Prior to human beings there were no objects, since objects arose with language. If we see a cat chasing and catching a mouse, then for Maturana the 'cat' is (not) eating the 'mouse'. Rather "it is flowing in the structural dynamics of its structural coupling/congruence in its domain of existence". The 'cat' does not exist as a 'cat' for the 'cat'. It cannot exist until somehow language arises for the cat.
