We present a substructural epistemic logic, based on Boolean BI, in which the epistemic modalities are parametrized on agents’ local resources. The new modalities can be seen as generalizations of the usual epistemic modalities. The logic combines Boolean BI’s resource semantics with epistemic agency. We give a labelled tableaux calculus and establish soundness and completeness with respect to ...

This essay aims to redress the contention that epistemic possibility cannot be a guide to the principles of modal metaphysics. I argue that the interaction between the multi-dimensional intensional framework and intensional plural quantification enables epistemic possibilities to target the haecceitistic properties of individuals. I outline the elements of plural logic, and I specify, then, a m...

Standard epistemology takes it for granted that there is a special kind of value: epistemic value. This claim does not seem to sit well with act utilitarianism, however, since it holds that only welfare is of real value. I first develop a particularly utilitarian sense of “epistemic value”, according to which it is closely analogous to the nature of financial value. I then demonstrate the promi...

This paper describes the process of theory building in performance measurement in facilities management through a study of the applications of some core principles of business performance context, and theory verification as it investigates the practical validity of a number of existing general theoretical propositions relating to business performance measurement in facilities management. In thi...

Epistemic uncertainties appear widely in civil engineering practice. There is a clear consensus that these epistemic uncertainties need to be taken into account for a realistic assessment of the performance and reliability of our structures and systems. However, there is no clearly defined procedure to meet this challenge. In this paper we discuss the phenomena that involve epistemic uncertaint...

The paper addresses two fundamental issues in epistemic axiology. It argues primarily that curiosity, in particular its intrinsic variety, is the foundational epistemic virtue since it is the value-bestowing epistemic virtue. A response-dependentist framework is proposed, according to which a cognitive state is epistemically valuable if a normally or ideally curious or inquisitive cognizer woul...

Symmetries in physics are a guide to reality. That much is well known. But what is less well known is why symmetry is a guide to reality. What justifies inferences that draw conclusions about reality from premises about symmetries? I argue that answering this question reveals that symmetry is an epistemic notion twice over. First, these inferences must proceed via epistemic lemmas: premises abo...
