Semantics and Pragmatics episodes
Our conversations may not always behave entirely logically, but we still have rules to follow. In this episode, we talk about the Cooperative Principle and the different Conversational Maxims that give us the rails our interactions run down.
Why do people interpret the same sentence multiple ways? What is it about semantics that leads us to more than one meaning? We take on semantic scope, and talk about how the most innocent-seeming words in your sentence are fighting it out to bestow upon you an interpretation where they come out on top.
How do we puzzle out what meanings lie beyond our sentences? What different flavours of extra meanings are there? In this episode, we talk about implicatures, entailments, and presuppositions: how to define them, what the differences are between them, and how they enrich our understanding of the world.
How much does logic structure our sentences, and what kind of logic should we use? In this episode, we talk about sentential logic: where it came from, how we connect things up systematically, and in what ways language looks like it moves away from pure logic.
What kind of logic can we find inside sentences? How do we calculate the meaning from what we hear? In this episode, we talk about predicate logic: why we need it, how it differs from sentential logic, and how we can combine it with quantifiers to capture the full meaning of our language.
How do we form sets of different elements? How do those collections contribute to meaning? In this episode, we talk about set theory: the basics of how it works, how it connects to adjectives, and how it informs the way we build up larger meanings from individual words.
How do we work with the people we're talking with to make conversation flow smoothly? What tools can we use to show we're engaged? In this episode, we talk about common ground: how we build it, whether it differs for face-to-face vs. online communications, and how memes and new turns of phrase can help conversations and communities along.
How can we tell what's relevant when we try to work out what other people mean? What can experiments tell us about how much we'll consider when puzzling out meaning? In this episode, we talk about relevance theory: how it can help us more scientifically approach relevance in our discussions, how it interacts with the rest of our understanding of the rules of conversations, and how we can play with relevance in experiments to make people more or less likely to behave in logical ways.
How can we tell what words like "few" and "many" do in our sentences? What's the right way to represent these words in our minds? In this episode, we talk about generalized quantifier theory: what the math for quantifiers should look like, what properties natural language quantifiers seem to all share, and what that means for how kids can learn them.
How can we capture the meanings of transitive sentences? How do we match our syntax trees to our semantics? In this episode, we talk about lambda calculus: why we need it to explain what our other semantic machinery can't, how to work out its math, and what it can show us about how words move around in sentences.
Why can't we just use "ever" or "at all" in any sentence we want? What do we have to change about how a sentence works to let words like those in? In this episode, we talk about negative polarity items, or NPIs: when they can show up, why their name is misleading, and how changing what a sentence entails changes everything for these little terms.
How do we focus on crucial information in our conversations? What methods do we have for moving things into the center of discussion? In this episode, we talk about information structure: how we build up the common ground in discussion, what we do to bring up topics and signal our focus, and how different languages use varying strategies to bring new ideas to the fore.
How do we combine words to build full propositions? How do we account for what people believe, not just what's definitely true? In this episode, we talk about type theory: how we can define terms by how they relate to the world and each other, what the difference is between sense and reference, and how we can use possible worlds to work out what people believe.
