Meaning plops into existence.
It does not exist latent.
Does not exist without a perceiver.

It is not discovered, it is invented.

My claim: the apparatus for distinction is product of invention, not discovery. Invention of meaning is using (or co-opting) a system to perceive and act upon it.

Sometimes, we have no eye, and no ear, for distinction.
We cannot see the chemical gradients a bacteria does.
For it, there is meaning. For us, therein none.

So, things exist that are not distinguishable.
So, things exist, which have no meaning.
Meaning is only definable with an observer.

To Illustrate, a Behavioral Ecology Story:
Beavers protect their offspring from snakes by banging their tails.
That act dispels the snake.
The beavers invented a signal: banging tail.
The snakes respond and flee.

But it turns out that, according to research, the snakes shun from the heat, not from the noise or the sight or even the vibration, that the banging tails entail.
No infra-red vision beavers, AFAWK.

Essentially, Beavers cannot know, what the snakes perceive.
The meaning just exists, because the snake flees.
Not because the snake knows, what the beaver wants.

The meaning sent is not the meaning received.
But meaning is exchanged.
The participants behave meaningfully.
According to meanings they invented.
By being what they are.
