With the claim that “belief aims at truth,” philosophers designate a specific feature of belief according to which believing a proposition carries with it some sort of commitment or teleological directedness toward the truth of the believed proposition. The hypothesis that beliefs involve an aim at truth has been used by philosophers to explain a number of features specific to this type of mental state, such as the impossibility of believing at will, the absurdity of asserting Moorean sentences (e.g., “I believe that it is raining, but it is not raining”), and the normative dimension of evidential considerations in the processes of belief-formation. Many consider aiming at truth constitutive of belief, individuating belief as that type of mental state and distinguishing beliefs from other mental attitudes. In the contemporary debate there is disagreement over how to interpret the claim that belief aims at truth. Different accounts of the aim have been suggested in normative, teleological, and minimalist terms. Some philosophers even deny that beliefs involve an aim in any interesting sense. A view that has recently gained popularity is that beliefs do not aim at mere truth, but at knowledge. Although the two issues may be related, questions about the aim of belief must be distinguished from questions concerning whether having true beliefs is valuable, and whether truth is the ultimate goal of inquiry.
