““As a consequence, scientists who are carefully reflective about their activity do not instinctively ask the question ‘Is it reasonable?’ as if they were confident beforehand what shape rationality had to take. We have noted how ‘unreasonable’, in classical Newtonian terms, the nature of light turned out to be.
