negation
Significado: The denial, contradiction, or reversal of something. In logic, the operation that transforms a true proposition into a false one and vice versa.
Negation is fundamental to both logic and rhetoric. In propositional logic, negation is the simplest operation — 'not P' — and is represented by the symbol ¬. In philosophical and literary criticism, negation takes on richer connotations: Hegel's dialectic depends on negation as a creative force, and poststructuralists speak of the negation of meaning. In everyday formal writing, negation means the denial or nullification of something previously asserted or assumed. It collocates naturally with 'of' — the negation of hope, the negation of rights.
Ejemplos
- The verdict was widely seen as a negation of the principles of natural justice the court was supposed to uphold. 该判决被广泛视为是对法院本应维护的自然正义原则的否定。El veredicto fue ampliamente considerado como una negación de los principios de justicia natural que el tribunal debía defender.その評決は、裁判所が守るべき自然的正義の原則の否定と広く見なされた。그 판결은 법원이 수호해야 할 자연적 정의 원칙의 부정으로 널리 간주되었다.
- In classical logic, double negation — applying the 'not' operator twice — returns the original proposition. 在经典逻辑中,双重否定——两次使用'非'运算符——会得到原来的命题。En lógica clásica, la doble negación — aplicar el operador «no» dos veces — devuelve la proposición original.古典論理学において、二重否定——「非」演算子を二度適用すること——は元の命題に戻る。고전논리학에서 이중부정 — '아니다(not)' 연산자를 두 번 적용하는 것 — 은 원래의 명제로 되돌아간다.
- The philosopher argued that every act of creation contains within it a corresponding act of negation. 这位哲学家认为,每一个创造行为都包含着一个相应的否定行为。El filósofo argumentó que todo acto de creación contiene en sí mismo un acto correspondiente de negación.その哲学者は、あらゆる創造行為にはそれに対応する否定行為が内在すると論じた。그 철학자는 모든 창조 행위에는 그에 상응하는 부정 행위가 내재한다고 주장했다.
