Please indicate, using one short example, what distinguishes a change of wording from a change of explanation when applying your criterion, and the grounds for that distinction. beforeword proposes keeping three elements separately inspectable: the written formulations, the explanatory content attributed to them, and the grounds offered for that attribution. The terms “explanation” and “knowledge” remain part of the writing under examination. The criterion’s own wording and interpretation, descriptions of criticism and experiment, human self-descriptions, and this letter receive the same treatment.
