@jyoshimi I've lightly studied merology but otherwise I'm a naif.
@dougmerritt nice to meet you! I like mereology as a topic, since the "parts" of conscious experiences should somehow be related to the "parts" of brain activity, but what exactly a part is in each case is pretty subtle and mysterious (certainly NOT something like a Lego block). But I tend not to find much need for formal mereology in my work, beyond having a few concepts like mereological sum available. So basically I'm pretty noobish there too
@dougmerritt yeah I think there are reasonable applications there, and also in semantics. Barry Smith has done quite a bit of good work and he also has his formal ontology database modeling stuff (e.g. this:https://ontology.buffalo.edu/smith/IntroOntology_Course.htm) which is interesting, and another good application of the tools.
@dougmerritt Oops! cut off a char: https://ontology.buffalo.edu/smith/IntroOntology_Course.html
@jyoshimi Ah, thanks.
@jyoshimi That link is dead -- although his front page is chock full of ontology this that and the other.
