What is the principle of indiscernibles?

What is the principle of indiscernibles?

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.

What does Leibniz’s law tell us?

It states that no two distinct things exactly resemble each other. This is often referred to as ‘Leibniz’s Law’ and is typically understood to mean that no two objects have exactly the same properties.

What is the principle of the non identity of indiscernibles?

More formally, the principle states that if x is not identical to y, then there is some property P such that P holds of x and does not hold of y, or that P holds of y and does not hold of x.

What is diachronic identity?

By diachronic identity we mean an identity holding between something existing at one time and something existing at another. One question is whether synchronic and diachronic identity are different kinds of identity. Some philosophers are willing to countenance different kinds of identity.

What is mind according to identity?

The identity theory of mind holds that states and processes of the mind are identical to states and processes of the brain. The identity theory of mind is to the effect that these experiences just are brain processes, not merely correlated with brain processes.

What is qualitative identity?

qualitative identity in British English noun. logic. the relation that holds between two relata that have properties in common. This term is used to distinguish many uses of the words identical or same in ordinary language from strict identity or numerical identity.

How is identity formed?

Identity is formed through a process of exploring options or choices and committing to an option based upon the outcome of their exploration. Failure to establish a well-developed sense of identity can result in identity confusion.

What is identity theory?

Identity theory, in philosophy, one view of modern Materialism that asserts that mind and matter, however capable of being logically distinguished, are in actuality but different expressions of a single reality that is material.

Does identity change over time?

A person’s identity is thus continuous over time, in the sense that the different moments that constitute this person’s life are sufficiently connected in order to attribute them to one and the same person (or “self”) even though the person is changing.

What is the difference between qualitative and numerical identity?

A distinction is customarily drawn between qualitative and numerical identity or sameness. Things with qualitative identity share properties, so things can be more or less qualitatively identical. Numerical identity requires absolute, or total, qualitative identity, and can only hold between a thing and itself.

Is mind same as brain?

The brain is an organ but the mind isn’t. The brain is the physical place where the mind resides. The mind is the manifestations of thought, perception, emotion, determination, memory and imagination that takes place within the brain. Mind is often used to refer especially to the thought processes of reason.

How is the identity of indiscernibles formulated?

The Identity of Indiscernibles (hereafter called the Principle) is usually formulated as follows: if, for every property F, object x has F if and only if object y has F, then x is identical to y. Or in the notation of symbolic logic: ∀ F (Fx ↔ Fy) → x = y.

Which is the best definition of the word indiscernible?

Definition of indiscernible : incapable of being discerned : not recognizable as distinct Examples of indiscernible in a Sentence Hidden under vines and moss, the crumbling wall was almost indiscernible. a change made for indiscernible reasons

Why are indiscernibles of an object of interest?

This is often referred to as ‘Leibniz’s Law’ and is typically understood to mean that no two objects have exactly the same properties. The Identity of Indiscernibles is of interest because it raises questions about the factors which individuate qualitatively identical objects.

How is the converse principle related to the identity of indiscernibles?

While some think that Leibniz’s version of the principle is meant to be only the indiscernibility of identicals, others have interpreted it as the conjunction of the identity of indiscernibles and the indiscernibility of identicals (the converse principle).
