In 2014, Prime Minister Narendra Modi told medical staff at a Mumbai hospital that the story of the Hindu god Ganesha – whose elephant head is attached to a human body – showed cosmetic surgery existed in ancient India.
I don’t comment much on Indian politics for two reasons. First, I think macroeconomic conditions and trajectories are more important than politics as such for a developing nation like India. Second, the details of the cultural and political dynamics within any given nation are really hard to grok from the outside.
That being said, the widespread percolation of this sort of pseudoscience and pseudohistory on the Indian Right is a problem and has analogs with instances in other nations (e.g., Mike Pence is almost certainly a Creationist). These beliefs are often (though not always) harmless in and of themselves, but they are indicative of deeper maladies in terms of epistemological hygiene.
I have Hindu nationalists who are broadly on the same empirical page as me. We differ on details of values and emphases. And I know they are somewhat embarrassed by these weird ideas about nuclear weapons in ancient India. The key is to keep a lid on it so it doesn’t capture the commanding heights (ergo, why I’m quoting Modi).
Addendum: One issue for me is that I have a hard time taking Indian pseudoscience seriously just as I have a hard time taking Creation Science seriously. Sincere, earnest, and sometimes bright, people taking absurd claims seriously and constructing models out of them strikes me as farcical and funny more than threatening.
