As the
number of units taken diminishes, the amount of variety and inexactness
of generalization increases, because individuality tells for more and
more. Could you take men by the thousand billion, you could generalize
about them as you do about atoms; could you take atoms singly, it may be
that you would find them as individual as your aunts and cousins. That
concisely is the minority belief, and my belief.
Now what is called the scientific method in the physical sciences rests
upon the ignoring of individualities; and like many mathematical
conventions, its great practical convenience is no proof whatever of its
final truth. Let me admit the enormous value, the wonder of its results
in mechanics, in all the physical sciences, in chemistry, even in
physiology,--but what is its value beyond that? Is the scientific method
of value in biology? The great advances made by Darwin and his school in
biology were not made, it must be remembered, by the scientific method,
as it is generally conceived, at all. His was historical research. He
conducted research into pre-documentary history.
