Summary

In this lecture, Luis Rosa explores the epistemic virtues of suspending judgment, a state of neutrality towards a proposition. He begins by contrasting suspension with belief and disbelief, and introduces the framework of decision theory, where rational action is based on expected utility. He argues that suspension of judgment plays a crucial functional role in rational action: it can prevent risky decisions when evidence is insufficient, and it motivates further investigation to resolve uncertainty. Rosa distinguishes between cases where suspension is rational due to lack of evidence and cases where evidence actually entails a proposition but the agent fails to see the implication due to cognitive limitations. In the latter, suspension is not merely a passive state but an active step towards re-evaluating evidence and performing inferences. He illustrates this with a logical reasoning task, showing that suspension can be a necessary step to reach a justified belief. Overall, Rosa defends suspension of judgment as a valuable epistemic attitude that contributes to rational inquiry and decision-making.
