Acceptability/communicative action/Habermas: a speech act should be called "acceptable" if it fulfils the conditions so that a listener can say "yes". These conditions cannot be fulfilled unilaterally, neither speaker nor listener relative. Rather, they are conditions for the intersubjective recognition of a linguistic claim, which constitutes a content-specified agreement on liabilities that are relevant for the consequences of the interaction.
Within the theory of communicative action we start from the special case that the speaker literally means his statements. I call this case the standard conditions.
A speaker can rationally motivate a listener to accept if, due to an internal connection between validity, validity claim and redemption of the validity claim, he/she can guarantee to give convincing reasons, if necessary, which stand up to criticism of the validity claim. The binding force of illocutionary success does not then stem from the validity of what has been said, but from the coordination effect of the guarantee it offers to redeem the validity claim if necessary. This applies in cases where there is no claim to power but a validity claim._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
