According to the guise of the good thesis, we desire things under the ‘guise of the good.’ Here I sympathetically articulate a generic formulation of the guise of the good thesis, and address a problem for the view, which I call the problem of partiality. The problem is, roughly, that our partial pro-attitudes–for example, our special concern for ourselves–do not correspond to what is absolutely good. I criticize three solutions to the problem, and propose an alternative strategy, on which partial pro-attitudes constitute a species of illusion.

It is often argued that belief is partly constituted by a norm of truth. Most recent discussions have assumed that the norm is deontic concerning what may or ought to be believed. I criticize two proposals, one canvassed by Krister Bykvist and Anandi Hattiangadi, and the other defended by Daniel Whiting. Instead, I argue in favour of an evaluative norm, according to which we would do well to believe the truth. I show that an evaluative norm fares better than its deontic competitors with respect to the demandingness of truth, the aim of truth, and epistemic blame.
