Hope the religious will not see as a blasphemy for the ontological
interpretation considering the logos as the principle of order and

Indeed, the difference between formal logic and real life ontology is like
the distinction between mathematical abstraction and real world.
Some real life example. Of all global assets, equities, government bonds,
corporate bonds, natural resources, human assets, and real estate property,
residential and commercial, in the so-called developed economies 8 years
ago, the last one amounted to $ 54 trillion. And the biggest portion of the
total wealth was in land and buildings.
Here is the industry foundation classes ontology (format, specification)
developed by the International Alliance for Interoperability 5 years ago for
a multi-trillion AEC industry.
The IFC sees all entities as rooted and non-rooted entities. Rooted
entities, IfcRoot, is subdivided into: object definitions, relationships,
and property sets. IfcObjectDefinition addresses tangible object occurrences
and types, subdivided further into actors, controls, groups, products,
processes, and resources. IfcRelationship handles relationships among
objects, like as composition, assignment, connectivity, association, and
definition. IfcPropertyDefinition refers to the set of properties about
object occurrences or object types, and so on. The IFC is emerging as an
open interoperable format of facility/building information modeling
software, essentially changing the standard real property industry.
Just without clearly naming it, these big ideas come from the real life
ontology, which is sadly missing in all the hot discussions and formal
