I'm not familiar with the Pirsigs, but I certainly do not consider the attitude in question to be lawyerlike. While lawyers do occasionally face philosophical conundrums, they also tend to have the desired answer known to them. This is considerably easier than to, say, set a prior for the domain of a model parameter, where your preferences are in a vague war between convenience and justice. The internal debate arises when working from first principles and finding too few.
