In this paper, I show how realist moral naturalists can provide an intra-theoretic explanation of the epistemic possibility of wholesale moral error. This is a requirement on metaethical theories that has been recently defended by Akhlaghi (2021). After clarifying Akhlaghi’s argument and responding to Evers’s (2021) recent rebuttal, I argue that even under the assumption that moral facts are grounded in an appropriate subset of natural facts (N-facts), there is still a non-zero probability of wholesale moral error. This is demonstrated (...) by considering three types of epistemically possible scenarios: specifically, it could either be that N-facts do not actually exist, or that N-facts exist in a way that entails wholesale moral error, or that N-facts exist in a non-error theoretic way, but their existence is temporally restricted.

Bird reveals an important problem at the heart of Armstrong’s theory of laws of nature: to explain how a law necessitates its corresponding regularity, Armstrong is committed to a vicious regress. In his very brief response, Armstrong gestures towards an argument that, as he admits, is more of a “speculation.” Later, Barker and Smart argue that a very similar problem threatens Bird’s dispositional monist theory of laws of nature and he is committed to a similar vicious regress. In this paper, (...) first, I construct Armstrong’s would-be argument in response to Bird. Second, I argue that his response makes his account of laws and natural properties incompatible with science. Finally, I argue that Armstrong’s strategy to address Bird’s criticism can be used, quite ironically, to defuse Barker and Smart’s argument against Bird. (shrink)

This paper examines some possibilities for the laws of nature changing over time. This is done within the context of recent literature on transformational emergence. Transformational emergence is a diachronic account of emergence that does not require the invariance of fundamental objects, properties, and laws. The requirement that no new laws are introduced after the first instance of the universe seems to indicate that all the laws of the universe are present from the outset. By using a dispositional approach to (...) fundamental properties, this restriction can be avoided. An argument appealing to quantitative laws of nature is then used to show that such laws are not, contrary to dispositional essentialism, metaphysically necessary. Further arguments are given to support the possibility of change of laws across time rather than across worlds and why the identity conditions for properties are different in the two cases. The paper is framed by an analysis of John Stuart Mill’s reasons for imposing the invariance requirement on fundamental laws. (shrink)
