But as soon as it exists in an environment in which cause and effect are realised the relation between apprehension of a thing and the stimuli of that thing would become unavoidably apparent and consistent from one brain to the next. A poke with a sharp stick - which I'm using as shorthand for type of signal interpreted by the brain from such a stimuli - will always be painful.
That, however, is demonstrably not true, as the brain can interpret one stimuli as something other than what is "normal." A sound can be interpreted by the brain as a smell. A pin prick can be interpreted as orgasm inducing, rather than painful. Pain and pleasure doesn't exist outside the brain.

Perhaps if the brain could apprehend objects in an environment in stasis then the objects could remain meaningless so long as the environment in which they are apprehended remains in stasis. As soon as cause and effect is allowed to act on them, however, they have meaning in the apprehension as the stimuli is processed in relation to the apprehension of the object.
What meaning? An asteroid hits another asteroid, and the forces act to cause the two to react -- whether break apart or change vector, etc. That's not "meaning." Cause and effect doesn't necessarily have any meaning. It just is. Gravity causes rivers to run downhill. Meaning? Nothing. It just is a bunch of molecules doing what the forces of nature require. A brain might think it's a nice river and be quite fond of it. It may have "meaning" to the brain, because maybe the brain grew up near the river and the brain gets all weepy thinking about the river. As such, that brain may find lots of meaning in the river. To General Tsao over in the Tsing Tao province of China, the river doesn't mean dick.
All meaning is meaning TO someone. There is no "meaning" inherent in a river or two asteroids hitting each other. They are just bunches of atoms.
“When I was in college, I took a terrorism class. ... The thing that was interesting in the class was every time the professor said ‘Al Qaeda’ his shoulders went up, But you know, it is that you don’t say ‘America’ with an intensity, you don’t say ‘England’ with the intensity. You don’t say ‘the army’ with the intensity,” she continued. “... But you say these names [Al Qaeda] because you want that word to carry weight. You want it to be something.” - Ilhan Omar
