Models for Liars in Bradwardine's Theory of Truth
نویسنده
چکیده
Stephen Read’s work on Bradwardine’s theory of truth is some of the most exciting work on truth and insolubilia in recent years [4, 5]. In this paper, I give models for Read’s formulation of Bradwardine’s theory of truth, and I examine the behaviour of liar sentences in those models. I conclude by examining Bradwardine’s argument to the effect that if something signifies itself to be untrue then it signifies itself to be true as well. We will see that there are models in which this conclusion fails. This should help us elucidate the hidden assumptions required to underpin Bradwardine’s argument, and to make explicit the content of Bradwardine’s theory of truth. As has been made clear in many of the papers in this volume, the crucial feature in Bradwardine’s theory of truth is the notion of signification. Expressed by a ‘connecticate’, which I shall write with the simple infix colon “:”, whenever t is a singular term and p is a sentence

An important observation is that thinking of, and committing to, future actions often evoke vivid and detailed mental images...

متن کاملBlinking During and After Lying
We tested the hypothesis derived from eye blink literature that when liars experience cognitive demand, their lies would be associated with a decrease in eye blinks, directly followed by an increase in eye blinks when the demand has ceased after the lie is told. A total of 13 liars and 13 truth tellers lied or told the truth in a target period; liars and truth tellers both told the truth in two...

In this paper we focused on children’s deception (10-12 years, Experiment 1), and adult’s ability detect deception in children (Experiment 2). The self-presentational perspective (DePaulo, 1992) suggests that both liars and truth tellers will try to act in a convincing manner to be assessed as truth tellers. By asking unanticipated questions we put the liars in the following dilemma: If they di...
