Episode 23 picks up right where 22 left off: with Jon and Dave continuing last week’s discussion of conditional reasoning! Specifically, they ramp up the complexity and outline how to handle unusual language like “unless” statements and “either/or” constructions, make conditional chains and spot the inferences they provide, tackle scenarios with multiple sufficient and necessary elements, and even master the elusive double-arrow. This is conditionality at its highest level.
