“On the word of no one” is the Royal Society's motto. Authority, it contends, is nothing: evidence everything. Scientific papers, even by the most distinguished thinkers, should live or die by the facts alone.

This week senior members of the society forced the resignation of Michael Reiss, its director of education, after a speech in which - parts of the media implied - he advocated teaching creationism in schools. On the word of no one.

His speech is online, so let us assess the evidence. The first thing you notice is that, if this were a scientific paper, it is no Principia Mathematica. Its conclusions seem obvious: almost truistic. Professor Reiss, while strongly defending evolution, says that teachers should be respectful to creationist students and not ridicule their views - because it is counter-productive, and puts them off science. He concludes: “A student who believes in creationism has a non-scientific way of seeing the world, and one very rarely changes one's world view as a result of a 50-minute lesson.”

But take one sentence out of context, “creationism is best seen by science teachers not as a misconception but as a world view”, prefix it by explaining that Professor Reiss is a clergyman, and suddenly he is a creationist.

The strangest thing is that the Royal Society accepts that he has been badly treated. “Professor Michael Reiss's recent comments... were open to misinterpretation,” it says. “While it was not his intention, this has led to damage to the society's reputation. As a result, Professor Reiss and the Royal Society have agreed that, in the best interests of the society, he will step down immediately.”

So he resigned not because he was wrong, nor even because he was particularly controversial. He resigned because others ascribed to him beliefs that were not his own.

He is not the first. When the Archbishop of Canterbury, Rowan Williams, gave a 6,000-word lecture about Sharia in the UK, it was summarised in headlines implying that he advocated public executions and the stoning of women. When Patrick Mercer, the Conservative defence spokesman, talked about the use of the word “nigger” while he was in the Army, he was sacked - not for being racist, but for allowing people to think he might be.

In an odd pact between journalists who want to write sensation, and readers who want to buy it, we choose cartoonish half-truths over complex reality. Professor Reiss is the victim of a culture where all arguments must be expressible in a sentence, and all sentences able to stand on their own. But don't take my word for it: read the speech.
