The Scientific Importance of Free Speech by Adam Perkins at Quillette. I confess to not being sure what is going on here — having not read the apparently controversial earlier work of the author — but the article is prefaced by this “Editor’s Note: this is a shortened version of a speech that the author was due to give last month at King’s College London which was canceled because the university deemed the event to be too ‘high risk’.” You can find something of an explanation in this news report.
A quick Google search suggests that free speech is a regarded as an important virtue for a functional, enlightened society. For example, according to George Orwell: “If liberty means anything at all, it means the right to tell people what they do not want to hear.” Likewise, Ayaan Hirsi Ali remarked: “Free speech is the bedrock of liberty and a free society, and yes, it includes the right to blaspheme and offend.” In a similar vein, Bill Hicks declared: “Freedom of speech means you support the right of people to say exactly those ideas which you do not agree with”.
But why do we specifically need free speech in science? Surely we just take measurements and publish our data? No chit chat required. We need free speech in science because science is not really about microscopes, or pipettes, or test tubes, or even Large Hadron Colliders. These are merely tools that help us to accomplish a far greater mission, which is to choose between rival narratives, in the vicious, no-holds-barred battle of ideas that we call “science”.
