"when a science or commerce guy criticises top humanities and social science scholars, you know how mediocre they are in their own fields; and the vice-versa"
When Amartya Sen won the Nobel for Economics, many of his ideas, and less technical essays, started coming down from the high academic world to common readers. After casually flipping through them, a friend of mine, an IITian, and hence considered brilliant by everyone (including himself), told me that there is nothing great about his work, and anyone could do all that development thinking: a bit of probability, elementary mathematics, a lot of rhetoric, choice, equality and other everyday words. In other words, even a low-ranking engineering graduate from a mediocre Engineering College (In 1998, there were no world rankings of institutions, but in 2011, IIT Kanpur was ranked somewhere below 250 in the world), could presume that he was intellectually superior to a Nobel Prize winner in a social science discipline.
Through some strange twists, the Francesca Orsini affair has sparked a war of disciplines––more accurately, an assault on the humanities and social sciences––on social media and other platforms. It's a caricature of what CP Snow had once called the battle between "The Two Cultures". For it to be a genuine war, we need the best practitioners of both 'cultures' speaking to each other, understanding one another, and THEN critiquing each other. In an age of superspecialization, that seems hardly possible, and that is quite understandable.
I have no way of proving it, but I know it by intuition, that the best in any field will not berate the best in another field, even if their own ideas lead to very different conclusions. While we celebrate Dante's Ptolemaic geocentric world in his great epic, we do not say Copernicus and Gallileo, and the whole of modern science is a mere superstition. Tagore and J C Bose were friends, but Bose never wanted to write a lyric, and Tagore never wanted to do science. There were many challenges to Freud, including some from his own disciples, but Einstein never questioned Freud's intellect. So when a science or commerce guy criticises top humanities and social science scholars, you know how mediocre they are in their own fields; and the vice-versa.
