One of the best collection of essays I've ever read. Great if you want an introduction to logical analysis and logical positivism in its best and most accurate form. The following is a list of chapters that I believe are must-reads and that I will return to:
Is Existence a Predicate? Designation and Existence. The Semantic Conception of Truth (completely brilliant). On Sense and Nominatum. On Denoting.
Truth and Confirmation. Experience and Meaning. Meaning and Verification. The Scientific World-Perspective.
On the Nature of Mathematical Truth. Truth by Convention.
Is There a Factual a Priori? The Pragmatic Conception of the a Priori. Two Concepts of Probability.
The Refutation of Realism. Realism and the New Way of Words.
The "Nature" of a Continuant. The Contrary-to-Fact Conditional. Causality in Everyday Life and in Recent Science.
