In her influential article published in 2016, Alexandra Walsham, Professor of Modern History at the University of Cambridge, coined the metaphor that ‘Archives are the factories and laboratories of the historian’. Traditionally viewed as neutral storehouses of official records passively awaiting historians’ scrutiny, conceptions of archives have expanded in recent decades. Archives are now understood as complex social and cultural entities that actively participate in shaping understandings of the past. This paper examines shifting perspectives on the nature and functions of archives through a critical analysis of key debates. Specifically, this paper adopts a hermeneutic lens to critically engage Walsham’s metaphor and move beyond its potential limitations through situated analysis and interpretation. This paper explores how archives are actively implicated in knowledge construction through their contents, organisational frameworks, and interactions with historians. Recognising archives as fragmented, culturally contingent remnants that mediate engagement with the past, the paper calls for collaborative, reflective approaches between archivists and historians. The paper also acknowledges historians’ subjective interpretive roles while advocating consultation of archivists’ contextual expertise. Ultimately, it advances methodological discussions on writing history through a nuanced appreciation of archives as dynamic mediators within historical research, not transparent conduits neutrally supplying facts.

Differences among scientific, mathematical, and ethical subject matters motivate a pluralism where distinct domains of subject matter are associated with distinct truth properties and logics. However, it is unclear how such pluralism might accommodate potentially attractive epistemic norms, such as that one ought to believe only what is true, and that one ought to believe what is logically true. In this paper, I show how such pluralism can accommodate such norms by supplementing the account developed in Yu (2017a,b) with epistemic, doxastic, and deontic operators. The upshot is that pluralism is compatible with, even if not committed to, monism about epistemic norms.

This thesis comprises three main chapters—each comprising one relatively standalone paper. The unifying theme is fragmentalism about truth, which is the view that the predicate “true” either expresses distinct concepts or expresses distinct properties. In Chapter 1, I provide a formal development of alethic pluralism. Pluralism is the view that there are distinct truth properties associated with distinct domains of subject matter, where a truth property satisfies certain truth-characterizing principles. On behalf of pluralists, I propose an account of logic and semantics that shows how they can answer central conceptual and logical challenges for their view. In Chapter 2, I motivate and develop a modal account of propositions on the basis of an iterative conception of propositions, where the modality is logico-mathematical. The modal account of propositions takes the conception to motivate an inherently potential hierarchy of propositions. I show that the account helps provide satisfying solutions to the intensional paradoxes of Russell-Myhill, Kaplan, and Prior. In Chapter 3, I propose that “true” is polysemous. I suggest that “true” is initially polysemous between correspondence truth and disquotational truth, and further polysemous between the meanings corresponding to the subconcepts of the concept truth generated by the indefinite extensibility of that concept. I show that the proposal provides satisfying solutions to the semantic paradoxes.

There have been few attempts to answer the twin challenges for alethic pluralists to maintain standard accounts of the logical operators and of logical consequence in a sufficiently systematic and precise way. In this paper, I propose an account of logic and semantics on behalf of pluralists that answers both challenges in a sufficiently systematic and precise way. Crucially, the account accommodates mixed atomics, and its first-order extension also accommodates quantified sentences. Accordingly, pluralists can answer all the distinctively logical challenges for their view.
