Luis Rosa

I'm a philosophy lecturer at Washington University in St. Louis. Before coming here, I was an assistant professor at CONCEPT in the University of Cologne, where I earned my habilitation. 

My research deals with things that muddle the mind and get in the way of its search for knowledge. That includes uncertainty, insufficient evidence, ambiguity, doubts concerning our cognitive powers, disagreement, indeterminacy, incoherence, paradoxes, defective questions, situations that call for suspension of judgment. The path of an inquirer is obscured by such elements, and that's a strong motivation I have for studying them.

I also investigate the logic and semantics of normative claims (involving deontic modals such as 'ought' and 'can') and ascriptions of attitudes (involving verbs such as 'think', 'doubt' and 'want'). These two types of sentence behave in mysterious but similar ways.
