Existence and Necessity (Unabridged)

It is clearly explained:


What it is for a statement to be necessarily true
Why necessity, possibility, existence, and non-existence are properties of propositions (truths and falsehoods), not of objects or states of affairs
What conditions a class of expressions must meet if the expressions belonging to it jointly constitute a single language
The significance for meta-linguistic research of the concepts of systematicity and productivity, as Chomsky defines these terms, and the relevance of these concepts to researches into the nature of necessity
Why Quine's attempt to prove the non-existence of analytic truth is not only false but self-defeating
Why empirical science relies on truths of purely conceptual, non-observational kind to organize the data at its disposal
