But I always return to my fixed idea that it is dreadfully unphilosophical to publish without full details. I certainly think my future work in full would profit by hearing what my friends or critics (if reviewed) thought of the outline.
To any one but you I should apologise for such long discussion on so personal an affair; but I believe, and indeed you have proved it by the trouble you have taken, that this would be superfluous.
Yours truly obliged, CH. DARWIN.
P.S. What you say (for I have just re-read your letter) that the Essay might supersede and take away all novelty and value from any future larger Book, is very true; and that would grieve me beyond everything. On the other hand (again from Lyell's urgent advice), I published a preliminary sketch of the Coral Theory, and this did neither good nor harm. I begin MOST HEARTILY to wish that Lyell had never put this idea of an Essay into my head.
FROM A LETTER TO SIR C. LYELL [July, 1856].
"I am delighted that I may say (with absolute truth) that my essay is published at your suggestion, but I hope it will not need so much apology as I at first thought; for I have resolved to make it nearly as complete as my present materials allow. I cannot put in all which you suggest, for it would appear too conceited."
FROM A LETTER TO W.D. FOX. Down, June 14th [1856].
"...What you say about my Essay, I dare say is very true; and it gave me another fit of the wibber-gibbers: I hope that I shall succeed in making it modest. One great motive is to get information on the many points on which I want it. But I tremble about it, which I should not do, if I allowed some three or four more years to elapse before publishing anything..."
[The following extracts from letters to Mr. Fox are worth giving, as showing how great was the accumulation of material which now had to be dealt with.
June 14th [1856].
"Very many thanks for the capital information on cats; I see I had blundered greatly, but I know I had somewhere your original notes; but my notes are so numerous during nineteen years' collection, that it would take me at least a year to go over and classify them."
November 1856.
"Sometimes I fear I shall break down, for my subject gets bigger and bigger with each month's work."]
CHARLES DARWIN TO C. LYELL Down, 16th [June, 1856].
My dear Lyell,
I am going to do the most impudent thing in the world. But my blood gets hot with passion and turns cold alternately at the geological strides, which many of your disciples are taking.
Here, poor Forbes made a continent to [i.e., extending to] North America and another (or the same) to the Gulf weed; Hooker makes one from New Zealand to South America and round the World to Kerguelen Land. Here is Wollaston speaking of Madeira and P. Santo "as the sure and certain witnesses of a former continent." Here is Woodward writes to me, if you grant a continent over 200 or 300 miles of ocean depths (as if that was nothing), why not extend a continent to every island in the Pacific and Atlantic Oceans? And all this within the existence of recent species! If you do not stop this, if there be a lower region for the punishment of geologists, I believe, my great master, you will go there. Why, your disciples in a slow and creeping manner beat all the old Catastrophists who ever lived. You will live to be the great chief of the Catastrophists.
There, I have done myself a great deal of good, and have exploded my passion.
So my master, forgive me, and believe me, ever yours, C. DARWIN.
P.S. Don't answer this, I did it to ease myself.
CHARLES DARWIN TO J.D. HOOKER. Down [June] 17th, 1856.
...I have been very deeply interested by Wollaston's book ('The Variation of Species,' 1856.), though I differ GREATLY from many of his doctrines. Did you ever read anything so rich, considering how very far he goes, as his denunciations against those who go further: "Most mischievous," "absurd," "unsound." Theology is at the bottom of some of this.
