Further, this science cannot be terribly extensive, for it does not deal with objects of reason, whose multiplicity;c is infinite, but merely with itself, with problems that spring entirely from its own womb, and that are not set before it by the nature of things that are distinct from it but through its own nature; so that, once it has become completely familiar with its own capacity in regard to the objects that may come before it in experience, then it must become easy to determine, completely and securely, thedomain and the bounds of its attempted use beyond all bounds of experience.
