 Correlated with the categories of meanings are ontological categories; e.g., object, state of affairs, unit, plurality, number, and relation are (formal) categories that categorize objects, not meanings (Husserl 1913 [2000], 237). Categories of the two sorts are, according to Husserl, connected by ‘ideal laws’. Thus, for example, presumably objects are the ontological correlates of the meaning category of nominative expressions, properties are the ontological correlates of adjectival expressions, and states of affairs are the ontological correlates of propositions. So while Husserl does not (to my knowledge) explicitly lay out a method of discerning ontological categories, it may be that we can derive them by beginning from the above nonsense test for distinguishing meaning categories, and then shifting attention to the correlative ontological categories, since “pure truths concerning meaning can be transformed into pure truths concerning the object” (1913 [1962], 61).
