I have previously told the story of a respected elder statesman in the Zoology Department at Oxford when I was an undergraduate. For years he had passionately believed, and taught, that the Golgi Apparatus (a microscopic feature of the interior of cells) was not real: an artifact, an illusion. Every Monday afternoon it was the custom of the whole department to listen to a research talk by a visiting lecturer. One Monday the visitor was an American cell biologist who presented completely convincing evidence that the Golgi Apparatus was real. At the end of the lecture, the old man strode to the front of the lecture hall, shook the American by the hand and said – with passion – ”My dear fellow, I wish to thank you. I have been wrong these fifteen years.” We clapped our hands red. No fundamentalist would ever say that. In practice, not all scientists would. But all would pay lip service to it as an ideal – unlike, say, politicians who would probably condemn it as flip-flopping. The memory of the incident I have described still brings a lump to my throat.
