Before revision:  For this we introduce energy levels for the concepts (words ) used in the story and we also introduce the new notion of 'cogniton' as the quantum of human language. Concepts (words ) are then cognitons in different energy states as it is the case for photons in different energy states,  states of different frequency radiation , when the considered boson gas would be light .
