It's true that the world around us is composed of nouns and verbs. Nouns are objects, entities. Verbs are relationships. The Sun and the Moon are nouns. The eclipse of the Sun by the Moon is a relationship. Nouns are permanent, verbs are transient.
The delusion of our perception is that this noun permanence dictates a verb invariance. In reality, there is no such thing as verb invariance. All relationships are dynamic, i.e. change in time.
Attaching to "permanent" objects encourages attachment to impermanent relationships.
Nouns are binary: they either exist or not.
Relationships are part of a continuum: they exist in various degrees.
That's what the network is about. The nodes are nouns, the arcs are verbs. The arcs are weighted ever-dynamic relationships. The nodes set the scene.
Relationships can be nominalized when "fossilized" in the network.
