What sorts of material objects are there? Many philosophers opt for surprising answers to this question that seem deeply at odds with how we ordinarily think about the material world. Some embrace radically eliminative views, on which there are far fewer objects than we ordinarily take there to be, while others go in for radically permissive views on which there are legions of extraordinary objects that somehow escape our notice, despite being highly visible and right before our eyes. In this book, Daniel Z. Korman defends our ordinary, intuitive judgments about which objects there are. The book responds to a wide variety of arguments that have driven people away from the intuitive view: arbitrariness arguments, debunking arguments, overdetermination arguments, arguments from vagueness and material constitution, and the problem of the many. It also criticizes attempts to show that permissive and eliminative views are, despite appearances, entirely compatible with our ordinary beliefs and intuitions.

One of the central questions of material-object metaphysics is which highly visible objects there are right before our eyes. Daniel Z. Korman defends a conservative view, according to which our ordinary, natural judgments about which objects there are are more or less correct. He begins with an overview of the arguments that have led people away from the conservative view, into revisionary views according to which there are far more objects than we ordinarily take there to be (permissivism) or far fewer (eliminativism). Korman criticizes a variety of compatibilist strategies, according to which these revisionary views are actually compatible with our ordinary beliefs, and responds to debunking arguments, according to which these beliefs are the products of arbitrary biological and cultural influences. He goes on to respond to objections that the conservative's verdicts about which objects that are and aren't are objectionably arbitrary, and to the argument from vagueness, which purports to show that the sort of restriction that conservatives want to impose on which composites there are is bound to give rise to vagueness about what exists, something that is ruled out by widely accepted theories of vagueness. Finally, Korman responds to the overdetermination argument, the argument from material constitution, and the problem of the many, all of which are meant to motivate eliminativism by showing that accepting ordinary objects commits one to one or another absurdity.
