Hayles et al. Let's turn now to N. Katherine Hayles's mapping of three waves of change. And Hayles, like others, is considering the conditions for the possibility of the Non-Human. We are attempting to get them to act in some way. If if they already agree or know, they are being persuaded or not, which is still a state of persuasion, that we know or do know or understand what it is that we are talking about.
Rhetorical theories are also general theories of change.
All of these, then, are theories of change on the largest level, but they focus on how human beings come to see themselves as bringing about the growth of knowledge. For in each there is an element or elements of other forces at work or play. The others also have similar ways of making the development of knowledge not solely or exclusively the result of human endeavor. At no time does KH, as most of the others above, present herself as a rhetorician. But anyone who reads the three editions of PF's book has got to know that PF is talking the basics of different kinds of rhetorics throughout.
