New blogpost: Formal Methods in
Philosophy.
This is an entry I wrote five years ago for a handbook, but it hasn’t come out yet, so I figured it might be worth posting here. It’s sort of a paean to formal methods in philosophy. The idea was to give a sense of the variety and power of these methods.

Wow, thanks so much for showing me this "Art". Just what I needed - to be drawn more deeply into the World of Illusion.

A Castle for Christmas is set in ‘Dunbar’, which is near where I grew and it’s where my mum taught primary school for thirty years. However, in the film, a town of 10,000 people situated next to a nuclear power station has become a hamlet of 300 people with quaint stone bridges over babbling brooks.

any filmmakers on here interested in remaking Falling Down (1993) but instead of a traffic jam on a hot day the catalyst is trying to log in to editorial manager on literally any sort of day whatsoever?

I'm a philosopher interested in how our understanding of what it is to be a person can shape our understanding of the dynamics of interpersonal relationships and conflict of all kinds. Looking for new ways to connect three years after quitting X.

Minor league umpires have a higher accuracy rate on ball-strike calls than major league umpires but

Your Final Pre-Robo-Zone Umpire Accuracy Update
This is the last time we’ll get to judge umpire accuracy without the ABS challenge system. Where do umpires stand, and how might we expect their accuracy to change once the robots get involved?
