Abstract

Phenomenal Contrast Arguments (PCAs) are a prominent method in philosophy of mind for, among other uses, investigating how specific mental features shape the phenomenal character of experience. This paper identifies a general and underexplored obstacle to the success of PCAs: The necessity of demonstrating that the contrasts employed in these arguments are genuinely phenomenal, rather than merely cognitive or otherwise non-phenomenal. We contend that proponents of PCAs often assume a phenomenal difference without adequately ruling out these alternative explanations for the available contrast. While we do not preclude the possibility of successful PCAs, our arguments suggest that many existing instances fail to meet this burden.
