Reciprocal empathy means that one puts himself into the other\u2019s situation, including the other\u2019s empathization back to himself. The logic REL\u03b2 is a fixed-point extension of epistemic logic KD with perception operators. In REL\u03b2, interpersonal (and intrapersonal) epistemic depths are bounded by \u03b2 &lt; \u03c9. Yet, the logic REL\u03b2 is shown to be sound and complete with respect to the standard Kripke semantics for KD but with the restriction of permissible formulae. Our aim is to study the syntactical logic REL\u03b2, and Kripke semantics is needed for a full study. With respect to interpersonal depths, our framework has some subtlety with infinity or unboundedness, which we call latent infinity. We study how latent infinity is hidden. We apply REL\u03b2 to an example of communication and coordination due to David Lewis. It is given as a formal theory within REL\u03b2. This shows that our approach has large potential for studies of societal problems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Tai-Wei Hu (University of Bristol)<br \/>\nDate and Time: Friday, March&nbsp;21st 2025, 12:30-14:00<br \/>\nVenue: ILLC Seminar Room F1.15, Science Park 107 and\u00a0online.<br \/>\nTitle: Logic of Reciprocal Empathy: Shallow Interpersonal Reasoning and Latent Infinity.<br \/>\nAbstract.
