Setting domain to instances of events is too restrictive

Latest comment: 11 years ago1 comment1 person in discussion

I've removed the template that set the domain of this property to instances of event. Much talk of causation does not construe its relata as events. Requiring (or inferring) the subjects of this property to be events would result in awkward formalisms.

This position has precedent (emphasis mine):

According to the philosophy researcher Jaegwon Kim (Kim 1993), any discussion of causation implies an ontological framework of entities among which causal relations are to hold, and also "an accompanying logical and semantical framework in which these entities can be talked about". He argues that the entities that represent either causes or effects are often events, but also conditions, states, phenomena, processes, and sometimes even facts, and that coherent causal talk is possible only within a coherent ontological framework of such states of affairs.
