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.
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.

Reception to follow.
The NYU Center for Bioethics is pleased to welcome submissions of abstracts for its 1st Annual Philosophical Bioethics Workshop, to be held at NYU on Friday, April 3, 2020.
We are seeking to showcase new work in philosophical bioethics, including (but not limited to) neuroethics, environmental ethics, animal ethics, reproductive ethics, research ethics, ethics of AI, data ethics, and clinical ethics.
Our distinguished keynote speaker will be Frances Kamm.
There will be four additional slots for papers chosen from among the submitted abstracts, including one slot set aside for a graduate student speaker. The most promising graduate student submission will be awarded a Graduate Prize, which includes coverage of travel expenses (up to $500, plus accommodation for two nights) as well as an award of $500. Please indicate in your submission email whether you would like to be considered for the Graduate Prize.
Please submit extended abstracts of between 750 and 1,000 words to philosophicalbioethics@gmail.com by 11:59 pm EST on Friday, January 24, 2020. Abstracts should be formatted for blind review and should be suitable for presentation in 30-35 minutes. Notification of acceptance will take place via email by Friday, February 14, 2020.
When submitting your abstract, please also indicate whether you would be interested in serving as a commentator in the event that your abstract is not selected for presentation. We will be inviting four additional participants to serve as commentators.
