Abstract:

The Greek word for persuasion derives from the Greek verb 'to believe' Therefore, we can see that rhetoric may be argumentative but also expository (modes of discourse that seek to win acceptance of information or explanation). This understanding is critical for those of us who seek to accommodate technology or science to a user.
