" He continues:--
"Many phenomena only appear to be intelligible if we assume the
hereditary transmission of such acquired characters as the changes
which we ascribe to the use or disuse of particular organs, or to
the direct influence of climate. Furthermore, how can we explain
instinct as hereditary habit, unless it has gradually arisen by the
accumulation, through heredity, of habits which were practised in
succeeding generations?" {277}
I may say in passing that Professor Weismann appears to suppose that
the view of instinct just given is part of the Charles-Darwinian
system, for on page 389 of his book he says "that many observers had
followed Darwin in explaining them [instincts] as inherited habits."
This was not Mr. Darwin's own view of the matter. He wrote:--
"If we suppose any habitual action to become inherited--and I think
it can be shown that this does sometimes happen--then the
resemblance between what originally was a habit and an instinct
becomes so close as not to be distinguished.
