A model is a so-called 'structure': https://plato.stanford.edu/entries/model-theory/ But allowable structures, typically mathematical entities in the model theories of many, are only material (physical) entities in the model theory of Hartry Field. For example, a model of arithmetic could be an actual semiconductor logic gate chip with RAM. @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
