RT Journal Article T1 Completeness, categoricity and imaginary numbers: the debate on Husserl T2 Exhaustividad, categoricidad y números imaginarios: el debate sobre Husserl A1 Aranda Utrero, Víctor AB Husserl's two notions of "definiteness" enabled him to clarify the problem of imaginary numbers. The exact meaning of these notions is a topic of much controversy. A "definite" axiom system has been interpreted as a syntactically complete theory, and also as a categorical one. I discuss whether and how far these readings manage to capture Husserl's goal of elucidating the problem of imaginary numbers, raising objections to both positions. Then, I suggest an interpretation of "absolute definiteness" as semantic completeness and argue that this notion does not suffice to explain Husserl's solution to the problem of imaginary numbers.
