BIOUNCERTAINTY - ERC Starting Grant no. 805498
17th of October 2019: Research seminar - Konrad Rudnicki (University of Antwerp) - The Liar lied. Experimental investigation of the Liar paradox
We have the pleasure to invite You for a research seminar in the ‘BIOUNCERTAINTY’ research project. The title of the seminar is ‘The Liar lied. Experimental investigation of the Liar paradox’ and it will be delivered by Konrad Rudnicki from University of Antwerp. The seminar will take place on Thursday, 17th of October, at 5:30pm in room 25 of the Institute of Philosophy, 52 Grodzka Street.
Konrad Rudnicki is a PhD student at the University of Antwerp at the Department of Communication. He is working on a project combining neuroendocrinology and social research on interpersonal interaction. In addition, in cooperation with the Faculty of Cognitive Sciences of the University of Lodz and the Faculty of Cognitive Sciences of the University of Social Sciences and Humanities in Warsaw, it explores the neuronal foundations of human perception of philosophical paradoxes.
His seminar will concern the article ,,Psychophysiological approach to the Liar paradox: Jean Buridan’s virtual entailment principle put to the test", that can be found here: https://link.springer.com/article/10.1007/s11229-019-02107-x .
Abstract: A psychophysiological experiment was conducted to test the predictions of the virtual entailment principle proposed by Jean Buridan to resolve the Liar paradox. This principle states that every sentence in natural language implicitly asserts its own truth. Adopting this principle means that the Liar sentence is not paradoxical but false, because its content is contradictory to what is virtually implied. As a result, humans should perceive the Liar sentence the same way as any other false sentence. However, thanks to modern advancements in psychophysiology, it became possible to empirically investigate if the human brain really perceives the Liar sentence like a false sentence. We designed and conducted an experiment to examine brain activity in response to true sentences, false sentences and self-referential sentences (including the Liar and the Truthteller). Our results provide support for the Buridan’s hypothesis and show that the Liar sentence is processed by the human brain identically to false sentences, while the Truthteller sentence is perceived identically to true sentences.
