In other words, the definition is circular.

So, what distinguishes the first thing derived from thing from the second? Only what derives from them, in that case, again, your definitions are circular.

 
All these need definitions (what are part of truth=making) from OUTSIDE the system.

In other words, you are just ADMITTING, that everything in the model gets its "meaning" from EMPRICAL TRUTH as looking at the actual world, and derives from meaning from the "poorly defined" natural languages of that world.
So, NOTHING in that system has truth-makers in the system, and NOTHING is actually "analytically true" as everything fundamentally devolse to an empirical truth.

Fifteen story office buildings never wag their tail.
But there is not fundamental truth-maker to establish any of this.

In other words, your whole system is just based on emperical truth, and analytical truth doesn't actually exist.

Provide a counter-example.
it is always a type hierarchy.
Show me a word that isn't defined from other words, in other words, show me a root.
A tree with a root must either be infinite in depth or have cycles.

 
thus you can not trace them to a "root". We need to start with a set of first concepts that we agree OUTSIDE OF LANGUAGE what they mean, and express these definitions as loops within the language.

 This can be further simplified to types of relations between
finite strings.
And ultimately needs to rely on things not established by Truth-Makers in the system.

{Thing} is the root and is defined by itself constituents types of things.
So, it is either defined based on the ENGLISH sentence, and thus we pull enough of English into the system to define it, and get into the cycles of English, or
it is defined in terms of things that definie themselves on {Thing} and thus is circularly defined.

 
Only by using information from OUTSIDE the system.

Not at all.
Then you have cycles.

You ALWAYS need to reference something outside your system, and when you then include that source, you need to find the root of THAT system, and your problem continues.

So, if those constituents are in the system, we have a circular definition, and if outside, it isn't a self-sufficient system.
 A type hierarchy definitely does not have any cycles.
Most all of human knowledge that can be expressed using
language can be fully encoded as relations between finite
strings in a type hierarchy.
And doesn't have definitions in the system of its roots.

 Some knowledge requires specifying a sequence of procedural
steps. This requires sequence, selection and iteration.
And thus need definitions from outside the system, or cycles.

 The Cyc project uses GUIDs in place of finite strings.
This makes their system generic to all human knowledge.
I am sorry to say that Doug Lenat died last year.
 
But the definitions still need to either rely on cycles or things outside the system, or just remain undefined.
