inheres in at all times inheresInAt BFO2 Reference: independent continuant that is not a spatial region inheres-in_at BFO2 Reference: specifically dependent continuant Alan Ruttenberg: This is a binary version of a ternary time-indexed, instance-level, relation. The BFO reading of the binary relation 'inheres in at all times@en' is: forall(t) exists_at(x,t) -> exists_at(y,t) and 'inheres in@en(x,y,t)'. (iff (inheresInAt a b t) (and (DependentContinuant a) (IndependentContinuant b) (not (SpatialRegion b)) (specificallyDependsOnAt a b t))) // axiom label in BFO2 CLIF: [051-002] BFO 2 Reference: Inherence is a subrelation of s-depends_on which holds between a dependent continuant and an independent continuant that is not a spatial region. Since dependent continuants cannot migrate from one independent continuant bearer to another, it follows that if b s-depends_on independent continuant c at some time, then b s-depends_on c at all times at which a exists. Inherence is in this sense redundantly time-indexed.For example, consider the particular instance of openness inhering in my mouth at t as I prepare to take a bite out of a donut, followed by a closedness at t+1 when I bite the donut and start chewing. The openness instance is then shortlived, and to say that it s-depends_on my mouth at all times at which this openness exists, means: at all times during this short life. Every time you make a fist, you make a new (instance of the universal) fist. (Every time your hand has the fist-shaped quality, there is created a new instance of the universal fist-shaped quality.) b inheres_in c at t =Def. b is a dependent continuant & c is an independent continuant that is not a spatial region & b s-depends_on c at t. (axiom label in BFO2 Reference: [051-002]) specifically depends on at all times independent continuant spatial region specifically dependent continuant
