Example Sentences
- "One of the fundamental principles governing identity is that of substitutivity—or, as it might well be called, that of indiscernibility of identicals. It provides that, given a true statement of identity, one of its two terms may be substituted for the other in any true statement and the result will be true."
- "For example, Levinson claims that a Stamitz symphony containing a "Manheim rocket"—a novel device in Stamitz's day—is an exciting musical work, but a work written today with the same sound structure would be funny rather than exciting. Since the Stamitz symphony and the (hypothetical) contemporary sound-identical work differ in properties, it follows from the indiscernibility of identicals that they are distinct musical works."
