The law of identity can be expressed as (=), where x is a variable ranging over the domain of all individuals. In logic, there are various different ways identity can be handled. In first-order logic with identity, identity is treated as a logical constant and its axioms are part of the logic itself. Under this convention, the law of identity ...
In Hegel's words, "Identity is the identity of identity and non-identity." More recent metaphysicians have discussed trans-world identity—the notion that there can be the same object in different possible worlds. An alternative to trans-world identity is the counterpart relation in counterpart theory. It is a similarity relation that rejects ...
The identity of indiscernibles is an ontological principle that states that there cannot be separate objects or entities that have all their properties in common. That is, entities x and y are identical if every predicate possessed by x is also possessed by y and vice versa.
The schoolman, in the fourth book of his Commentary of Aristotle's Metaphysics – a commentary which is full of the most ingenious and original views, – not only asserts to the law of Identity a coordinate dignity with the law of Contradiction, but, against Aristotle, he maintains that the principle of Identity, and not the principle of ...
In modal logic, the necessity of identity is the thesis that for every object x and object y, if x and y are the same object, it is necessary that x and y are the same object. [1] The thesis is best known for its association with Saul Kripke , who published it in 1971, [ 2 ] although it was first derived by the logician Ruth Barcan Marcus in ...
Identity is the set of qualities, beliefs, personality traits, appearance, or expressions that characterize a person or a group. [1] [2] [3] [4]Identity emerges during childhood as children start to comprehend their self-concept, and it remains a consistent aspect throughout different stages of life.
The principle of individuation is a criterion that individuates or numerically distinguishes the members of the kind for which it is given, that is by which we can supposedly determine, regarding any kind of thing, when we have more than one of them or not. [1] It is also known as a 'criterion of identity' or 'indiscernibility principle'.
Identity standard defines what it means to be who one is in a situation. The identity standard stores the self-meanings tied to social roles and membership in groups. This is the set of meanings for a given identity. The meanings in identity standard represent the goals or the way the situation is supposed to be.
