K. Fine: A Truthmaker Semantics for Conditional Imperatives
I provide a truth-maker semantics for conditional imperatives and indicate how it might be extended to other conditional constructions.
F. Moltmann: Underspecification of Attitudes and Truthmaker Semantics
It has been argued that the satisfaction conditions of a desire can be underspecified by the complement clause. This provides support for the view according to which the complement clause gives a partial content of the reported desire, where partial content is formulated in terms of truthmaker theory. In this talk, I will discuss the extent of such underspecification and whether it truly supports a truthmaker-based approach to the content of attitudes.
Optional preparatory reading here.
F. Faroldi: Truthmaker Semantics for Justification Logics – Open Problems
Justification logics are a family of logic where "implicit" modal operators are substituted by explicit terms to get formulas of the form t : A, where t could be evidence, a reason, etc. why A is known, believed, obligatory, etc., thus resulting in an “objectual” approach to modalities. In this talk we explore how to give a truthmaker semantics for justification logics, we provide some philosophical reasons to do so, and note some technical open problems.
Cian Dorr: Truthmaking in the Object Language
I consider a simple language with Boolean connectives, sentential variables and quantifiers binding them, and a connective for propositional identity (‘for it to be the case that … is for it to be the case that …’). Using familiar techniques, the possible-worlds model theory for such a language can be ‘internalised’ to derive a theory stated in the language itself, based on the definition of ‘world-proposition’ as ‘maximal consistent proposition’, and this theory can be shown to follow from the theory that propositions form a complete atomic Boolean algebra. In this paper, I will consider to what extent something similar can be done for Fine’s truthmaker semantics. This will involve looking for a way of picking out a class of special propositions to serve as surrogates for the states, and a binary relation among propositions to serve as a surrogate for the verification relation, and using these definitions to rewrite the metalinguistic definition of a model as theory in the object-language. I will make a start at considering to what extent the axioms of this theory can be derived from an independently natural weakening of the theory that propositions form a complete atomic Boolean algebra.
Ronald Dworkin’s work always spanned a wide array of topics, from the most abstract jurisprudence through the details of American constitutional law all the way over to political philosophy and theories of justice and equality. In the last decades of his life, however, Dworkin’s work flowered in ways that went beyond even this prodigious range. Though he continued his central work in the philosophy of law and constitutional theory, he also addressed issues in international law, human dignity, the philosophy of religion, the relation between ethics, morality and legal theory, and the unity of practical thought generally. This conference will explore some of these themes in Dworkin’s late work. Beginning with a panel on his understanding of religion, we will also convene discussions of his work on legal integrity, international law, and the relation between law and morality. There will be a total of nine presentations, with plenty of time for discussion. All are welcome.
Panel 1 (Friday 1:30 p.m.): Dworkin’s Religion without God.
Eric Gregory (Princeton),
Moshe Halbertal (NYU and Hebrew U.) Ronald Dworkin Religion Without God: Morality and the Transcendent
Larry Sager (Texas) Solving Religious Liberty
Panel 2 (Friday 4:30 p.m.): Dworkin on international law.
Samantha Besson (Fribourg)
The Political Legitimacy of International Law: Sovereign States and their International Institutional Order
John Tasioulas (King’s College, London)
Panel 3 (Saturday 10 a.m.): The idea of integrity in Law’s Empire.
Andrei Marmor (Cornell) Integrity in Law’s Empire
Jeremy Waldron (NYU) The Rise and Decline of Integrity
Panel 4 (Saturday 2:15 p.m.): Law and morality in Justice for Hedgehogs.
Mark Greenberg (UCLA)
What Makes a Moral Duty Legal? Dworkin’s Judicial Enforcement Theory Versus the Moral Impact Theory
Ben Zipursky (Fordham)

Although the Colloquium on Legal, Political, and Social Philosophy is on hiatus this year, it will convene a special “pop-up” session on Thursday, October 17 from 4-7 p.m. in the Faculty Library on the third floor of Vanderbilt Hall. Professor Joseph Raz, who has long been an important member of the Colloquium community, will present a pre-circulated paper on this occasion, which marks the end of many years during which he has taught regularly at Columbia Law School each fall. Professor Raz’s paper will be posted on the Colloquium website in due course.
Theoretical reasoning is a process by which we form doxastic states on the basis of our previously-held attitudes. One of the foundational questions about the nature of reasoning is with which mental states we can reason. Many discussions of reasoning assume that we can only reason with doxastic states such as beliefs. In this paper, I argue that we can also reason with imaginings. The argument has two parts. First, I argue that epistemic uses of the imagination instantiate a number of markers which, taken together, are very good evidence for a process counting as reasoning. These include (rule-based) operation on contents, the transmission of justification, transitions between mental states that we can be held epistemically responsible for, and the ability of imaginings to enter into explicit conscious deliberation. Second, I argue that reasoning with imagination is not reducible to reasoning with beliefs. Imaginings and beliefs make different kinds of epistemically appropriate transitions available. This is, in part, due to the distinctive way that imaginative episodes develop their content over time. Thus, the markers of reasoning that epistemic uses of the imagination instantiate cannot be explained away. One interesting upshot is that, although reasoning with imagination and reasoning with beliefs are quite psychologically different in certain important respects, they share an underlying epistemic structure.

The notion of an occurrence of a proposition in discourse is the subject of the following observation:
(O) A proposition may occur in discourse, now asserted, now unasserted, and yetbe recognizably the same proposition.
I shall argue that the true significance of this observation is utterly distorted by Geach’s manner of construing of it — a construal widely known today as “the Frege-Geach point”. Though it serves as a basis for a contemporary understanding of logical form, strictly thought through, this way of construing (O) can be shown to lead to absurdity. I will further argue that a straightforward, undistorted, acceptance of (O) is the key to a genuine philosophical logic.
