eeding, I shall have no hesitation in coming before you, and
pointing out any change in my opinion without finding the slightest
occasion to blush for so doing. So I say that we accept this view as
we accept any other, so long as it will help us, and we feel bound
to retain it only so long as it will serve our great purpose--the
improvement of Man's estate and the widening of his knowledge. The
moment this, or any other conception, ceases to be useful for these
purposes, away with it to the four winds; we care not what becomes of
it!

But to say truth, although it has been my business to attend closely
to the controversies roused by the publication of Mr. Darwin's book,
I think that not one of the enormous mass of objections and obstacles
which have been raised is of any very great value, except that
sterility case which I brought before you just now. All the rest are
misunderstandings of some sort, arising either from prejudice, or want
of knowledge, or still more from want of patience and care in reading
the work.

For you must recollect that it is not a book to be read with as much
ease as its pleasant style may lead you to imagine. You spin through it
as if it were a novel the first time you read it, and think you know
all about it; the second time you read it you think you know rather less
about it; and the third time, you are amazed to find how little you have
really apprehended its vast scope and objects. I can positively say that
I never take it up without finding in it some new view, or light,
or suggestion that I have not noticed before. That is the best
characteristic of a thorough and profound book; and I believe this
feature of the 'Origin of Species' explains why so many persons have
ventured to pass judgment and criticisms upon it which are by no means
worth the paper they are written on.

Before concluding these lectures there is one point to which I must
advert,--though, as Mr. Darwin has said nothing about man in his book,
it concerns myself rather than him;--for I have strongly maintained on
sundry occasions that if Mr. Darwin's views are sound, they apply
as much to man as to the lower mammals, seeing that it is perfectly
demonstrable that the structural differences which separate man from the
apes are not greater than those which separate some apes from others.
There cannot be the slightest doubt in the world that the argument which
applies to the improvement of the horse from an earlier stock, o
