“For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.”

The problems that beset the modern world are complicated and nuanced. Thus any potential solutions will be equally complex and subtle. There are no quick fixes for issues such as climate change or nuclear proliferation and anyone trying to sell you one is either a charlatan or a fool. In his book, The Demon-Haunted World, Carl Sagan strongly advocates that adopting a scientific approach to thinking is essential in a modern democracy. By this he means questioning ideas critically and requiring evidence based arguments. If something cannot be effectively measured, tested or verified we should be deeply sceptical of it. He even goes so far as to argue that it is patriotic to ask questions and that any person, institution or organisation that avoids such scrutiny should be deemed suspect. Published in 1995 Sagan’s concerns regarding the coming century have proven sadly accurate. A quarter of a century ago, he predicted the rise of misinformation, fake news and alternative facts. When information is controlled and a population lacks critical thinking it becomes "unable to distinguish between what feels good and what’s true".
