On June 30, 1860, the famous debate on Charles Darwin's theory of evolution was held at the Oxford University Museum which was dominated by arguments between Thomas Henry Huxley, Joseph Dalton Hooker, and Bishop Samuel Wilberforce. From the article:
"Word spread that Bishop Wilberforce, known as "Soapy Sam" (from a comment by Benjamin Disraeli that the Bishop's manner was "unctuous, oleaginous, saponaceous"), would speak against Darwin's theory at the meeting on Saturday 30 June 1860. Wilberforce was one of the greatest public speakers of his day[14] and, according to Bryson, "more than a thousand people crowded into the chamber; hundreds more were turned away."[15] Darwin himself was too sick to attend.[1]
The discussion was chaired by John Stevens Henslow, Darwin's former mentor from Cambridge. It has been suggested that Owen arranged for Henslow to chair the discussion "hoping to make the expected defeat of Darwin the more complete".[1] The main focus of the meeting was supposed to be a lecture by New York University's John William Draper, "On the Intellectual Development of Europe, considered with reference to the views of Mr. Darwin and others, that the progression of organisms is determined by law".[1] By all accounts, Draper's presentation was long and boring.[1][15] After Draper had finished, Henslow called on several other speakers, including Benjamin Brodie, the President of the Royal Society, before it was Wilberforce's turn.[1]
In a letter to his brother Edward, the ornithologist Alfred Newton wrote:
In the Nat. Hist. Section we had another hot Darwinian debate ... After [lengthy preliminaries] Huxley was called upon by Henslow to state his views at greater length, and this brought up the Bp. of Oxford ... Referring to what Huxley had said two days before, about after all its not signifying to him whether he was descended from a Gorilla or not, the Bp. chafed him and asked whether he had a preference for the descent being on the father's side or the mother's side? This gave Huxley the opportunity of saying that he would sooner claim kindred with an Ape than with a man like the Bp. who made so ill a use of his wonderful speaking powers to try and burke, by a display of authority, a free discussion on what was, or was not, a matter of truth, and reminded him that on questions of physical science 'authority' had always been bowled out by investigation, as witness astronomy and geology.
A lot of people afterwards spoke ... the feeling of the meeting was very much against the Bp.[16]
According to Lucas, "Wilberforce, contrary to the central tenet of the legend, did not prejudge the issue",[2] but he is in a minority on this, as Jensen makes clear.[17] Wilberforce criticised Darwin's theory on ostensibly scientific grounds, arguing that it was not supported by the facts, and he noted that the greatest names in science were opposed to the theory.[2] Nonetheless, Wilberforce's speech is generally only remembered today for his inquiry as to whether it was through his grandmother or his grandfather that Huxley considered himself descended from a monkey.
According to a letter written 30 years later to Francis Darwin,[18] when Huxley heard this he whispered to Brodie, "The Lord hath delivered him into mine hands".[19] This quotation first appears more than thirty years later, and is almost certainly a later insertion to the story. Huxley's own contemporary account, in a letter to Henry Dyster on September 9, 1860, makes no mention of this remark. Huxley rose to defend Darwin's theory, finishing his speech with the now-legendary assertion that he was not ashamed to have a monkey for his ancestor, but he would be ashamed to be connected with a man who used great gifts to obscure the truth.[2] Again, later retellings indicate that this had a tremendous effect on the audience, and Lady Brewster is said to have fainted.[1]
More reliable accounts indicate that although Huxley did respond with the "monkey" retort, the remainder of his speech was unremarkable. Balfour Stewart, a prominent scientist and director of the Kew Observatory, wrote afterward that, "I think the Bishop had the best of it."[20] Joseph Dalton Hooker, Darwin's friend and botanical mentor, noted in a letter to Darwin that Huxley had been largely inaudible in the hall:
Well, Sam Oxon got up and spouted for half an hour with inimitable spirit, ugliness and emptiness and unfairness ... Huxley answered admirably and turned the tables, but he could not throw his voice over so large an assembly nor command the audience ... he did not allude to Sam's weak points nor put the matter in a form or way that carried the audience.[21]
It is likely that the main point is accurate, that Huxley was not effective in speaking to the large audience. He was not yet an accomplished speaker and wrote afterward that he had been inspired as to the value of oration by what he witnessed in that meeting.
Next, Henslow called upon Admiral Robert FitzRoy, who had been Darwin's captain and companion on the voyage of the Beagle twenty-five years earlier. FitzRoy denounced Darwin's book and, "lifting an immense Bible first with both hands and afterwards with one hand over his head, solemnly implored the audience to believe God rather than man". He was believed to have said: "I believe that this is the Truth, and had I known then what I know now, I would not have taken him [Darwin] aboard the Beagle."[22]
The last speaker of the day was Hooker. According to his own account, it was he and not Huxley who delivered the most effective reply to Wilberforce's arguments: "Sam was shut up—had not one word to say in reply, and the meeting was dissolved forthwith"[23] Ruse claims that "everybody enjoyed himself immensely and all went cheerfully off to dinner together afterwards".[24]
It is said that during the debate, two Cambridge dons happened to be standing near Wilberforce, one of whom was Henry Fawcett, the recently blinded economist. Fawcett was asked whether he thought the bishop had actually read the Origin of Species. "Oh no, I would swear he has never read a word of it", Fawcett reportedly replied loudly. Wilberforce swung round to him scowling, ready to recriminate, but stepped back and bit his tongue on noting that the protagonist was the blind economist. (See p. 126 of Janet Browne (2003) Charles Darwin: The Power of Place.)
Notably, all three major participants felt they had had the best of the debate. Wilberforce wrote that, "On Saturday Professor Henslow ... called on me by name to address the Section on Darwin's theory. So I could not escape and had quite a long fight with Huxley. I think I thoroughly beat him."[25] Huxley claimed "[I was] the most popular man in Oxford for a full four & twenty hours afterwards." Hooker wrote that "I have been congratulated and thanked by the blackest coats and whitest stocks in Oxford."[1] Wilberforce and Darwin remained on good terms after the debate."
