We believe the error theory.

Bart Streumer thinks that we cannot believe the global normative error theory. Streumer's argument presupposes a Cartesian theory of belief fixation. The Cartesian theory entails that we can understand a proposition without believing it. But the Cartesian theory of belief fixation is false, and the Spinozan theory is true. The Spinozan theory of belief fixation entails that we cannot understand a proposition without believing it. The present paper argues that Streumer's claim is false, and we can believe the global normative error theory because the Spinozan theory is correct. The paper then applies the Spinozan theory of belief fixation to the "Now what?" problem for global normative error theory and responds to objections. [ABSTRACT FROM AUTHOR]
