These qualifications are intended to clarify the distinctive role of proper-name definiteness.
The book asks why initial identification should be associated with proper names when an article, annexation, relative construction, or other definite expression can also identify someone. The discussion differentiates naming by direct designation from reference that relies more obviously on an antecedent, a relation, a clause, or a further indication.
Important qualification: ‘Initially’ does not always mean the listener possesses absolutely no relevant prior knowledge. The issue concerns how the expression operates and which extra conditions or contextual supports are involved. Reading both the objection and the reply prevents an over-rigid interpretation.
