Chen’s concluding chapter is a full-fledged defense of Brown and Levinson against their critics. In terms of theoretical assumption, Chen argues that rationality, per Brown and Levinson, does not belong to Westerners only, neither is individualism monopolized by them. In terms of utility, Chen demonstrates that Brown and Levinson’s model of politeness is perfectly capable of accounting – and, in fact, was designed to account – for the dynamism of social interaction. The accusations that it cannot stems from an insufficient appreciation of the richness of the theory, particularly the formula for measuring the weightiness of face threat. The second part of the chapter is a critique of the research strand “politeness evaluation.” Chen argues that this strand suffers several weaknesses. It is proposed as a reaction to the norm-based approach in politeness research but ends up being norm-searching. It is meant to capture variation, but what it has offered the field is little more than a list of facts that were expected in the first place. Finally, it is claimed to investigate the “moment of evaluation,” but such a moment – the judgment of politeness at the time of speaking – is practically impossible to capture.
