I defend a naive conception of material objects, according to which there are such things as stones, statues, cats and their tails, but no "strange fusions" of such things as my nose and the Eiffel Tower. Virtually everyone in the literature rejects the naive conception in favor of some revisionary theory of material objects. Eliminativists (e.g., Unger, van Inwagen, Merricks) deny that there are such things as statues and stones and, in some cases, cats as well. Universalists (e.g., Lewis, Rea, Sider) hold that for any objects you like--even my nose and the Eiffel Tower--there is a single object composed of those objects. These revisionary theories are manifestly counterintuitive, but there are powerful arguments for preferring them to the naive conception. The first part of the dissertation is devoted to showing how these arguments can be resisted. First, I assess the charge that, given the correctness of the naive conception, it would have been a miraculous stroke of luck for us to have hit upon the privileged conceptual scheme. Second, I examine the Lewis-Sider argument from vagueness for unrestricted mereological composition, Third, I show that the grounding problem for coincident modally discernible objects can be solved. Fourth, show that the causal exclusion argument as applied to ordinary objects can be resisted without either systematic overdetermination or epiphenomena. In the second part of the dissertation, I argue that the prima facie conflict between revisionary theories and our ordinary discourse, beliefs, and intuitions about material objects proves to be an insurmountable problem for those theories. First, I argue that existing attempts to reconcile revisionary theories of material objects with folk discourse are unsatisfactory, Second, I provide a perspicuous statement of the "challenge from folk belief" and argue that the standard strategies for meeting the challenge are unsatisfactory.

The main focus of this thesis is indeterminate identity and its relations to vague objects and to imprecise designation. Evans's argument concerning indeterminate-identity statements is often regarded as a proof that vague objects cannot exist. In chapter I I try to argue that the argument may be refuted by vague objects theorists. In chapter II I present various accounts of what indeterminate identity between objects may consist in and three different characteristics of it. I argue that there are objects whose identity is indeterminate and that such indeterminacy is ontic in the sense that it concerns individuation and spatio-temporal boundaries of objects. I also formulate the argument showing that (independently of Evans's argument) terms designating indeterminately identical objects cannot be precise designators. Chapter III is devoted to problems concerning vagueness and identity-over-time. The indeterminate answer to the questions concerning diachronic identity in puzzling cases can be regarded as the correct response by both endurantists and perdurantists. However, while for perdurantists the whole vagueness of persistence conditions is a conceptual matter, for endurantists it deserves the name of "ontic vagueness". Chapter IV focuses on questions concerning vagueness and identity-at-a-time. I offer a new solution to the problem of the many, according to which in each case in which the problem arises there is - contrary to appearances - only one (vague) object present. The problem arises because each such object has many precisifications, which nevertheless have no ontological significance. I also propose a new account of what it takes for an object to be vague. Chapter V deals with indeterminate identity in the domain of quanta. The first part investigates the various problems concerning identity and individuation of quantum particles, whereas the second part is devoted to analysis and critique of E. J. Lowe's example of alleged indeterminate identity-over-time between electrons.

Minimalism concerning truth is the view that that all there is to be said concerning truth is exhausted by a set of basic platitudes. In the first part of this thesis, I apply this methodology to the concept of knowledge. In so doing, I develop a model of inexact knowledge grounded in what I call minimal margin for error principles. From these basic principles, I derive the controversial result that epistemological internalism and internalism with respect to self-knowledge are untenable doctrines. In the second part of this thesis, I develop a minimal theory of vagueness in which a rigorous but neutral definition of vagueness is shown to be possible. Three dimensions of vagueness are distinguished and a proof is given showing how two of these dimensions are equivalent facets of the same phenomenon. From the axioms of this minimal theory one can also show that there must be higher-order vagueness, contrary to what some have argued. In the final part of this thesis, I return to issues concerning the credentials of truth-minimalism. Is truth-minimalism compatible with the possibility of truth-value gaps? Is it right to say that truth-minimalism is crippled by the liar paradox? With respect to the former question, I develop a novel three-valued logical system which is both proof-theoretically and truth-theoretic ally well-motivated and compatible with at least one form of minimalism. With respect to the second question, a new solution to the liar paradox is developed based on the claim that while the liar sentence is meaningful, it is improper to even suppose that this sentence has a truth-status. On that basis, one can block the paradox by restricting the Rule of Assumptions in Gentzen-style presentations of the sentential sequent calculus. The first lesson of the liar paradox is that not all assumptions are for free. The second lesson of the liar is that, contrary to what has been alleged by many, minimalism concerning truth is far better placed than its rival theories to solve the paradox.
