The systematic study of how logical frameworks operate, how they're constructed, how they relate to each other, and how they're used in different contexts. The Theory of Logical Frameworks argues that logic is not one thing but many—that different frameworks serve different purposes, that no single framework is adequate for all reasoning tasks. It examines the history of logical systems (how classical logic developed, why alternatives emerged), their mathematical properties (completeness, consistency, decidability), their philosophical implications (what they say about truth and reason), and their practical applications (where each framework works best). The theory is the foundation of logical pluralism, the recognition that there are many ways to reason validly.
Example: "He'd thought logic was universal—same rules for everyone, everywhere. The Theory of Logical Frameworks showed him otherwise: different frameworks for different domains, different rules for different purposes. Classical logic worked for mathematics; paraconsistent logic worked for contradictions; fuzzy logic worked for vagueness. None was the logic; all were tools."
