Hi,
I agree with Martin's definition of phase and point of view of not "connecting a discussion about
"phases of ideas" with "phases of Physical Things".
I earlier thought myself that ideas, in some ways, could have 'phases' but it
seems more suitable, in the way of modeling adopted by the CRM, to say that
ideas (in the sense of propositional objects or of concepts/types — and what
about symbolic objects ?) exist as such, are identifiable as such, and do not
change in their identity over time. It seems to be our mind, our belief (CRMinf
I2 Belief), our mental state (Issue 359: mental state), that can evolve, i.e.
the substratum carries new ideas, our classification of concepts can change,
our belief, etc. but this would be about changing of mental state not
about changing of the ideas themselves, as such. Would this be the point ?
Would then, it this is correct, Mental state (not existing yet as class – Issue
359) and Belief I2 be subclasses of Exxx Phase ?
Another issue would be to ask if a E74 Group can have phases. Althogh the
identity of the group remains the same, it can have different 'behaviours',
strategies, situations, etc. This is of course related to social life, to an
ongoing, virtual CRMsoc extension. But insofar as 'Phase' is modelled as high
abstraction level class in CRMbase itself, wouldn't be appropriate to consider
also phases in the life of groups ?
If yes, then we would need one property pointing from the temporal entity
'Phase' to the object concerned by the specific appearence or characteristic
identifying the phase. But E74 Group and E18 Physical Things do not belong to
the same class, right? By the way I was wondering why E74 Group is not subclass
of Legal Object – E72. But if it was, this wouldn't arrange things, I assume,
because, ont the one side, having phases in not the intension of the Legal
Object class and, on the other side, there's the E90 Symbolic Object subclass
there which wouldn't seem to have 'phases'. Or does it have indeed ?
All the best

Dear Martin,
Would you want to tie the existence of a phase exclusively to E18 Physical
Things? One can imagine phases in the development of ideas as well....
Yes to both. As always, we do not model the term, here "phase", but try to define a distinct
concept we can associate with a clear-cut "behavior". Physical Things can be thought of as having a
simple trajectory through space-time: Any change makes the previous disappear. Therefore, substantial
evolutionary steps can be represented with a begin and ending on a time-line.That is a concept I can perceive
as a sort of "phase". Therefore the label.
The evolution of ideas, as any other immaterial thing, does not make previous
ideas disappear. I will be very happy to discuss what phases of ideas may be
confined to, whose they are, what sense of progress they have, and how we
perceive the social effect of ideas we would associate with phases.
Because of the above considerations, I suggest not to connect a discussion about "phases of
ideas" with "phases of Physical Things" (which include humans!!). I do not suggest
that phases of humans are restricted to material aspects. In my proposed definition, they may be
due to mental developments, as long as they characterize substantially the being.
All the best,
Martin

Dear All,
Here a first attempt to define "phase":
Exxx Phase
Subclass of: E2 Temporal Entity
Superclass of: E3 Condition State
Scope note: This class comprises phases during the existence and
evolution of an instance of E18 Physical Thing characterized by an appearance,
constitution or a behavior distinct from that in other times of its existence,
or distinct in the evolution of things of comparable kind, such as the
nestling, fledgling, juvenile and adult forms of birds, but some kinds of
phases may also be consequence of incidental changes such as accidents.
Best,
Martin
