Logical closure refers to the property of a set of propositions being closed under logical consequence, meaning if the propositions are true, then all propositions that logically follow from them are also true. This concept is fundamental in understanding the completeness and consistency of logical systems, ensuring that all derivable truths are accounted for within a given framework.

Logical consequence is a fundamental concept in logic that describes the relationship between premises and conclusion, where if the premises are true, the conclusion must also be true. It is central to understanding the validity of arguments and is used to determine whether a set of statements logically entails another statement.

Completeness in various contexts refers to the extent to which a system, theory, or dataset encompasses all necessary components or information to be considered whole and functional. It is a crucial criterion in fields like mathematics, logic, and data science, where it ensures that no essential elements are missing, thereby enabling accurate analysis, decision-making, and problem-solving.

completeness

Consistency refers to the steadfast adherence to the same principles or course of action over time, which fosters reliability and trust. It is essential in various fields, from personal habits to business practices, as it creates predictability and stability, allowing for the measurement of progress and effectiveness.

consistency

Logical frameworks are formal systems used to define or analyze the syntax and semantics of logical languages, often employed in computer science for specifying and verifying properties of software and systems. They provide a structured way to represent knowledge and reason about it, enabling the development of sound and consistent formal proofs.
