Hi Ferenc, I’m trying to understand why you apply space-time to identity recognition. If Aristotle had an idea (the syllogism), that idea is the same one we use today, and often debate the intricacies of on this list. Since it’s the same idea, but with a different space-time boundary, it seems identical to itself for that reason – time and space do not bound abstract concept objects like they sometimes do with physical objects.
There is no such thing as an abstract concept. A concept is the product of abstarction and sa such, it has form and content. Its form is its name, and its content is extension and intension which are likely to be changing by the passing of time. This should be obvious to you too.
But even there, the pottery shard made in Time and space are good bracketing properties for some applications, but not for all kinds of objects when identity is being modeled, IMHO. Re the observer’s relationship with the object, it seems that the <sign,interpretANT,interpretER> says it all; potentially, everyone could interpret any sign in any way they please. So identity in that universe has to be conditioned on who is doing the identification.
<sign,interpretANT,interpretER> may be translated as object relation and object, the three basic elements of an ontology. What I have been trying to point out for a long time now that Most of the ontologies use objects, properties and events and not seeing that events are the odd man out. Events are best described by verbs, but verbs do not lend themselves to the same classifications as objects and properties. On the other hand making them a noun "an abstract" thing does not lead you to materialize the desire of integrating ontologies, because it is not possible to fit verbal phrases with the ease allowed by spatial, static terms (nouns). verbs need to decompose the world in time and a proper ontology should reflect time, especially the start and end of the series of actions, etc. even if the slow passing of time and slow changes does not urge you to do so. But if tommorrow someone wants you to go metric, most of your knowledge is outdated overnigth, not to mention other issues that may be of the same import.
Thank You, ferenc
Thanks, -Rich Sincerely, Rich Cooper EnglishLogicKernel.com Rich AT EnglishLogicKernel DOT com 9 4 9 \ 5 2 5 - 5 7 1 2 From: ontolog-forum-bounces@xxxxxxxxxxxxxxxx [mailto:ontolog-forum-bounces@xxxxxxxxxxxxxxxx] On Behalf Of FERENC KOVACS Following the law of identity an object is identical with itself if it exists at a particular place in space and a particular point of time. This is like duplicating an object. So therefore two seemingly identical objects are only identical with each other, if we disregard space an time parameters. This is called abstarction, disaambiguation, decontextualization, etc. But if you accept that an object has two facets, namely form and content, or if you accept that no claim on identity may be made without including the aspect of the observer, then it must be clear, that either you have a new situation when the object is seen from a different aspect by the same observer, or you have another observer. Both of those aspects mean that you have a relation between the observer and the object observed, in other word the observer relates the object to him/herself. Since objects have names (even concepts do) which are forms, we are faced with the problem of defining and harmonizing the associated content (usually properties) in each observer to achive mutual understanding. I admit that space and time parameters may be dropped for some purpose, but as Physics teaches us, the aspect of the observer cannot. Otherwise you are all talking to yourselves. Ferenc
