[The following letter, from Mrs. Boole, is one of those referred to in the last letter to Sir J.D. Hooker:]
Dear Sir,
Will you excuse my venturing to ask you a question, to which no one"s answer but your own would be quite satisfactory?
Do you consider the holding of your theory of Natural Selection, in its fullest and most unreserved sense, to be inconsistent--I do not say with any particular scheme of theological doctrine--but with the following belief, namely:--
That knowledge is given to man by the direct inspiration of the Spirit of G.o.d.
That G.o.d is a personal and Infinitely good Being.
That the effect of the action of the Spirit of G.o.d on the brain of man is especially a moral effect.
And that each individual man has within certain limits a power of choice as to how far he will yield to his hereditary animal impulses, and how far he will rather follow the guidance of the Spirit, who is educating him into a power of resisting those impulses in obedience to moral motives?
The reason why I ask you is this: my own impression has always been, not only that your theory was perfectly COMPATIBLE with the faith to which I have just tried to give expression, but that your books afforded me a clue which would guide me in applying that faith to the solution of certain complicated psychological problems which it was of practical importance to me as a mother to solve. I felt that you had supplied one of the missing links--not to say THE missing link--between the facts of science and the promises of religion. Every year"s experience tends to deepen in me that impression.
But I have lately read remarks on the probable bearing of your theory on religious and moral questions which have perplexed and pained me sorely.
I know that the persons who make such remarks must be cleverer and wiser than myself. I cannot feel sure that they are mistaken, unless you will tell me so. And I think--I cannot know for certain--but I THINK--that if I were an author, I would rather that the humblest student of my works should apply to me directly in a difficulty, than that she should puzzle too long over adverse and probably mistaken or thoughtless criticisms.
At the same time I feel that you have a perfect right to refuse to answer such questions as I have asked you. Science must take her path, and Theology hers, and they will meet when and where and how G.o.d pleases, and you are in no sense responsible for it if the meeting-point should still be very far off. If I receive no answer to this letter I shall infer nothing from your silence, except that you felt I had no right to make such enquiries of a stranger.
[My father replied as follows:]
Down, December 14, [1866].
Dear Madam,
It would have gratified me much if I could have sent satisfactory answers to your questions, or, indeed, answers of any kind. But I cannot see how the belief that all organic beings, including man, have been genetically derived from some simple being, instead of having been separately created, bears on your difficulties. These, as it seems to me, can be answered only by widely different evidence from science, or by the so-called "inner consciousness." My opinion is not worth more than that of any other man who has thought on such subjects, and it would be folly in me to give it. I may, however, remark that it has always appeared to me more satisfactory to look at the immense amount of pain and suffering in this world as the inevitable result of the natural sequence of events, i.e. general laws, rather than from the direct intervention of G.o.d, though I am aware this is not logical with reference to an omniscient Deity. Your last question seems to resolve itself into the problem of free will and necessity, which has been found by most persons insoluble. I sincerely wish that this note had not been as utterly valueless as it is. I would have sent full answers, though I have little time or strength to spare, had it been in my power. I have the honour to remain, dear Madam,
Yours very faithfully, CHARLES DARWIN.
P.S.--I am grieved that my views should incidentally have caused trouble to your mind, but I thank you for your judgment, and honour you for it, that theology and science should each run its own course, and that in the present case I am not responsible if their meeting-point should still be far off.
[The next letter discusses the "Reign of Law," referred to a few pages back:]
CHARLES DARWIN TO C. LYELL. Down, June 1 [1867].
... I am at present reading the Duke, and am VERY MUCH interested by him; yet I cannot but think, clever as the whole is, that parts are weak, as when he doubts whether each curvature of the beak of humming-birds is of service to each species. He admits, perhaps too fully, that I have shown the use of each little ridge and shape of each petal in orchids, and how strange he does not extend the view to humming-birds. Still odder, it seems to me, all that he says on beauty, which I should have thought a nonent.i.ty, except in the mind of some sentient being. He might have as well said that love existed during the secondary or Palaeozoic periods.
I hope you are getting on with your book better than I am with mine, which kills me with the labour of correcting, and is intolerably dull, though I did not think so when I was writing it. A naturalist"s life would be a happy one if he had only to observe, and never to write.
We shall be in London for a week in about a fortnight"s time, and I shall enjoy having a breakfast talk with you.
Yours affectionately, C. DARWIN.
[The following letter refers to the new and improved translation of the "Origin," undertaken by Professor Carus:]
CHARLES DARWIN TO J. VICTOR CARUS. Down, February 17 [1867].
My dear Sir,
I have read your preface with care. It seems to me that you have treated Bronn with complete respect and great delicacy, and that you have alluded to your own labour with much modesty. I do not think that any of Bronn"s friends can complain of what you say and what you have done. For my own sake, I grieve that you have not added notes, as I am sure that I should have profited much by them; but as you have omitted Bronn"s objections, I believe that you have acted with excellent judgment and fairness in leaving the text without comment to the independent verdict of the reader. I heartily congratulate you that the main part of your labour is over; it would have been to most men a very troublesome task, but you seem to have indomitable powers of work, judging from those two wonderful and most useful volumes on zoological literature ("Bibliotheca Zoologica," 1861.) edited by you, and which I never open without surprise at their accuracy, and grat.i.tude for their usefulness. I cannot sufficiently tell you how much I rejoice that you were persuaded to superintend the translation of the present edition of my book, for I have now the great satisfaction of knowing that the German public can judge fairly of its merits and demerits...
With my cordial and sincere thanks, believe me,
My dear Sir, yours very faithfully, CH. DARWIN.
[The earliest letter which I have seen from my father to Professor Haeckel, was written in 1865, and from that time forward they corresponded (though not, I think, with any regularity) up to the end of my father"s life. His friendship with Haeckel was not nearly growth of correspondence, as was the case with some others, for instance, Fritz Muller. Haeckel paid more than one visit to Down, and these were thoroughly enjoyed by my father. The following letter will serve to show the strong feeling of regard which he entertained for his correspondent--a feeling which I have often heard him emphatically express, and which was warmly returned. The book referred to is Haeckel"s "Generelle Morphologie," published in 1866, a copy of which my father received from the author in January 1867.
Dr. E. Krause ("Charles Darwin und sein Verhaltniss zu Deutschland,"
1885.) has given a good account of Professor Haeckel"s services to the cause of Evolution. After speaking of the lukewarm reception which the "Origin" met with in Germany on its first publication, he goes on to describe the first adherents of the new faith as more or less popular writers, not especially likely to advance its acceptance with the professorial or purely scientific world. And he claims for Haeckel that it was his advocacy of Evolution in his "Radiolaria" (1862), and at the "Versammlung" of Naturalists at Stettin in 1863, that placed the Darwinian question for the first time publicly before the forum of German science, and his enthusiastic propagandism that chiefly contributed to its success.
Mr. Huxley, writing in 1869, paid a high tribute to Professor Haeckel as the Coryphaeus of the Darwinian movement in Germany. Of his "Generelle Morphologie," "an attempt to work out the practical application" of the doctrine of Evolution to their final results, he says that it has the "force and suggestiveness, and... systematising power of Oken without his extravagance." Professor Huxley also testifies to the value of Haeckel"s "Schopfungs-Geschichte" as an exposition of the "Generelle Morphologie"
"for an educated public."
Again, in his "Evolution in Biology" (An article in the "Encyclopaedia Britannica," 9th edition, reprinted in "Science and Culture," 1881, page 298.), Mr. Huxley wrote: "Whatever hesitation may, not unfrequently, be felt by less daring minds, in following Haeckel in many of his speculations, his attempt to systematise the doctrine of Evolution, and to exhibit its influence as the central thought of modern biology, cannot fail to have a far-reaching influence on the progress of science."
In the following letter my father alludes to the somewhat fierce manner in which Professor Haeckel fought the battle of "Darwinismus," and on this subject Dr. Krause has some good remarks (page 162). He asks whether much that happened in the heat of the conflict might not well have been otherwise, and adds that Haeckel himself is the last man to deny this. Nevertheless he thinks that even these things may have worked well for the cause of Evolution, inasmuch as Haeckel "concentrated on himself by his "Ursprung des Menschen-Geschlechts," his "Generelle Morphologie," and "Schopfungs-Geschichte," all the hatred and bitterness which Evolution excited in certain quarters," so that, "in a surprisingly short time it became the fashion in Germany that Haeckel alone should be abused, while Darwin was held up as the ideal of forethought and moderation."]
CHARLES DARWIN TO E. HAECKEL. Down, May 21, 1867.
Dear Haeckel,
Your letter of the 18th has given me great pleasure, for you have received what I said in the most kind and cordial manner. You have in part taken what I said much stronger than I had intended. It never occurred to me for a moment to doubt that your work, with the whole subject so admirably and clearly arranged, as well as fortified by so many new facts and arguments, would not advance our common object in the highest degree. All that I think is that you will excite anger, and that anger so completely blinds every one, that your arguments would have no chance of influencing those who are already opposed to our views.
Moreover, I do not at all like that you, towards whom I feel so much friendship, should unnecessarily make enemies, and there is pain and vexation enough in the world without more being caused. But I repeat that I can feel no doubt that your work will greatly advance our subject, and I heartily wish it could be translated into English, for my own sake and that of others. With respect to what you say about my advancing too strongly objections against my own views, some of my English friends think that I have erred on this side; but truth compelled me to write what I did, and I am inclined to think it was good policy. The belief in the descent theory is slowly spreading in England (In October 1867 he wrote to Mr. Wallace:--"Mr. Warrington has lately read an excellent and spirited abstract of the "Origin" before the Victoria Inst.i.tute, and as this is a most orthodox body, he has gained the name of the Devil"s Advocate. The discussion which followed during three consecutive meetings is very rich from the nonsense talked. If you would care to see the number I could send it you."), even amongst those who can give no reason for their belief. No body of men were at first so much opposed to my views as the members of the London Entomological Society, but now I am a.s.sured that, with the exception of two or three old men, all the members concur with me to a certain extent. It has been a great disappointment to me that I have never received your long letter written to me from the Canary Islands. I am rejoiced to hear that your tour, which seems to have been a most interesting one, has done your health much good. I am working away at my new book, but make very slow progress, and the work tries my health, which is much the same as when you were here.
Victor Carus is going to translate it, but whether it is worth translation, I am rather doubtful. I am very glad to hear that there is some chance of your visiting England this autumn, and all in this house will be delighted to see you here.
Believe me, my dear Haeckel, Yours very sincerely, CHARLES DARWIN.
CHARLES DARWIN TO F. MULLER. Down, July 31 [1867].
My dear Sir,
I received a week ago your letter of June 2, full as usual of valuable matter and specimens. It arrived at exactly the right time, for I was enabled to give a pretty full abstract of your observations on the plant"s own pollen being poisonous. I have inserted this abstract in the proo-sheets in my chapter on sterility, and it forms the most striking part of my whole chapter. (In "The Variation of Animals and Plants.") I thank you very sincerely for the most interesting observations, which, however, I regret that you did not publish independently. I have been forced to abbreviate one or two parts more than I wished... Your letters always surprise me, from the number of points to which you attend. I wish I could make my letters of any interest to you, for I hardly ever see a naturalist, and live as retired a life as you in Brazil. With respect to mimetic plants, I remember Hooker many years ago saying he believed that there were many, but I agree with you that it would be most difficult to distinguish between mimetic resemblance and the effects of peculiar conditions. Who can say to which of these causes to attribute the several plants with heath-like foliage at the Cape of Good Hope? Is it not also a difficulty that quadrupeds appear to recognise plants more by their [scent] than their appearance? What I have just said reminds me to ask you a question. Sir J. Lubbock brought me the other day what appears to be a terrestrial Planaria (the first ever found in the northern hemisphere) and which was coloured exactly like our dark-coloured slugs. Now slugs are not devoured by birds, like the sh.e.l.l-bearing species, and this made me remember that I found the Brazilian Planariae actually together with striped Vaginuli which I believe were similarly coloured. Can you throw any light on this? I wish to know, because I was puzzled some months ago how it would be possible to account for the bright colours of the Planariae in reference to s.e.xual selection. By the way, I suppose they are hermaphrodites.
Do not forget to aid me, if in your power, with answers to ANY of my questions on expression, for the subject interests me greatly. With cordial thanks for your never-failing kindness, believe me,
Yours very sincerely, CHARLES DARWIN.
