Ever since the Enlightenment, western thinking has been dominated by binary reasoning: yes or no, 0 and 1, inside and outside, are fundamental paradigms. We are all familiar with Charles Dickens’ “A Tale of Two Cities” and C.P. Snow’s “The Two Cultures”. While binary thinking may be extremely helpful in certain areas – computer programming and establishing borders are prime examples – its obvious clarity may have limitations that can have negative consequences. Recent examples in Switzerland and Ukraine highlight the disadvantages.
