“We like to imagine that knowledge advances fact upon dispassionate fact to reveal precise and irrefutable truths. But there is hardly a better example of just how messy and emotional science can be than Wegener’s discovery of the vast, turbulent forces moving within the earth’s crust. As often happens when confronted with difficult new ideas, the establishment joined ranks and tore holes in his theories, mocked his evidence and maligned his character. It might have been the end of a lesser man, but as with the vicious battles over topics ranging from Darwinian evolution to climate change, the conflict ultimately worked to the benefit of scientific truth.”

“A debate has been recently published in the British Medical Journal about whether doctors should practice homoeopathy alongside evidence-based medicine. The debate came out in response to a study from the Australian Government’s National Health and Medical Research Council, which was released this March. It concluded that there was no reliable evidence that homoeopathy was effective in treating a range of health conditions.”

“Acupuncture was developed in a pre-scientific culture, before anything significant was understood about biology, the normal functioning of the human body or disease pathology. The healing practices of the time were part of what is called philosophy-based medicine, to be distinguished from modern science-based medicine. Philosophy-based systems began with a set of ideas about health and illness and based their treatments on those ideas.”
