Philosophical approaches: verbs and nouns in human mind
Verb is not a basic concept. It is actually made up of quite a lot of references to nouns. Therefore, you should be able to reduce a verb into a huge set of noun relationships to the verb itself. Therefore, human mind must work within the frame of nouns which can be directly mapped to a specific sense such as a vision, tactual sensation or sound in my opinion. Thus, if we assume this as a fact, flows or much more explicitly any concept including a temporal function cannot be mapped into a single sense including the time concept itself.
Hypothetically, the ‘time sense’ should not be a native feature of the human brain since this is case is correct. It could be probably related to an external sense but still valid within human body and mind. The beats of the heart is a great example for this and if the brain uses the heart beats as a time sense, all the flows are related to that concept which also makes them subjective. We can also empower the argument by giving a real life example. Children tend to feel time passes more whereas the adults feel it a little bit slower. The reality behind this example should be the decrease in the beat count while they are aging.
All in all, we can assume that verbs are not pure and simple concepts so they can be resolved into noun like words and therefore human mind may not be actually using flows. Instead, it could be more focused on static nouns which is a parallel theory to quantum today.
