 Carnap distinguished two kinds of questions that can be asked about what there is. One are the so-called ‘internal questions’, questions like ‘Are there infinitely many prime numbers?’ These questions make sense once a framework that contains talk about numbers has been adopted. Such questions vary in degree of difficulty. Some are very hard, like ‘Are there infinitely many twin prime numbers?’, some are of medium difficulty, like ‘Are there infinitely many prime numbers?’, some are easy like ‘Are there prime numbers?’, and some are completely trivial, like ‘Are there numbers?’. Internal questions are thus questions that can be asked once a framework that allows talk about certain things has been adopted, and general internal questions, like ‘Are there numbers?’ are completely trivial since once the framework of talk about numbers has been adopted the question if there are any is settled within that framework.
