Pietro Cibinel (Jesus College): Parity and Neighbourhoods of Value
Ruth Chang has argued that items in so-called hard cases are “on a par”, where parity is understood as a fourth positive value relation of comparability beyond “better than”, “worse than”, and “as good as”. Central to Chang’s argument for parity is the notion of neighbourhoods of value. In this talk, I explore different proposals about how to characterise neighbourhoods of value on Chang’s behalf, and present problems for each. I briefly conclude by noting that some other theories about hard cases face similar problems as Chang’s, while others do not.
