Dissertation, Oxford (2015)
The topic of this thesis is axiological uncertainty – the question of how you
should evaluate your options if you are uncertain about which axiology is
true. As an answer, I defend Expected Value Maximisation (EVM), the
view that one option is better than another if and only if it has the greater
expected value across axiologies. More precisely, I explore the axiomatic
foundations of this view. I employ results from state-dependent utility theory, extend them in various ways and interpret them accordingly, and thus provide axiomatisations of EVM as a theory of axiological uncertainty.
