intensional

Thân thiện

A dictionary entry defines a word by its intensional meaning.

Definition

1. Adjective:
   • Relating to the inherent meaning or attributes of a concept: "Intensional" describes the set of essential properties or attributes that define what something is, as opposed to its external references or extensions.
   • Pertaining to the internal content of a term: In logic and philosophy, "intensional" refers to the meaning or sense of a word or expression, focusing on its conceptual content rather than the actual objects it may denote.

Usage Examples

• Adjective:
  • The philosopher discussed the intensional definition of "bachelor" as an unmarried man. (The discussion focused on the inherent attributes that define the concept.)
  • In semantic analysis, we must consider both the extensional and the intensional aspects of a term. (The analysis must look at both the objects referred to and the term's inherent meaning.)

Advanced Usage

• "Intensional context": A linguistic or logical context where the truth of a statement depends on the meanings (intensions) of the terms used, not just their referents. Substitution of co-referential terms may not preserve truth.
  • Belief statements create an intensional context; "Lois Lane believes Superman can fly" does not imply she believes Clark Kent can fly, even though they are the same person.
• "Intensional logic": A system of formal logic that deals with the meanings of expressions, often incorporating concepts like necessity, possibility, and belief.
  • The development of intensional logic was crucial for analyzing statements about knowledge and belief.

Variants and Related Words
