Alfred Tarski


The Semantic Conception of Truth and the Foundations of Semantics


Part I. Exposition


3. The Meaning of the Term “True”

 


 

Brief Summary:
Truth often is defined using the ‘correspondence theory’ in the following way: “A sentence is true if it designates an existing state of affairs.” But this and similar correspondence theory definitions are not clear and precise enough to suffice as definitions for truth, and thus we must seek something better.



Summary



Previously Tarski discussed the extension of the term true. We will now encounter more difficulties with the term’s meaning (or intension).


We use the term “ true” with many meanings and usages. So as philosophers we must specify the meaning we want to give it. (333)


Tarski will follow in the tradition of Aristotle, who wrote in his Metaphysics

To say of what is that it is not, or of what is not that it is, is false, while to say of what is that it is, or of what is not that it is not, is true.
(Aristotle, qt in Tarski, 333; Aristotle, gamma 7, 27)


Tarski reformulates this using modern terminology to say:

The truth of a sentence consists in its agreement with (or to) reality.
(333)

This is sometimes called the “correspondence theory of truth.” (333)


[Normally we might use the term ‘ designate’ to mean that some name or term stands for some object of reference. But also] we can think of whole sentences as designating states of affairs, and thus we could say:

A sentence is true if it designates an existing state of affairs.
(334)


Yet none of these definitions is precise and clear enough to suffice to define truth. Thus “It is up to us to look for a more precise expression of our intuitions. “ (334)
