  1. 1. Mistaken morality? : an essay on moral error theory

    Sammanfattning : This dissertation explores arguments and questions related to moral error theory – the idea that morality inevitably involves a fundamental and serious error such that moral judgments and statements never come out true. It is suggested that the truth of error theory remains a non-negligible possibility, and that we for this reason should take a version of moral fictionalism seriously. LÄS MER

  3. 2. Efficient sampling of Bayesian posteriors and predictive distributions in χEFT

    Sammanfattning : In this thesis I employ Bayesian statistics to quantify parametric and epistemic uncertainties in chiral effective field theories (χEFT) and propagate these forward to predictions of observables in low-energy nuclear physics. Two primary sources of uncertainty---experimental errors and the theoretical error induced by the truncation of the EFT at up to next-to-next-to-leading-order---are modelled and accounted for in the posterior distributions of the unknown low-energy constants (LECs) that govern interaction strengths in χEFT.
