Thomas Ricketts has developed a powerful interpretation of Frege on judgment, truth and logic. Recently, Ricketts has modified his reading, holding that judgment is an act of knowledge-acquisition; this rules out incorrect judgment. I argue that Ricketts goes too far here. I criticize the textual basis for Ricketts's new view, and show that the interpretive problems which led him to this change can be met without such extreme measures. Thus, I defend Ricketts' earlier view against his own later modification. Along (...) the way I discuss Kant and Brentano on judgment, and I explore Fregean argument concerning the objectivity of truth. (shrink)

The founder of modern logic and grandfather of analytic philosophy was 70 years old when he published his paper 'Der Gedanke' (The Thought ) in 1918. This essay contains some of Gottlob Frege's deepest and most provocative reflections on the concept of truth, and it will play a prominent role in my lectures. The plan for my lectures is as follows. What is it that is (primarily) true or false? 'Thoughts', is Frege's answer. In §1, I shall explain and defend (...) this answer. In §2, I shall briefly consider his enthymematic argument for the conclusion that the word 'true' resists any attempt at defining it. In §3, I shall discuss his thesis that the thought that things are thus and so is identical with the thought that it is true that things are thus and so. The reasons we are offered for this thesis will be found wanting. In §4, I shall comment extensively on Frege's claim that, in a non-formal language like the one I am currently trying to speak, we can say whatever we want to say without ever using the word 'true' or any of its synonyms. I will reject the propositional-redundancy claim, endorse the assertive-redundancy claim and deny the connection Frege ascribes to them. In his classic 1892 paper 'Über Sinn und Bedeutung' (On Sense and Signification) Frege argues that truth-values are objects. In §5, I shall scrutinize his argument. In §6, I will show that in Frege's ideography (Begriffsschrift) truth, far from being redundant, is omnipresent. The final §7 is again on truth-bearers, this time as a topic in the theory of intentionality and in metaphysics. In the course of discussing Frege's views on the objecthood, the objectivity of thoughts and the timelessness of truth(s), I will plead for a somewhat mitigated Platonism. (shrink)

Peter Carruthers; II*—Frege's Regress, Proceedings of the Aristotelian Society, Volume 82, Issue 1, 1 June 1982, Pages 17–32, https://doi.org/10.1093/aristoteli.

In his essay 'Thoughts',' Frege is to be found employing a regress-argument against the correspondence theory of truth. He seems to have felt that the argument is not only completely destructive of the correspondence theory, but that it could be deployed equally well against any attempt to provide a general definition of the notion of truth. In my view neither conclusion is warranted. But Frege's Regress can, nevertheless, be developed into an argument of the greatest significance.

For Frege’s general views about truth the standard reference is the first couple of pages of ‘The Thought’. Less attention has been paid to a short passage in ‘On Sense and Reference’ -- in, fact, only one paragraph long -- where Frege argues indirectly for the view that the relation between the thought and the True is an instance of the relation between sense and reference. He argues for this by discrediting the alternative view that it is an instance of (...) the relation between “subject and predicate”. Here is the paragraph: One might be tempted to regard the relation of the thought to the True not as that of sense to reference, but rather as that of subject to predicate. One can, indeed, say: ‘The thought, that 5 is a prime number, is true’. But closer examination shows that nothing more has been said than in the simple sentence ‘5 is a prime number’. The truth claim arises in each case from the form of the declarative sentence, and when the latter lacks its usual force, e.g. in the mouth of an actor upon stage, even the sentence ‘The thought that 5 is a prime number is true’ contains only a thought, and indeed the same thought as the simple ‘5 is a prime number’. It follows that the relation of the thought to the True may not be compared with that of subject and predicate. Subject and predicate (understood in the logical sense) are indeed elements of thoughts; they stand on the same level for knowledge. By combining subject and predicate, one reaches only a thought, never passes from sense to reference, never from thought to its truth value. One moves at the same level but never advances from one level to the next. A truth value cannot be part of a thought, any more than, say, the Sun can, for it is not a sense but an object. (Frege 1892, pp 34-35). Two subordinate, but still major, positive ideas are expressed in this passage. (shrink)
