It used to be, and indeed children are still taught in schools, that the advances that have been made in the last five hundred years (antibiotics, electricity, computers etc) resulted from the application of Science and its overthrow of dogmatic belief.
All ideas are put to the question in the auto da fe of experiment: Galileo’s observations versus the Inquistion’s biblical earth-centric world view and so forth. But over the same period, the power of belief (in Jesus, Marxism, Allah, perhaps ‘Economics’) has continued to flourish alongside the supposedly observation- based, empirical philosophy that we call Science.
Belief is strictly about what we cannot know but I am not going down the Dawkins black hole on this one since there are certainly some very odd things that science cannot explain. But I want to apply the philosopher Soren Kierkegaard’s approach to something that Science can explain and has: the health effects of ionising radiation.http://www.counterpunch.org/2016/01/13/nuclear-radiation-kierkegaard-and-the-philosophy-of-denial/
