Is Plato a logicist? A comparative study between The Republic and The Sofist shows at one side how Plato mantains the trascendence of Good over the rest of the Ideas conserving it in this manner not just like a form but as that which mades possible the Ideas and the inteligibility of all that is. On the other hand one notice in The Sofist that being which Plato is talking about is surely the being (and not being) of propositions. Being (...) is for Plato like an Idea, but this doesn't imply logicism because in his thought there's a place for a Foundation, a Principle -the Good- which trascends all the forms: which mades possible also "the seen" and seing itself.
