"Problem solving requires continual translation between the state and process descriptions of the same complex reality." #readingToday  

_Problem solving requires continual translation between the state and process descriptions of the same complex reality. Plato, in the Meno, argued that all learning is remembering. He could not otherwise explain how we can discover or recognize the answer to a problem unless we already know the answer.23 Our dual relation to the world is the source and solution of the paradox. We pose a problem by giving the state description of the solution. The task is to discover a sequence of processes that will produce the goal state from an initial state. Translation from the process description to the state description enables us to recognize when we have succeeded. The solution is genuinely new to us—and we do not need Plato's theory of remembering to explain how we recognize it _
