I agree.  I would use a dyadic relation named HasAttr to relate
an entity to something called an attribute of that entity.

An attribute of something is only an attribute when it is viewed
in the role of the second argument of a relation named 'HasAttr'.

Right, I have been saying the following on this forum for almost two years: 

being an attribute is, in human language, not a fixed feature of a word or a concept, except for some of the words in some minority of languages.  In others, 'beauty' and 'beautiful' and 'is beautiful' are expressed with exactly the same word, and the role in the sentence is market either by word position (in a positional language) or a particle that shows this (in a tagged language).  

In a very mongrel language like English, things are very complex, because multiple patterns are in play at the same time, on a word-by-word basis. For example, some words, like 'German', and the same as nouns and adjectives.  He is German, He is A German, while others that occupy the same semantic space, like English and Scottish, are not the same, but have to turn into English Person and Scot. 

 psycholinquists are examining how various language-related disabilities are manifested by speakers of different languages, and thus finding more about what is the same and different about the fundamental samenesses and differences between thinking and speaking in different languages.    They don't use entities, attributes, and relationships as their foundation, nor parts of speech like nouns and verbs.  They tend to use theta roles.

Given this, why would one want to insist that the fundamental organization of thought or a universal simple way to express propositions is based on entities, their attributes, and their relationships?

This raises the question about instances of blueness.  We'd like to say
the blue of your coat is darker than the blue of the sky.  So we need
to include instances of blueness in the ontology:  the HasAttr relation
relates a coat x to an instance of blueness y, which we can relate to
another instance of blueness z of the sky.

Yes, this is yet another role that 'blue' can plan.  It can be the name for a particular repeatable experience of blueness.

The blue of my coat is, if I understand correctly, what some metaphysicians are calling 'tropes' these days.

According to trope theory, the world consists (wholly or partly) of ontologically unstructured (simple) abstract particulars or, as they are normally called, tropes.  " Stanford Encyclopedia of Philosophy

That is, it is a particular but repeatable experience of blue.   And, in fact, if I understand, in this thought, 'my coat' is there just to locate the blue experience using a shared identifier, becasue the experience of that blueness, along with many other cues, is in fact one of the things that underlies constructing the coat in question out of our fundamental experiences.   Personally, I like this direction for metaphysics, in that it brings it closer to psychophysics and social psychology.

Good old Aristotle was quite clear about those issues.  He
distinguished the "substance" -- such as HumanBeing -- from the
"accidents" such as being blue or being a customer, vendor, etc.
For an Aristotelian description of George Washington, see slide 6
of http://www.jfsowa.com/talks/aristo.pdf

Yes, and this goes back to some previous discussions here about natural types, with which I also agree. 

But I have found it harder to sell that idea right off the bat than selling the understanding that some words used to describe things are actually describing roles of the things (customer, scoutmaster) , and others are not (person).

Thanks for this, John
