I have a friend who's parents are atheists (I met them at a Unitarian church) but he converted to Islam, I think in part because he's subconsciously trying to piss off his father, who's an opinionated loudmouth (and they sort of have a similar temperament). That's beside the point I suppose. And he's very bright, he posted something about how his "research in grad school was on computational simulations of virus proteins" but he's starting to doubt that viruses exist because viruses are too small to be detected by a microscope. If that sounds crazy, all I can say is, I personally didn't go to grad school and I have no clue how to research such a thing, so I certainly can't challenge him (but I do believe viruses exist).

Anyway that's not the subject of this post. He challenged his Facebook friends to prove COVID-19 exists, and when I posted this article for him, he didn't respond to me, but told another commenter he didn't believe it (the last comment): [ncbi.nlm.nih.gov]

So I'm thinking, this is a misuse of philosophy. What do you all think?
