Essay 4: Rudolf Carnap, "Empiricism, Semantics, and Ontology". Carnap again, at the Carnap Corner. Note the three keywords: nothing wrong with ontology, as opposed to metaphysics (usually ontology is considered a BRANCH of metaphysics), but here Carnap is thinking 'internal questions'; semantics is truth-conditions; and empiricism is basic, observation statements.
Essay 6. John Wisdom, "Philosophical Perplexity". Wisdom is from Cambridge, and thus Rorty is extending the scope, including both Oxonian analysis and analysis from "the other place". What perplexed a Cambridge man may not perplex an Oxford man like Grice, though!
Grice, Way of Words, Harvard.
