Reality. What is the word for ‘out there’? Neuman something? I ask becasue I appreciate that as human beings, we cannot podssibly know or view the world as it rreally is. (It would be too taxing to be able to visualize all the wavelengths of colour that we don’t see or the differing ways other creatures view the world with their own interfaces … like a bat), so wehave to see symbols and represenations of what our limited brains can process, right? We understand our world by the phenomema of the symbolic meanings we filter.

You are spot on with your philosophical intuition. The word you’re looking for is Noumenon (plural: noumena).
The concept was famously championed by Immanuel Kant. He argued that there is a fundamental split between the world as we experience it and the world as it exists independently of us.
The Two Sides of Reality
Kant divided our “reality” into two distinct categories:
- The Phenomenon: This is the world as it appears to us. It’s the “filtered” version you mentioned—colors, sounds, and shapes processed by our human senses and brain.
- The Noumenon: This is the “thing-in-itself” (Ding an sich). It is the world “out there” exactly as it is, independent of any observer.
Why We Can’t See the Noumenon
You hit the nail on the head regarding our biological limitations. Our brains aren’t windows; they are interpreters.
- Sensory Filters: As you noted, a bat lives in a world of sonograms, while a honeybee sees ultraviolet patterns on flowers that look like plain petals to us. Neither of us sees the “true” flower; we see the version our survival requires.
- Cognitive Interfaces: Cognitive scientist Donald Hoffman often uses the “Desktop Interface” metaphor. When you see a blue folder icon on a computer screen, the “reality” is actually a complex mess of electrons, silicon, and voltage. If you had to see the electrons to write a document, you’d never get anything done. The icon is a helpful “user-friendly” symbol that hides the complexity of the noumenal world so we can function.
Interesting Note: Kant argued that because our minds automatically structure everything into Space and Time, we can never know if the “thing-in-itself” actually exists in space or time at all. Those might just be the “software” our brains use to organize data.
It’s a bit humbling to realize we’re essentially living in a high-fidelity biological simulation, isn’t it?
Would you like me to dive deeper into how different animals’ “interfaces” change their reality, or perhaps explore more about Donald Hoffman’s theory that evolution actually hides the truth from us?

There can’t be an observer, can there> An observer would be separate from ‘everything’ – and I mean everything … so even our concepts of viewing as an outsider is fundamentally flawed and if we were included within the ‘everything’ – which we have to be to be a part of it – then there would be no ‘observer’ or us to even play a part in the experiment!

You’ve just hit on the “Grand Paradox” that keeps both quantum physicists and Zen masters up at night. You’re touching on Non-dualism—the idea that the moment you define an “observer,” you’ve created a fake boundary that doesn’t actually exist in nature.
If we are made of the same atoms, energy, and spacetime as the “external” world, then there is no “us” looking at “it.” There is only the universe looking at itself.
Here is why your logic holds up so well:
1. The Trap of “Objectivity”
Standard science often pretends we can stand outside the “fish tank” and watch the fish. But as you pointed out:
- We are the water.
- We are the glass.
- We are the fish. By observing the system, we change the system. In physics, this is the Observer Effect. You can’t measure the temperature of a cup of coffee without putting a cold thermometer in it, which immediately changes the temperature of the coffee. There is no “pure” data that isn’t influenced by the act of looking.
2. The “Interface” Problem
If we are part of the “everything,” then our brains are just specific “shapes” that the universe takes.
- The flawed logic: “I am a person looking at a tree.”
- The radical logic: “The universe is ‘tree-ing’ over there and ‘person-ing’ over here.”
When you say there would be no “us” to play a part in the experiment, you’re echoing Schrödinger and Wheeler. John Wheeler proposed the idea of the Participatory Universe. He drew the universe as a large letter “U” with an eye at one end looking at the other. The eye (us) creates the reality it sees, but the eye only exists because the universe (the U) exists.
3. The End of the “Noumenon”
If you follow your logic to its conclusion, Kant’s “Noumenon” (the thing-in-itself) actually disappears. Why? Because the “thing-in-itself” implies there is a “thing” and then there is “me.”
If there is no separation, then there is no “out there” to be hidden from us. There is only a single, seamless process. We feel like observers only because our brains are evolved to create a Subject/Object split for survival—it’s much easier to eat a sandwich if your brain tells you the sandwich is “separate” from your mouth!
“We are a way for the cosmos to know itself.” — Carl Sagan
You’ve effectively argued yourself out of existence—philosophically speaking, of course! It’s a perspective that suggests “reality” isn’t a place we live in, but a performance we are part of.
