Requirements

1) Attendance: you are required to attend seminar meetings on Fridays.

2) Readings: for each week, there is a reading assignment. You are required to read the relevant material before each meeting, and come prepared to the seminar with at least one question for discussion; your question(s) should be submitted on the Piazza page of the course by Wednesday of each week. You should also bring the week’s reading material to the seminar meeting.

3) Participation: you are expected to be an active participant in the seminar meetings.

4) Writing: There is a summative essay assignment of 4,500 words for this course. You can write on a topic of your choice, provided it engages with the material we cover in this module, provided you agree an essay question with an instructor, who officially approves it. Please come to see either instructor to talk about your chosen topic prior to starting to work on it. Note: If you write on a non-agreed question, you will fail the course. Essays should be submitted on Moodle. There is no need to submit a paper copy.

5) Presentation of your own ideas at the mini-conference. You’ll present your work in progress and the rest of us will give you feedback on it.

Class 2. Epistemic Modals I

We will begin by introducing a different perspective on the way modal domains for modals of all kinds are constructed. Modal domains are projected from anchors that are selected by individual modal words and are entities that are part of the evaluation world. Modal domains may then be further constrained by lexical requirements of individual lexical items (like should or ought to), or by defeasible all-purpose assumptions about the normal course of events.

Class 5. Conditionals II – If p, then p!

Guest Speaker: Matt Mandelkern (Oxford, All Souls)

Abstract. The history of the conditional can be viewed as an attempt to find a theory which (i) does validate intuitive logical principles and (ii) does not make the conditional 'If p, then q' equivalent to the material conditional 'Not p or q'. This turns out to be a tricky task—so tricky, in fact, that it has led some to give up the game, arguing that conditionals are not in the terrain of truth-conditional meanings at all. In the first part of my talk, I will show that this job is even harder than we thought: there turns out to be a tension between the principle that 'If p, then p' is always true and the popular Import-Export principle, which says that we ''remember'' successive conditional antecedents in evaluating the consequent of the conditional. Indeed, I show that we cannot plausibly validate both principles without collapsing the conditional to the material conditional. As a result, many prominent theories of the conditional invalidate 'If p, then p'. I argue that this is a problem; after all, if p, then p! In the latter part of the talk, I will argue that this should not, however, lead us to despair of giving a truth-conditional theory of the conditional. I propose a route out of this impasse which depends on attention to logical differences between indicative conditionals (like 'If it rained, the picnic was cancelled') versus subjunctive conditionals (like 'If it had rained, the picnic would have been cancelled').

Class 6. The Psychological & Linguistic Representation of Modality

Guest Speaker: Jonathan Phillips (Harvard)

Room: G17 (ground floor), Institute for Advanced Studies (IAS), South Wing, UCL, Gower Street.

Abstract. This talk presents a new approach to connecting the growing body of work on the psychological representation of modality (the way humans construct and reason over sets of non-actual events) to work in linguistics/philosophy on the semantics of modals. The general capacity for modal cognition plays a critical role in a wide diversity of high-level cognition, e.g., causal reasoning, moral judgment, theory of mind, decision making, and so on. Critically, humans are able to engage in much of this high-level cognition quickly and effortlessly. I'll provide empirical evidence that these aspects of human cognition are drawing on general-purpose, default representations of what is possible in a given context. Importantly, this research also provides clear evidence that the set of events represented by default is highly constrained by both descriptive and prescriptive normality. After reviewing this work, I'll take up the question of how we might connect this picture of modality at a psychological level to the semantics we give for modals in natural language. I'll sketch a general approach from joint work with Angelika Kratzer and then end with a few new studies that provide provocative evidence that the domain of quantification even for epistemic modals is implicitly constrained by what we take to be the normal course of events rather than what is known or what is probable.

Class 7. Conditionals III – On the Semantics and Heuristics of Indicative Conditionals

Guest Speaker: Tim Williamson (Oxford, New College)

Room: G11 (ground floor), Institute for Advanced Studies (IAS), South Wing, UCL, Gower Street.

Abstract. The talk will discuss the heuristics humans use to assess indicative conditionals. The primary one is the Suppositional Rule: take the same attitude to the conditional as you take to its consequent on the supposition of its antecedent. The Rule explains the connection between credence in a conditional and credence in its consequent conditional on its antecedent. It also explains the pull of standard natural deduction rules for the conditional. However, the Rule is inconsistent, like various other heuristics. Its effect is also mitigated by the secondary heuristic of treating conditional testimony like other kinds of testimony, which does not accord with the Rule. I will explain how this total practice is best explained on the assumption that indicative conditionals have material truth-conditions.

Class 9. Degrees of Causation and Causatives

Guest Speaker: Alex Kaiserman (Oxford)

Should we model causatives in terms of counterfactuals? If not, how shall we analyse them? And can one give a unified account of causatives? And how to account for degrees of causation? These are the questions we’ll tackle this week.

The instructors will run this session together with the guest speaker.
