The history of Western culture is the history of the rise of the authority of ‘Reason-with-a-big-R’. Since the Enlightenment, we have come to believe that modes of knowledge that are guided by rationality are intrinsically more valuable, more ‘true’ than others. This is reflected in the power of scientific discourses in modern society: today, science occupies the throne which religion occupied in earlier times, as the key source of knowledge and truth. We have gained a lot of things in this process, including the many benefits that medical discoveries using rationalist scientific methods have brought us. But it is also important to ask ourselves: what have we lost? What has been pushed out by this historical march of Reason, what are we not seeing when we assume that rational thought automatically brings ‘progress’, and what areas of our human experience have come to be devalued?
