           supertype:  cyc#temporal_thing  The collection of all things that have temporal extent or location, i.e. things about which one might sensibly ask When? . cyc#TemporalThing thus contains many kinds of things, including events, physical objects, agreements, and abstract pieces of time. Note that cyc#TimePoint is a specialization of cyc#TemporalThing, since time points have temporal location, although they arguably lack temporal extent. Abstract things that are timeless -- such as mathematical sets, attributes, and numbers -- are of course _not_ instances of cyc#TemporalThing.

                             supertype:  cyc#intangible  The collection of things that are not physical -- are not made of, or encoded in, matter. Every cyc#Collection is a cyc#intangible (even if its instances are tangible), and so are some cyc#individuals.  Caution: do not confuse `tangibility' with `perceivability' -- humans can perceive light even though it's intangible--at least in a sense.
                                supertype:  cyc#partially_intangible__partiallyintangible  The collection of things that either are wholly intangible (see cyc#Intangible) or have at least one intangible (i.e. immaterial) part (see cyc#intangibleParts). This includes intangible individuals, such as instances of cyc#Number-General  or cyc#Agreement, as well as non-individuals (all of which are intangible), i.e. instances of cyc#SetOrCollection.  It also includes things that have both tangible and intangible components (see cyc#CompositeTangibleAndIntangibleObject),  such as a printed copy of a newspaper (as its information content is intangible) or a person (as her mental states are intangible).
