Re: [Obi-role-branch] is host a disposition (new name for thread)

how does this fit with tendency?  it seems that the two might overlap.  i prefer capability in place of tendency.
the whole question seems to rest on stochastic outcomes, which may or may not be known at the time of description.

Subject: Re: is host a disposition (new name for thread)

Will do my best to get myself up to speed on this conversation soon. 
In the mean time, the best we have been able to come up with regarding definitions for 'dispotion' etc., is in the attached.
We are working on adding a new subtype of realizable called 'capability' as in: this horse has the capability to pull 300 kg.
This seems not to be a function, role or disposition.
Getting clear on capability may help us to get clear also on susceptibility.
