Sure, but what I'm saying is that this doesn't happen in a way that allows your neurons to encode value for a 140-volt electrical shock. Perhaps you've already accepted this and find it obvious, but others (e.g. economists) do not. This kind of information about how the brain works constrains our models of human behavior, just like the stochasticity of neuron firing does.
But I'm not trying to show why encoding values for propositions is problematic. I'm trying to say that the brain does not encode values for objective intensities of stimuli.
Ah, understood.
Okay. I understand that it's a fact that the brain doesn't encode values for objective intensities of sensory stimuli. My puzzlement comes from when you say
I don't see the fact as an additional problem for a theory of human values. But there's no point in arguing about this, as I think we'd both agree that any theory of human values would have to accommodate the fact.
Hmmm. Maybe a clearer way to say it is just that this neurobiological finding further constrains our theories. I'll change the wording in the OP, thanks.
