Community/Brandom: cannot be wrong as a whole in relation to standards - but certainly in relation to concepts.
Brandom: Error: to treat the I-we relationship instead of the I-you relationship as the basic social structure - not the community assesses the accuracy of the use of "yellow", but individual members do.
Objectivity/Fraud/Error/Brandom: objective truth conditions by social practice - then error by the whole community possible - but only with standards, not with concepts.
