This book offers a comprehensive philosophical investigation of ignorance. Using a set of cognitive tools and models, it discusses features that can describe a state of ignorance if linked to a particular type of cognition affecting the agent's social behavior, belief system, and inferential capacity. The author defines ignorance as a cognitive condition that can be either passively (and unconsciously) borne by an agent or actively nurtured by him or her, and a condition that entails epistemic limitations (which can be any lack of knowledge, belief, information or data) that affect the agent's behavior, belief system, and inferential capacity. The author subsequently describes the ephemeral nature of ignorance, its tenacity in the development of human inferential and cognitive performance, and the possibility of sharing ignorance among human agents within the social dimension. By combining previous frameworks such as the naturalization of logic, the eco-cognitive perspective in philosophy and concepts from Peircean epistemology, and adding original ideas derived from the author's own research and reflections, the book develops a new cognitive framework to help understand the nature of ignorance and its influence on the human condition.

This book offers a new and externalist perspective in ignorance studies. Agnotology, the epistemology of ignorance, and, more generally, ignorance studies have grown to cover and explore different phenomena and subjects of research, from known events in history and sociology of science to the investigation of ordinary reasoning and cognitive processing. Nonetheless, although interested scholars have discussed ignorance phenomena and their impact on cognition, most of them have only adopted an internalist perspective to approach this theme. Meanwhile, even though externalist perspectives on cognition flourished in recent literature, authors have paid little attention to the emerging field of ignorance studies. Ignorance has been generally left out from the inquiries on the extension of cognitive states, cognitive processes, and predictive reasoning. Thus, in this volume, we seek to merge the two growing areas of research and to fill this research gap fruitfully. By addressing the uncomfortable themes that pertain to ignorance and related phenomena through an externalist perspective, this book aims to provide much food for thoughts to cognitive scientists and philosophers alike, enriching the current range and reach of both ignorance studies and externalist approaches to cognition.
