Problem: George Campbell built his rhetorical theory on a particular view of the human mind. We have seen something like this in the suggestions Plato made in Phaedrus about the nature of the human soul. Vico speculated about the mind's development in terms of rhetorical devices. What elements of these theories of the link between the mind and rhetoric do you find most useful and why? Provide an example of those ideas making sense of a rhetorical work.
