Rules for Critical Discussion

Rules for Critical Discussion
by Frans Van Eemeren & Rob Grootendorst,
taken from "Fundamentals of Critical Argumentation" by Douglas Walton,
Cambridge University Press, 2006.

1. Parties must not prevent each other from advancing or casting doubt on each
others viewpoints.

2. Whoever advances a viewpoint is obliged to defend it if asked to do so.

3. An attack on a viewpoint must represent the viewpoint that has really been
advanced by the protagonist.

4. A viewpoint may be defended or attacked only by advancing argumentation
that is relevant to that viewpoint.

5. A person can be held responsible for the unstated premises he leaves implicit
in his argument.

6. A viewpoint is regarded as conclusively defended only if the defense takes
place by means of argumentation based on premises accepted by the other party,
and it meets the requirements of Rule 8.

7. A viewpoint is regarded as conclusively defended only if the defense takes
place by means of arguments in which an argumentation scheme is correctly
applied.

8. A viewpoint is regarded as conclusively defended only if supported by a chain
of argumentation meeting the requirements of rules 6 and 7 and if the unstated
premises in the chain of argumentation are accepted by the other party.

9. A failed defense must result in the proponent withdrawing her thesis and a
successful defense must result in the respondent withdrawing his doubt about
the proponents thesis.

10. Formulations of questions and arguments must not be obscure, excessively
vague, or confusingly ambiguous and must be interpreted as accurately as
possible.
