identicalité

Identité refers to the state of being identical. In philosophy, identity is a complex concept that explores what makes something itself and distinct from other things. It can refer to numerical identity, meaning two things are the same single entity, or qualitative identity, where two things share the same properties but are still distinct entities. The question of personal identity, for instance, asks what makes a person the same person over time, despite changes in their physical body or mental states.

In mathematics, identicalité is represented by the equality symbol (=). Two mathematical expressions are identical if they represent the same value or object. For example, 2+2 = 4 signifies that the expression "2+2" and the number "4" are numerically identical.

In everyday language, identicalité is used to describe things that are exactly the same. This can apply to objects, such as identical twins who share the same genetic makeup, or to situations where events or outcomes are precisely alike. The concept highlights sameness, lack of distinction, and perfect correspondence. The criteria for establishing identicalité can vary depending on the context, ranging from subjective perception to rigorous objective measurement.
