I. The problem is when “non-arbitrary” aesthetic and ethical judgments become numerical since these judgments are pragmatic in nature. Rubrics are helpful because they allow instructors and students to make explicit what *they* mean by good writing. But to use a rubric to arrive at a grade is the hidden positivism in comp pragmatism.
II. The judge analogy is helpful with one obvious qualification: grading a paper does not set a precedent that future instructors are in some sense bound to (i.e., constrained by, exercise authority over), nor does a graded paper represent the present instructor’s obligation to a past instructor’s graded paper. That is to say, there is no specific example that constitutes normative status for past, present, and future instructors in the way that a judge’s decision does. Now in terms of quantification, even in the best case scenario, where the number, too, is seen as a language-game, i.e., pragmatically instituted by instructor(s), one can still suggest that the grade is an act of bad faith since the game contradicts itself: the number is used non-numerically!
III. A joke provides a good example for further clarification: Following Martin Pulido, a joke’s funniness isn’t in the joke itself but in the response to the joke. The response (laughter) is like an aesthetic or ethical claim, a kind of nonsense (no pun intended) that makes manifest the joke’s value; or, to sound more Wittgensteinian, a joke’s “funniness cannot be said only shown.” As Pulido writes, “The nonsense of value statements can never be used to justify a positivist claim that we should then turn to science’s subject matter, for then this ‘should’ is itself nonsensical as a value statement.” The “nonsense” that is aesthetic and ethical claims (e.g., “This is an excellent essay”) should not be measured in absolute terms, to which numerical assessment relegates [sic] nonsense. A grade tries to say what can only be shown.
