My aim in this paper is to present and discuss a novel understanding of the nature of epistemic vice. I highlight that epistemic vice such as excessive curiosity, gossip and excessive inquisitiveness do not obstruct the acquisition, transmission and retention of knowledge and are not characterized by a deficiency of epistemic desires or vicious epistemic motivations. However, I argue that such traits ought to be classified as epistemic vices because the agent who possesses them causes epistemic harm to other agents (...) through those traits’ characteristic activities.To remedy obstructivism’s inability to account for vices that cause epistemic harm in other ways besides blocking effective epistemic inquiry, I propose an amended version of this theory. I argue that epistemic vices are character traits, attitudes, and ways of thinking that obstruct the acquisition, transmission, and retention of knowledge and/or cause other kinds of epistemic harm. In addition, I propose a modified version of motivationalism that cashes out non-obstructing, excess-motivation vices in terms of motivation simply by acknowledging, and incorporating into theory, excessive epistemic drives and the negative epistemic (and non-epistemic) consequences stemming from them.
