughout a mechanical system is this: How can we conceive
minds to be related to such a system? That minds, and many minds, do
exist, it is not reasonable to doubt. What shall we do with them?

One must not misunderstand the mechanical view of things. When we use
the word "machine," we call before our minds certain gross and relatively
simple mechanisms constructed by man. Between such and a flower, a
butterfly, and a human body, the difference is enormous. He who elects
to bring the latter under the title of mechanism cannot mean that he
discerns no difference between them and a steam engine or a printing
press. He can only mean that he believes he might, could he attain to a
glimpse into their infinite complexity, find an explanation of the
physical changes which take place in them, by a reference to certain
general laws which describe the behavior of material particles everywhere.

And the man who, having extended his notion of mechanism, is inclined to
overlook the fact that animals and men have minds, that thought and
feeling, plan and purpose, have their place in the world, may justly be
accused of a headlong and heedless enthusiasm. Whatever may be our
opinion on the subject of the mechanism of nature, we have no right to
minimize the significance of thought and feeling and will. Between that
which has no mind and that which has a mind there is a difference which
cannot be obliterated by bringing both under the concept of mechanism.
It is a difference which furnishes the material for the sciences of
psychology and ethics, and gives rise to a whole world of distinctions
which find no place in the realm of the merely physical.

There are, then, minds as well as bodies; what place shall we assign to
these minds in the system of nature?

Several centuries ago it occurred to the man of science that the material
world should be regarded as a system in which there is constant
transformation, but in which nothing is created. This way of looking at
things expressed itself formerly in the statement that, through all the
changes that take place in the world, the quantity of matter and motion
remains the
