" For example, there’s the symbol grounding
problem: how can representations come to mean anything about the world, when all we have
access to are other representations?"
There is a solution to this in which we should trust : a representation which have been confirmed by experience in a determined context can be transferred in another context with analog forms.
I can take the exemple of vacuum energy in quantum mechanics which can be treated with analog concepts of Planck model of the black body radiation.
