The Normative Value of Truth and the Problem of Lie

The article concerns the normative value of truth in relation to lie. Based on arguments derived primarily from ancient philosophers (Eubulides, Plato, Aristotle), medieval philosophers (St. Augustine, St. Thomas Aquinas), the thinker of the Renaissance---Machiavelli, the main philosopher of the Enlightenment--Kant, the 19th-century author of Beyond Good and Evil (Nietzsche), and contemporary thinkers such as Derrida and Lacan, the author considers here truth as a normative value. Lying is relative to the truth, and it has no ontological legitimacy, even it cannot exist without truth itself. In the final part of the article, the author concludes that the truth, however, cannot lead to clearly had effects, be harmful or cause pain disproportionate to the effects caused by lie. Therefore, it must coexist with the good--the other parent value. Only when both values complement each other can we talk about the normative value of truth. The truth should be correlated with other values on which value systems are based, especially the good of a person or group of persons, avoiding harm towards others, and the protection of a person's health and life. Only then can the truth be appropriate to use. It is not an immovable foundation, but a dynamically functioning value, in which language and the ethical (active) dimensions provide the value of the specified situations. The truth can be a double-edged sword: It may hurt, but it can defend itself. The latter function seems to be the most important type of the normativity of truth. 展开更多

Russian and English View on Lies in Conflict Dialogues—— Analysis of Conflict Communication Acts in Russian and English Fiction

Is the attitude to them the same in different cultures? If not, what differences are there? An answer to these and some other questions is being sought in the paper. Producing a false utterance, the sender deprives the communication partner of the right to receive full information. The article presents views of Russians and representatives of Anglo-American culture on telling lies drawing the readers' attention to very serious situations, such as family conflicts between spouses, aggravated with lies. The material for analysis is taken from the texts by Russian playwright Anton Chekhov and the American novel writer Irwin Shaw. The analysis is based on the study of verbal and non-verbal markers of false utterances generated by quarreling spouses. A complex method of researching the literary material combining linguistic, extra-linguistic, and paralinguistic analysis of conflict speech acts with false utterances of different kinds is applied. 展开更多

Lying is a kind of pragmatic phenomenon.From the perspective of the definition of a lie,a lie is a kind of speech act that deliberately conceals the facts or provides self-deemed false information to achieve the purpose of deception.The film Catch Me If You Can tells a story of an FBI agent chasing a talented young criminal.There are a variety of lies in the film,therefore this paper takes the lies in the movie as the main research material.Based on relevance theory,politeness principle,face theory in pragmatics,this paper analyzes the pragmatic features of lies from a pragmatic perspective,including gradability,subjectivity and flexibility.Using the communicative view,context view and relevance in the relevance theory can explain the subjectivity and flexibility of lies. 展开更多

This is a survey of local and global classification results concerning Dupin hypersurfaces in S^(n)(or R^(n))that have been obtained in the context of Lie sphere geometry.The emphasis is on results that relate Dupin hypersurfaces to isoparametric hypersurfaces in spheres.Along with these classification results,many important concepts from Lie sphere geometry,such as curvature spheres,Lie curvatures,and Legendre lifts of submanifolds of S^(n)(or R^(n)),are described in detail.The paper also contains several important constructions of Dupin hypersurfaces with certain special properties. 展开更多

Deception detection is regarded as a concern for everyone in their daily lives and affects social interactions.The human face is a rich source of data that offers trustworthy markers of deception.The deception or lie detection systems are non-intrusive,cost-effective,and mobile by identifying facial expressions.Over the last decade,numerous studies have been conducted on deception detection using several advanced techniques.Researchers have focused their attention on inventing more effective and efficient solutions for the detection of deception.So,it could be challenging to spot trends,practical approaches,gaps,and chances for contribution.However,there are still a lot of opportunities for innovative deception detection methods.Therefore,we used a variety of machine learning(ML)and deep learning(DL)approaches to experiment with this work.This research aims to do the following:(i)review and analyze the current lie detection(LD)systems;(ii)create a dataset;(iii)use several ML and DL techniques to identify lying;and(iv)create a hybrid model known as LDNet.By combining layers from Vgg16 and DeneseNet121,LDNet was developed and offered the best accuracy(99.50%)of all the models.Our developed hybrid model is a great addition that significantly advances the study of LD.The findings from this research endeavor are expected to advance our understanding of the effectiveness of ML and DL techniques in LD.Furthermore,it has significant practical applications in diverse domains such as security,law enforcement,border control,organizations,and investigation cases where accurate lie detection is paramount. 展开更多
