 At this stage, the structure of Brentano’s theory already leaves open several possible interpretations. Neither the significance of  (4)  nor of  (5)  in Brentano’s theory are completely clear. That is to say: it is not completely clear that Brentano actually needs these two claims for backing up his theory, in particular for backing up his claim that combining two ideas in thought is not necessary for making a judgement (=  claim 2).  While Brentano presents his theory as a single whole in which claims (2), (4), and (5) form a tight package. one may unravel that package and accept (2) on the basis of (4) alone or independently of (4) and (5) altogether.
