 By contrast, if the intentional act is empty, then it is a thinking act. In addition, if an intuition and a thinking act are directed to the same object in the same sense, they can “fuse”, to the effect that the intuition can be said to intuitively fulfill the empty act. Note one important implication of this view: since the presence of intuitive content is not essential for the act to be an objectifying act, every such act either is a signification or is always co-constituted by a signification. (It should not go unmentioned that Husserl modifies his view about this issue by arguing in later works that intuitions are not co-constituted by thinking acts, see Hua XVI §17; Hua XX/I, 85–98; Melle 2002.)
