In the case of cellular communication, this issue of the object-word problem has bothered me for a while. Quorum sensing in bacteria as well. Horizontal gene transfer could probably account for some "cultural transmission." Generational language must somehow be encoded. Ghrelin as a universal "word" for hunger in mammalian cells is my go-to example. The process by which individual cells can intrude upon the consciousness of collective self is pretty interesting.

I don't know anything about that stuff, say more?

With the peptide hormone, Ghrelin, we have this neat interplay where the signaling molecule is released by stomach-based endocrine cells into the bloodstream. Eventually the signal is strong enough to reach the brain and stimulates feelings of hunger (or via suppression, fullness). I would consider this hormonal signal to be a crude word or phrase (Empty/more). It's shouted by cells loud enough to reach our awareness. Many might not consider that to be an object-word problem. But, I thought it odd that we take normal cellular communication lines for granted. Extra cellular vesicles are even more bizarre. They're almost like Uber/Lift freight storage truckers.

If I understand what you're saying, then I totally agree. It seems like people just accept that a certain molecule has, say, a dormitive potency because it puts people to sleep. It's more like the system uses the molecule to go to sleep. I may write more about this later.
