closely to my plan, and should 
probably have been furnished by him with much that would have 
enriched the book and made it more worthy of his acceptance; but this 
was not to be. 
In the course of writing I became more and more convinced that no 
progress could be made towards a sounder view of the theory of 
descent until people came to understand what the late Mr. Charles 
Darwin's theory of natural selection amounted to, and how it was that it 
ever came to be propounded. Until the mindless theory of Charles 
Darwinian natural selection was finally discredited, and a mindful 
theory of evolution was substituted in its place, neither Mr. Tylor's 
experiments nor my own theories could stand much chance of being 
attended to. I therefore devoted myself mainly, as I had done in 
"Evolution Old and New," and in "Unconscious Memory," to 
considering whether the view taken by the late Mr. Darwin, or the one 
put forward by his three most illustrious predecessors, should most 
command our assent. 
The deflection from my original purpose was increased by the 
appearance, about a year ago, of Mr. Grant Allen's "Charles Darwin," 
which I imagine to have had a very large circulation. So important, 
indeed, did I think it not to leave Mr. Allen's statements unchallenged, 
that in November last I recast my book completely, cutting out much 
that I had written, and practically starting anew. How far Mr. Tylor 
would have liked it, or even sanctioned its being dedicated to him, if he 
were now living, I cannot, of course, say. I never heard him speak of 
the late Mr. Darwin in any but terms of warm respect, and am by no 
means sure that he would have been well pleased at an attempt to 
connect him with a book so polemical as the present. On the other hand, 
a promise made and received as mine was, cannot be set aside lightly. 
The understanding was that my next book was to be dedicated to Mr. 
Tylor; I have written the best I could, and indeed never took so much
pains with any other; to Mr. Tylor's memory, therefore, I have most 
respectfully, and regretfully, inscribed it. 
Desiring that the responsibility for what has been done should rest with 
me, I have avoided saying anything about the book while it was in 
progress to any of Mr Tylor's family or representatives. They know 
nothing, therefore, of its contents, and if they did, would probably feel 
with myself very uncertain how far it is right to use Mr. Tylor's name in 
connection with it. I can only trust that, on the whole, they may think I 
have done most rightly in adhering to the letter of my promise.

CHAPTER I--INTRODUCTION 
 
I shall perhaps best promote the acceptance of the two main points on 
which I have been insisting for some years past, I mean, the substantial 
identity between heredity and memory, and the reintroduction of design 
into organic development, by treating them as if they had something of 
that physical life with which they are so closely connected. Ideas are 
like plants and animals in this respect also, as in so many others, that 
they are more fully understood when their relations to other ideas of 
their time, and the history of their development are known and borne in 
mind. By development I do not merely mean their growth in the minds 
of those who first advanced them, but that larger development which 
consists in their subsequent good or evil fortunes--in their reception, 
favourable or otherwise, by those to whom they were presented. This is 
to an idea what its surroundings are to an organism, and throws much 
the same light upon it that knowledge of the conditions under which an 
organism lives throws upon the organism itself. I shall, therefore, begin 
this new work with a few remarks about its predecessors. 
I am aware that what I may say on this head is likely to prove more 
interesting to future students of the literature of descent than to my 
immediate public, but any book that desires to see out a literary 
three-score years and ten must offer something to future generations as
well as to its own. It is a condition of its survival that it shall do this, 
and herein lies one of the author's chief difficulties. If books only lived 
as long as men and women, we should know better how to grow them; 
as matters stand, however, the author lives for one or two generations, 
whom he comes in the end to understand fairly well, while the book, if 
reasonable pains have been taken with it, should live more or less 
usefully for a dozen. About the greater number of these generations the 
author
