Politician and founder of the 'Sense for Science' charity, Dick Taverne is more than just a writer debunking some of the worrying trends of our time (from the anti-GMO hysteria to organic farming, and alternative medicine to the anti-vaccination campaigns). He is, above all, a convinced militant eager to push his opinions and convictions in the public arena for decision-making. You might not agree with all of his preaching (although I, personally, do) but, you'll have to recognise here his balanced argumentation and fair play. Gosh! He's dedicating whole chapters outlining in details the arguments of his opponents, before dismissing them one by one mercilessly! Clearly referenced, well researched and sticking to facts, and only facts, there's no room here for emotional prejudices. Everything is about the science involved, only the science and, indeed, that's the key word, the one the whole book revolves around; the importance of the science only. Dick Taverne, once again from the vantage point of a politician and policy maker, insists on the importance of the evidence based approach in our assessing of risks to make the decisions impacting on us all. No hysteria, no prejudice. Whose agreeing with him or, familiar with his pleas (in support of GM crops, questioning the supposed benefits of organic farming, laughing at complementary treatments etc.) won't find anything new here. However, and that's what makes him stand out from the bunch of our so much needed debunkers, he goes beyond the demolishing of bullshit to remind us of the dangers involved when ignoring scientific evidence when taking crucial decisions regarding key societal issues. Indeed, a scientific approach (evidence based, the ability to question everything) is the cornerstone of democracy and progress; once it flies out off the window to make space for irrational thinking, prejudices and superstitions it can only lead to a new dark age (just think about the devastating consequences of the reject of GM crops on the developing world or, the effects of the anti-vaccination campaigns so far ...). Thus, this book is more than pointing fingers at and denouncing some fantasies. It's a rallying call: to defend science is to defend democracy. A great insight, and a strong argumentation.
