초록

마틴뢰프의 직관주의적 유형론의 중요 사항들을 설명하고, 그 체계의 가장 중요한 특성 중의 하나인 명제와 판단의 구분에 관해 검토한다. 1절에서 문제를 도입한 후, 2절에서 직관주의적 유형론의 명제개념은 직관주의적 명제개념의 발전된 형태임을 보이고, 3절에서는 직관주의적 유형론에서 가장 기본적인 판단개념을 설명한 후, 4절에서 직관주의적 유형론의 기본적인 추론규칙들을 설명하고 그 적용의 한 사례를 검토할 것이다. 마지막으로 5절에서, 직관주의적 유형론에서 명제와 판단의 구분이 차지하는 중요성을 부연한 후, 기초론적 체계에서 명제와 판단의 구분이 필수적인지의 문제와 관련하여, 통상적인 프레게적 구분으로부터 시작하여 직관주의적 유형론에서와 같은 구분에 이르기 위해서는 어떤 것들이 전제되거나 정당화되어야 하는지 검토할 것이다.

Abstract

We explain some basic elements of Martin-Löf's type theory and examine the distinction between propositions and judgments. In section 1, we introduce the problem. In section 2, we explain the concept of proposition in the intuitionistic type theory as a development of the intuitionistic conception of proposition. In section 3, we explain the concept of judgment in the intuitionistic type theory. In section 4, we explain some basic inference rules and examine a particular derivation in the theory. In section 5, we examine one route from the Fregean distinction between propositions and judgments to the distinction between them in the intuitionistic type theory, paying attention to the alleged necessity for introducing different forms of judgments.
