Frege regarded the extensions of concepts as logical objects and assumed not only that logic is committed to such objects but also that other kinds of abstract object, such as numbers, directions, shapes, and truth-values could be reduced to them. The inconsistency in his system, however, left him without a viable way to systematize extensions. In this paper, I formulate a general theory of logical objects by reducing`natural' extensions, `natural' numbers, directions, shapes, and truth-values… Expand
