An encyclopedia entry which covers various revisionary conceptions of which macroscopic objects there are, and the puzzles and arguments that motivate these conceptions: sorites arguments, the argument from vagueness, the puzzles of material constitution, arguments against indeterminate identity, arguments from arbitrariness, debunking arguments, the overdetermination argument, and the problem of the many.

Certain contemporary Nietzsche scholars claim to have discovered Nietzsche’s position on metaethics through a careful reading and interpretation of his texts. Whose account is most accurate? Unfortunately, Nietzsche’s texts underdetermine his views on metaethics; we lack the textual evidence to settle these debates decisively. Does this mean that the historical Nietzsche’s metaethical beliefs, ultimately inaccessable, are of little use to contemporary metaethical study? Or instead, must metaethicists interested in Nietzsche fundamentally change how Nietzsche’s works are to be understood? While I (...) present scholars who argue that Nietzsche’s corpus as a whole should be understood in radically different ways, I ultimately argue that we can avoid both of the above questions if scholars working in the history of philosophy tradition pivot their focus from attempting to offer a descriptive account of Nietzsche’s metaethical view and instead embrace appropriation.
