The Great Debate

On 30 June 1860 the Oxford University Museum of Natural History played host to a clash of ideologies that has gone down in history as the 'Huxley-Wilberforce Debate', or simply the 'Great Debate'.

Charles Darwin

Thomas Henry Huxley, nicknamed 'Darwin's bulldog', was championing Charles Darwin's revolutionary concept of evolution by natural selection, published less than a year before. Samuel 'Soapy Sam' Wilberforce, Bishop of Oxford, brought all the force of his theological training to upholding the idea of biblical creation. Both sides claimed victory, and the debate continues to this very day. But what really took place? The true story of what happened turns out to be more complicated than the well-known myth.

The myth
An account of the debate written thirty years after it happened has Wilberforce taunting Huxley by asking him whether 'it was through his grandfather or his grandmother that he claimed descent from a monkey?' Huxley supposedly whispered to Sir Benjamin Brodie: 'the Lord hath delivered him unto my hand' before replying, witheringly: 'If then the question is put to me whether I would rather have a miserable ape for a grandfather or a man highly endowed by nature and possessed of great means of influence and yet employs these faculties and that influence for the mere purpose of introducing ridicule into a grave scientific discussion, I unhesitatingly affirm my preference for the ape.' But eye-witness accounts delivered soon after the event tell a somewhat different story.

The protagonists
Thomas Henry Huxley (1825-1895) was a brilliant young biologist who had been welcomed into the heart of the scientific establishment first through his studies of invertebrate palaeontology and later of apes and humans. He was one of Darwin's closest associates, among the few to know of his ideas before the publication of On the Origin of Species. Reading it for the first time, he declared 'How extremely stupid not to have thought of that.'

Samuel Wilberforce

Samuel Wilberforce (1805-1873) was Bishop of Oxford, the summit of a highly successful career in the Church. He was known as an eloquent and influential speaker, mostly on clerical topics, but he also had a first class degree in mathematics and was a Fellow of the Royal Society. Before the confrontation took place he had written a review of Darwin's On the Origin of Species, in which he emphasised that his rejection of the theory was 'solely on scientific grounds', and that he had no sympathy with those whose objections were on the grounds that it contradicted what was 'taught by Revelation'.

The scene is set
The occasion was the annual meeting of the British Association for the Advancement of Science, an organisation established in 1831 with the far-sighted aim of encouraging public debate and understanding of scientific matters. Each year it held a public conference in a different city, attended largely by the well-to-do, but without the exclusivity of London's premier scientific academy, the Royal Society.

The meeting of 1860 marked the public inauguration of Oxford's new 'cathedral of science', the University Museum, and took place even before the collections had been fully installed or the architectural decorations completed. Darwin's On the Origin of Species by Means of Natural Selection had been published only seven months before. Darwin himself was absent. Always in uncertain health, he was taking a cure at Dr Lane's Hydropathic Clinic in Petersham, Surrey. The Bishop of Oxford, Samuel Wilberforce, was an Honorary Vice President of the meeting: he was already an implacable foe of evolutionary ideas, and had been tutored in his arguments by Richard Owen, the great anatomist and palaeontologist.

On Thursday 28 June Professor Charles Daubeny read a paper 'On the final causes of the sexuality in plants, with particular reference to Mr Darwin's work...' Owen countered with the exaggerated claim that the brain of a gorilla was more different from that of a human than from that of the lowest primate. Huxley was in the audience, and as he was known for using the similarity of ape and human brains as evidence of evolution, this was a blatant challenge. He got up and contradicted Owen flatly but politely. By Friday evening, exhausted by all the argument, Huxley intended to go home. But another evolutionist, Robert Chambers, begged him to stay on.

Saturday's meeting
On the Saturday morning the great and good of British science assembled together with a crowd of Oxford students, clerics, and local ladies and gentlemen in the library reading room, a large room on the first floor of the museum. The Rev. John Stevens Henslow, Darwin's Cambridge botany professor and lifelong friend, took the chair.

The main billing for Saturday's session was Dr John W. Draper of New York University, who read a long, boring paper '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'. After he had finished, Henslow called upon others to respond, some of whom received a noisy reception from the students. After this he allowed only the floor to those with arguments, not 'for mere declamation'.

Wilberforce then accepted an invitation to speak. He used the same arguments as were set in his anonymous review of The Origin, which was to appear in The Quarterly Review the following month. His rhetoric, now strictly logical, now witheringly dismissive, always flamboyant, carried the audience along - a majority was with him anyway, the ladies in the window waving their white handkerchiefs, the students in the rear cheering and jeering, the clerics smugly applauding. At the end of this all-out attack, Wilberforce added the one rhetorical flourish that has gone down in history. But what was it?

Insults traded
Three days after the debate took place, John Richard Green wrote about it to Sir William Boyd Dawkins. His letter records: 'Up rose Wilberforce and proceeded to act as the Smasher. The white chokers [clergymen] who were present cheered Samuel rattled on - "He had been told that Professor Huxley had said that he didn't see that it mattered much to a man whether his grandfather were an ape or no! Let the learned Professor speak for himself" and the like'.

July's issue of a popular journal, The Athenaeum, stated: 'The Bishop of Oxford came out strongly against a theory which holds it possible that man may be descended from an ape. But others - conspicuous among these, Prof. Huxley - have expressed their willingness to accept, for themselves, as well as for their friends and enemies, all actual truths, even the last humiliating truth of a pedigree not registered in the Herald's College.' Both of these accounts imply that the ape-grandfather metaphor had originally been coined by Huxley and not by Wilberforce.

Wilberforce sat down to tumultuous applause, and Huxley rose to reply. By his own account, in a letter to his friend Henry Dyster sent more than two months later, he told his audience that he 'had listened with great attention to the Lord Bishop's speech but had been unable to discover either a new fact or a new argument in it - except indeed the question raised as to my personal predilections in the matter of ancestry - That it would not have occurred to me to bring forward such a topic as that for discussion myself, but that I was quite ready to meet the Right Revd. Prelate even on that ground - If then, said I, the question is put... would I rather have a miserable ape...' and so on.

Green's account agrees: 'Huxley - young, cool, quiet, sarcastic, scientific in fact and in treatment... gave his Lordship such a smashing... "I asserted, and I repeat, that a man has no reason to be ashamed of having an ape for a grandfather. If there were an ancestor whom I should feel shame in recalling, it would rather be a man, a man of restless and versatile intellect, who, not content with... success in his own sphere of activity, plunges into scientific questions with which he had no real acquaintance, only to obscure them by an aimless rhetoric, and distract the attention of his hearers from the real point at issue by eloquent digressions and skilled appeals to religious prejudice."'

Hooker's contribution
Darwin's friend the botanist Joseph Hooker did not think the exchange worth mentioning when he wrote to tell Darwin what had passed. '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... The battle waxed hot. Lady Brewster fainted, the excitement increased as others spoke; my blood boiled... '

After hearing three more speakers, Hooker was sufficiently incensed to stand up himself. 'Now I saw my advantage; I swore to myself that I would smite that Amalekite, Sam, hip and thigh... and I handed my name up to the President as ready to throw down the gauntlet. ... [T]hen I smashed him amid rounds of applause... I ... proceeded to demonstrate: (1) that he could never had read your book, and (2) that he was absolutely ignorant of the rudiments of Bot. Science... Sam was shut up - had not one word to say in reply, and the meeting was dissolved forthwith.'

Hooker did not mention the ape-grandfather exchange which was the point where Huxley had his success. One detects a certain rivalry as to which disciple Darwin should love best. Hooker prided himself that he had 'been congratulated and thanked by the blackest coats and whitest stocks in Oxford.' But the Bishop certainly thought his prime opponent had been Huxley, not Hooker.

Who won?
All sides claimed to have won the day - Wilberforce wrote (to Sir Charles Anderson, 3 July 1860): '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.' Huxley observed that he himself was 'the most popular man in Oxford for a full four & twenty hours afterwards'. He left the meeting with new respect for the power of oratory, and later perfected the art and used it well on Darwin's behalf.

The encounter was sparsely reported at the time, which is why there is still confusion about who said what, but almost a century after it took place colourful accounts began to circulate that have given the occasion a greater significance than it may have merited on scientific or cultural grounds. Nonetheless, it was a dramatic moment that occurred right at the beginning of the Museum's history, and accordingly is commemorated both on a plaque outside the room where the debate took place, and on a stone plinth on the lawn outside.
