Tarski On Logical Notions
We try to explain Tarski’s conception of logical notions, as it emerges from a lecture of his, delivered in 1966 and published posthumously in 1986 (History and Philosophy of Logic, 7, pp. 143-154), a conception based on the idea of invariance. The evaluation of Tarski’s proposal leads us to consider an interesting (and neglected) reply to Skolem in which Tarski hints at his own point of view o...
متن کاملPart Two: Logical Consequence ≠ Necessary Truth Preservation 1.1 Meta-theoretic Argument #1: the Gödel/tarski Argument
I suspect that this paper is written in a way that doesn’t reflect how Field actually came to the views he has about the normativity of logic. It seems likely to me that first (i) Field convinced himself that the relation of logical consequence could not be (even co-extensional with) the relation of necessary truth preservation (NTP), for reasons he lays out in PART TWO of the paper, then (ii) ...
متن کاملThe Tractatus on Logical Consequence*
THE TRACTATUS ON LOGICAL CONSEQUENCE José L. Zalabardo ABSTRACT: I discuss the account of logical consequence advanced in Wittgenstein’s Tractatus. I argue that the role that elementary propositions are meant to play in this account can be used to explain two remarkable features that Wittgenstein ascribes to them: that they are logically independent from one another and that their components re...
متن کاملLogical Consequence
Introduction Whenever one asserts a claim of any kind, one engages in a commitment not just to that claim itself, but to a variety of other claims that follow in its wake, claims that, as we tend to say, follow logically from the original claim. To say that Smith and Jones are both great basketball players is to say something from which it follows that Smith is a great basketball player, that s...
متن کاملLogical Consequence and Logical Expressions
The pretheoretical notions of logical consequence and of a logical expression are linked in vague and complex ways to modal and pragmatic intuitions. I offer an introduction to the difficulties that these intuitions create when one attempts to give precise characterizations of those notions. Special attention is given to Tarski’s theories of logical consequence and logical constancy. I note tha...
