Abstract

In his paper “Wellbeing and Changing Attitudes Across Time”, Krister Bykvist investigates the challenge that changing attitudes pose for attitude-sensitive theories of well-being in determining temporal wellbeing. He offers both a useful tool to investigate the conceptual space of possible answers, namely an attitudinal matrix, as well as a seemingly plausible constraint on such an answer, which he terms ‘diagonalism’. This paper draws on his matrix to provide an argument against diagonalism and offer an error theory regarding its intuitive force. Using his matrix, I sketch my own view of temporal well-being according to which it is not a single unified concept, but can rather be understood in two different ways (‘better for’ vs. ‘better off’), both of which are interesting in their own right.
