Truthmaker Semantics for Relevant Logic (2020)
Journal Article

I develop and defend a truthmaker semantics for the relevant logic R. The approach begins with a simple philosophical idea and develops it in various directions, so as to build a technically adequate relevant semantics. The central philosophical idea...

Impossible Worlds (2019)
Book

The latter half of the twentieth century witnessed an ‘intensional revolution’, a great collective effort to analyse notions which are absolutely fundamental to our understanding of the world and of ourselves—from meaning and information to knowledge... Read More about Impossible Worlds.

Logic for exact entailment (2019)
Journal Article

An exact truthmaker for A is a state which, as well as guaranteeing A's truth, is wholly relevant to it. States with parts irrelevant to whether A is true do not count as exact truthmakers for A. Giving semantics in this way produces a very unusual c... Read More about Logic for exact entailment.

Knowing how things might have been (2018)
Journal Article

I know that I could have been where you are right now and that you could have been where I am right now, but that neither of us could have been turnips or natural numbers. This knowledge of metaphysical modality stands in need of explanation. I will... Read More about Knowing how things might have been.

From nature to grounding (2018)
Book Chapter

Grounding is a powerful metaphysical concept; yet there is widespread scepticism about the intelligibility of the notion. In this paper, I propose an account of an entity’s nature or essence, which I then use to provide grounding conditions for that... Read More about From nature to grounding.

Essential bundle theory and modality (2018)
Journal Article

Bundle theories identify material objects with bundles of properties. On the traditional approach, these are the properties possessed by that material object. That view faces a deep problem: it seems to say that all of an object’s properties are esse... Read More about Essential bundle theory and modality.

What Truth Is (2018)
Book

© Mark Jago 2018. What Truth Is presents and defends a novel theory of what truth is, in terms of the metaphysical notion of truthmaking. This is the relation which holds between a truth and some entity in the world, in virtue of which that truth is... Read More about What Truth Is.

Material Objects and Essential Bundle Theory (2017)
Journal Article

In this paper we present a new metaphysical theory of material objects. On our theory, objects are bundles of property instances, where those properties give the nature or essence of that object. We call the theory essential bundle theory. Property p... Read More about Material Objects and Essential Bundle Theory.

Material objects and essential bundle theory (2017)
Journal Article

In this paper we present a new metaphysical theory of material objects. On our theory, objects are bundles of property instances, where those properties give the nature or essence of that object. We call the theory essential bundle theory. Property p... Read More about Material objects and essential bundle theory.

Propositions as truthmaker conditions (2017)
Journal Article

Propositions are often aligned with truth-conditions. The view is mistaken, since propositions discriminate where truth conditions do not. Propositions are hyperintensional: they are sensitive to necessarily equivalent differences. I investigate an a... Read More about Propositions as truthmaker conditions.

Modal realism, still at your convenience (2017)
Journal Article

Divers (2014) presents a set of de re modal truths which, he claims, are inconvenient for Lewisean modal realism. We argue that there is no inconvenience for Lewis.

Advanced modalizing problems (2016)
Journal Article

I present an internal problem for David Lewis’s genuine modal realism. My aim is to show that his analysis of modality is inconsistent with his metaphysics. I consider several ways of modifying the Lewisian analysis of modality, but argue that none a... Read More about Advanced modalizing problems.

Alethic undecidability doesn’t solve the Liar (2016)
Journal Article

Stephen Barker (2014) presents a novel approach to solving semantic paradoxes, including the Liar and its variants and Curry’s paradox. His approach is based around the concept of alethic undecidability. His approach, if successful, renders futile al... Read More about Alethic undecidability doesn’t solve the Liar.

Impossible Worlds (2013)
Journal Article

© 2013 The Author(s). NOÛS published by Wiley Periodicals, Inc. Impossible worlds are representations of impossible things and impossible happenings. They earn their keep in a semantic or metaphysical theory if they do the right theoretical work for... Read More about Impossible Worlds.

Journal Article

Imagine the possibilities: information without overload
Journal Article

Information is often modelled as a set of relevant possibilities, treated as logically possible worlds. However, this has the unintuitive consequence that the logical consequences of an agent's information cannot be informative for that agent. There...

Rule-based and Resource-bounded: A New Look at Epistemic Logic
Conference Proceeding

Syntactic logics do not suffer from the problems of logical omniscience but are often thought to lack interesting properties relating to epistemic notions. By focusing on the case of rule-based agents, I develop a framework for modelling resource-bou... Read More about Rule-based and Resource-bounded: A New Look at Epistemic Logic.
