“The Dao that can be told is not the eternal Dao; The name that can be named is not the eternal name.”
- Laozi

Laozi opens the Dao De Jing by reminding us that ultimate reality cannot be captured by words, names, or ideas. He opens with the split.
3.
Is red an empirical idea?
Not every reality-based idea is empirical. Some of our most useful ideas—like love, number, and infinity—are grounded in the real world but reached through abstraction, pattern, and inference rather than direct observation.
4.
Does infinity exist?
Infinity is a powerful rational idea used to describe patterns, limits, and unending processes, but it is not something we directly observe as a completed physical object.
5.
Was math discovered or invented?
Math is discovered in the structure of the Material World but invented in the symbolic systems minds use to describe that structure.
