Pause and consider

A reading note

When a passage has been revised, keep the change itself available for inspection. Identify the wording that changed before deciding what the revision means. A clearer expression could preserve the earlier claim, while a changed condition could alter its scope. A newer version is therefore a place to continue reading, not a complete explanation of what happened between versions. If that history matters to your question, ask for the reason for the change and distinguish it from your own interpretation. This keeps a revision from becoming either an automatic reassurance or an automatic objection.

Questions to carry forward

  • Which wording changed, and does the change affect expression or the claim itself?
  • What explanation is offered for the revision rather than inferred from its existence?
  • Does my question concern the current passage or the reason it changed?
