If they were the same thing they would have the same properties.Leibnitz – principle of the indiscernibility of identicals = two substances if identical share the same properties.The mind does not have any parts and cannot be divided whereas the body does have parts (e.g. …

What is the principle of indiscernibility of identicals?

The principle of indiscernibility of identicals is uncontroversial and states that if two entities are identical with each other then they have the same properties.

How do you find the identity of indiscernibles?

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.

What does Leibniz mean by identity of indiscernibles?

The Identity of Indiscernibles. 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.

Is the identity of indiscernibles applicable in the quantum domain?

The Identity of Indiscernibles is of interest because it raises questions about the factors which individuate qualitatively identical objects. Recent work on the interpretation of quantum mechanics suggests that the applicability of the principle in the quantum domain is controversial (see French 2019).

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. It states that no two distinct things can be exactly alike, but this is intended as a metaphysical principle …
