ABSTRACT
Chapter 6 summarises the progress made over the previous five chapters and presents the general conclusions. These are essentially as follows. (1) By definition, every relative has a correlative, in relation to which it is said to be what it is. (2) Correlatives reciprocate and, therefore, are, in turn, said to be just what they are in relation to their relatives. (3) From these two principles, it follows that the existence of a relative implies the existence of its correlative and vice versa, so (contrary to what Aristotle says in Cat. 7) all relatives reciprocate as to implication of existence, including the two pairs that Aristotle claims to be exceptional in what regards natural simultaneity, namely knowledge/knowable and perception/perceptible. (4) However, from this it does not necessarily follow that all relatives are naturally simultaneous. For that, it would be necessary to exclude that some are the cause of the existence of their correlatives. But this may not be viable, because there arguably are relatives that, although reciprocating as to implication of existence with their correlatives, are, notwithstanding, the cause of their existence, as is the case, for instance, of the parent/child pair.
