40, The Problem of Retraction in Critical Discussion

Contents of 'The Problem of Retraction in Critical Discussion' (2001), by Erik C. W. Krabbe

In many contexts a retraction of commitment is frowned upon... But on the other hand, the very goal of critical discussion - resolution of a dispute - involves a retraction, either of doubt, or of some expressed point of view...

1, The Problem

2, Ingredients for a Solution

(i) Among the rules of dialogue there must be a number of retraction rules that determine, in each dialogical situation, which retractions are permissible...

(ii) If a retraction is permissible the rule should stipulate what, exactly, are the consequences of the retraction...

(iii) ... there must be different stipulations for different types of dialogue.

(iv) ... Retraction rules should take into account the type of persuasion dialogue in which they are to function...

(v) Even within one type of dialogue, there is a need for distinct retraction rules for each type of commitment that occurs within dialogues of that type...

(vi) Another distinction between types of commitment is that between light-side and dark-side commitments...

(vii) ... have a number of different models of dialogue for different types and situations...

(viii) ... it is advisable, in model construction, to make retraction just a bit costly. As was noted above, one might stipulate that retractions lead to further retractions...
