Smiles, walks, dances, weddings, explosions, hiccups, hand-waves, arrivals and departures, births and deaths, thunder and lightning: the variety of the world seems to lie not only in the assortment of its ordinary citizens—animals and physical objects, and perhaps minds, sets, abstract particulars—but also in the sort of things that happen to or are performed by them. In the last few decades, this view has been a focus of considerable debate in philosophy, with implications reaching far into the concern of other disciplines as well, above all linguistics and the cognitive sciences. Indeed, there is little question that human perception, action, language, and thought manifest at least a prima facie commitment to entities of this sort:
Parties are similar to dances and weddings in that they are events that occur rather than take place. However, I can't find a way to distinguish them from the gerund partying. The article linked elaborated a bit on it in the Events vs Facts section, but I didn't really understand it.
Parties are fun.
Partying is fun.
I can't help but feel that there is something different between these two sentences.
