“Science envy” and “math envy” are perennial problems across huge swathes of the academic world. Mathematics and the hard sciences are seen as having achieved great leaps forward in understanding the world, and thus become objects for emulation whether applicable or not. Greek symbols start to fill up journal pages. It doesn’t matter if they demonstrate the argument more rigorously, they just need to look impressively sciency. Economics is currently the most seriously-afflicted discipline, although the other social sciences are rapidly succumbing as massive datasets become available online.
This is nothing new. As their name suggests, the social sciences have been built up by wave after wave of this imitation throughout the 20th century. Or even further back. The scholastic theology of medieval Christianity was largely a centuries-long case of ‘logic envy’. Theologians discovered Aristotelian logic in the 12th century, and proceeded to apply it to the bible in mind-numbing detail.
The indian case is even more interesting. Here the discipline to be emulated was grammar, then far more advanced than any other branch of knowledge (and pretty damn impressive even in a modern context). Grammatical terminology and forms of argument cross over into most other disciplines.
