conditionson

Conditionson is a theoretical construct used in philosophy of language and formal semantics to describe how the truth of a proposition depends on a network of contextual requirements. Unlike traditional truth conditions that aim to assign fixed truth values independent of context, a conditionson locates truth within a set of conditional constraints that may vary across situations, communities, or discourse frames.

In this framework, a proposition p is evaluated with respect to a set C of conditions, where each condition encodes a contextual factor such as time, place, speaker intention, background knowledge, or surrounding discourse. The proposition p is considered true in a given context only if all conditions in C are satisfied. Conditionson thus formalizes how context-shape affects truth, providing a compact way to model contextual dependence without prescribing a single universal standard of truth.

Etymologically, conditionson is a neologism used by a minority of theorists to contrast contextual requirements with static truth conditions. The term emphasizes that truth is not merely a property of a sentence in isolation but arises from an intertwined set of conditions active in a particular communication scenario.

Applications of the concept appear in semantic theory, pragmatics, and computational linguistics, where researchers model context-sensitive expressions such as indexicals, demonstratives, or presuppositions. Critics argue that the approach can be vague or overly complex, risking an unwieldy representation of context. Proponents contend that conditionson offers a useful, explicit way to handle how meaning shifts with audience, setting, and purpose.
