" 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.
How to Unsplit the World: Quantum mechanics, cognitive science, and the subject-
An interesting problem in the conception object-subject split is the photo-electric phenomena: in classical experience there is no current when the tension is under a certain value (object-subject split: the photon and the electron). In quantum mechanics there is always a probabilty to extract at least one electron from the cathod and it can reach the anod. The duration of extracting is kown about 1E-7 second so there is a cuurent not equal to zero eventhogh the tension is very low: a current about 1E-12 ampere (object-subjcet unsplit). This experience can be a way to determine the quantum of power.
About the 4-vector identity in Restreint Relativity see my article:

In tha same context see also my book:

It speaks about the new universal constant to be the links for the 4-vector identity.
