This two-day conference will explore the notions of trust and uncertainty in linguistics and literary studies. Trust and certainty are crucial aspects of knowledge and its production, covering/in relation with a range of phenomena among which authority, authenticity, faith, evidence, manipulation, and falseness. Following the COVID-19 pandemic crisis, many of these aspects – information and misinformation, the role of the expert, conspiracy theories – have gained acute prominence. However, this conference will draw much wider circles, taking into account historical developments and diverse aesthetic approaches to these topics.
