Understanding Intension: The Core Meaning of Concepts

What is Intension?

Intension refers to the inherent content or essential properties and meanings of a concept or term. It’s what defines the concept itself, regardless of the specific instances it might apply to.

Intension vs. Extension

It’s crucial to distinguish intension from extension. While intension is the definition or meaning, extension is the set of all things that the term applies to.

• Intension: The meaning, properties, definition.
• Extension: The objects, individuals, or instances.

Key Components of Intension

The intension of a concept typically includes its defining characteristics and criteria. For example, the intension of ‘dog’ includes properties like ‘mammal,’ ‘four-legged,’ ‘canine,’ and ‘domesticated.’

Understanding intension is vital for clear communication, logical reasoning, and building consistent knowledge systems. It ensures that when we use a term, we are referring to the same set of essential properties.

Deep Dive: Formalizing Intension

In logic and philosophy, intension can be formalized. For instance, a proposition’s intension can be seen as the condition that must be met for it to be true in any possible world.

• Linguistics: Understanding word meanings.
