Indiscernibles

“Indiscernibles, general covariance, and other symmetries.”

Structural Realism Ladyman, James 2009

Its interest lies in the fact that on this view it would seem that the Principle of the Identity of Indiscernibles (PII), restricted so that identity involving properties are not in its scope, must be true.

Structural Realism Ladyman, James 2009

In other words, the Principle of the Identity of Indiscernibles (PII) follows from this conception of the nature of substance, and PII entails that, for any possible world, there is at most one instance of a CIC.

This is indeed an important consequence of his Principle of the Identity of Indiscernibles.

Leibniz's Modal Metaphysics Look, Brandon C. 2008

The Identity of Indiscernibles, says that if two things share all of their properties then they are identical, i.e., the same thing.

Note that throughout this entry, the following standard abbreviations are used: PC (Principle of Contradiction), PSR (Principle of Suffficient Reason), PII (Principle of the Identity of Indiscernibles), PIN (Predicate-in-Notion Principle), and CIC

Gottfried Wilhelm Leibniz Look, Brandon C. 2007

But, second, and rarely remarked upon, Leibniz holds that the view that our minds are blank slates at birth violates the Principle of the Identity of Indiscernibles.

Gottfried Wilhelm Leibniz Look, Brandon C. 2007

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

The Identity of Indiscernibles Forrest, Peter 2006

This has immediate implications for Leibniz's Principle of the Identity of Indiscernibles which, expressed crudely, insists that two things which are indiscernible, must be, in fact, identical.

Let us consider, first, Leibniz's famous Principle of the Identity of Indiscernibles in the context of the particles-as-individuals package.
