n, very far
removed from Haeckel's certainty and orthodoxy.

To sum up: O. Hertwig has become a serious heretic in matters
Darwinian. Will Haeckel, in his usual manner try to cast suspicion on
Hertwig also? For Haeckel himself says (Free Science and Free Doctrine,
Stuttgart, 1878, p. 85): "Since I am not bound by fear to the Berlin
Tribunal of Science or by anxieties regarding the loss of influential
Berlin connections, as are most of my like-minded colleagues, I do not
hesitate here as elsewhere to express my honest conviction, frankly and
freely, regardless of the anger which perhaps real or pretended privy
councillors in Berlin may feel upon hearing the unadorned truth."

Verily, it is a matter of suspense to know whether his school will now
pour forth their wrath upon O. Hertwig, or whether finally the
discovery will not be made in Jena that Hertwig secretly possessed
himself of his position in Berlin, in the same manner as Fleischmann
obtained his at Erlangen, viz., by a promise of desertion from
Darwinism.

CONCLUSION.

We may conveniently summarize what we have said in the foregoing
chapters in the following statement: The theory of Descent is almost
universally recognized to-day by naturalists as a working hypothesis.
Still, in spite of assertions to the contrary, no conclusive proof of
it has as yet been forthcoming. Nevertheless it cannot be denied that
the theory provides us with an intelligible explanation of a series of
problems and facts which cannot be so well explained on other grounds.

On the other hand, Darwinism, i.e., the theory of Natural Selection by
means of the Struggle for Existence, is being pushed to the wall all
along the line. The bulk of naturalists no longer recognizes its
validity, and even those who have not yet entirely discarded it, are at
least forced to admit that the Darwinian explanation now possesses a
very subordinate significance.

In the place of Darwinian principles, new ideas are gradually winning
general acceptance, which, while they are in harmony with the
principles of adaptation and use, (Lamarck) enunciated before the time
of Darwin, nevertheless attribute a far-reaching importance to _internal
forces of development_. These new conceptions necessarily involve
the admission that _Evolution has not been a purely mechanical
process_.
