Intellectual Virtues and Vices

This chapter sets out the philosophical foundations of the proposed account of virtues and vices of intellectual self-appraisal. It explains the nature of intellectual vices in general by distinguishing between sensibilities, thinking styles, and character traits. Subsequently, it describes the specific features of the epistemic vices of self-appraisal. The chapter supplies an account of what makes epistemic vices vicious, and argues in favour of a motivational view. In the author’s view the vices of intellectual self-appraisal are impairments of epistemic agency caused by motivations, such as those of self-enhancement or impression management, that also bring other epistemically bad motives in their trail. Such motivations bias epistemic evaluations of one’s cognitive abilities, processes, and states. These appraisals, in turn, have widespread negative influences on agents’ epistemic conduct as a whole.
