The Indiscerniblity of Identicals is the principle that if two objects are absolutely identical then they must be indistinguishable from one another with respect to all of their properties. But does that include the context of the identical objects? The notion of identical gives rise to many philosophical problems, including: 1. What does it mean for an object to be the same as itself? 2. If x and y are identical (are the same thing), must they always be identical? Are they necessarily identical? 3. What does it mean for an object to be the same, if it changes over time? (Is applet the same as applet+1?) 4. If an object's parts are entirely replaced over time, in what way is it the same?
