This book was required reading for a philosophy of science course at McGill that I had to drop because of a scheduling conflict, and I've often regretted not taking it (It was taught by Mario Bunge, a quite famous philosophy professor with a PhD in physics, who held engineers in higher regard than scientists!). Getting back to the book... The central premise of this book is that science does not come naturally to human beings. We did not evolve to do science, but rather to survive in a hostile environment. Our brains contain a number of assumptions that are useful for survival, but turn out not to be true. Because of this, science is hard, and it requires a change in mindset to be able to do it properly. ( )
