 Carnap applied this voluntaristic conceptual engineering in many different ways to many different problems, at different levels and on different scales. He applied it both within science and to larger problems about science (e.g., scientific language), or about the place of science in our lives. He applied it both to local reconstructions or explications of particular concepts (e.g., confirmation), and more globally, to entire language frameworks (see  section 1.2  below). And he wanted the local and global to fit together; precise definitions of explicated concepts were to be situated within such larger frameworks.
