This paper discusses the logical space of alternative conceptual engineering projects, with a specific focus on (1) the processes, (2) the targets and goals, and (3) the methods of such projects. We present an overview of how these three aspects interact in the contemporary literature and discuss those alternative projects that have yet to be explored based on our suggested typology. We show how choices about each element in a conceptual engineering project constrain the possibilities for the others, thereby giving (...) rise to distinct groupings of possible projects under the banner of conceptual engineering. We conclude with a critical reflection on the potential ethical issues that arise as a result of effectively putting conceptual engineering into practice. (shrink)

In this paper, I investigate the nature of the metaphysical possibility of disunified time. A possibility that I argue presents unique problems for those who adhere to a strict A-theory of time, particularly those A-theorists who propose a presentist view. The first part of the paper discusses various arguments against the coherence of the concept of disunified time. I attempt to discount each of these objections and show that disunified time is indeed a possible and consistent topology of time. Then, (...) I attempt to show that disunified time is a problem for a semantics based on the A-series since A-truthmakers are hard to come by in a universe of temporally disconnected time-series. Finally, I provide a novel argument showing that presentists should be particularly fearful of such a universe. (shrink)
