| Position | Claim |
|---|---|
| Platonic suspicion | Rhetoric is flattery; it produces conviction without knowledge |
| Aristotelian integration | Rhetoric is the counterpart of dialectic; a legitimate art with its own rigour |
| Sophistic | Persuasion is the practical skill; truth-claims are less available than assumed |
| Modern rhetoric of inquiry | All disciplines persuade, including the sciences; the question is by what means |
| Manipulation-based distinction | The line is bypassing rational agency, not using emotion at all |
