Philosophies are tools for reasoning. I don't literally go through my life thinking "oh here's an undifferentiated quanta, time to apply some nouns to it." But if I want to adopt a scientific mindset it's beneficial to think in terms of the physical experience versus my mental model of it because I can write my mental model down, whereas I can't write physical experiences or undifferentiated quanta down. That's what makes them quanta.

We have tons of sayings for this like "the map is not the territory," "wherever you go that's where you are."
