Get an original essay This assessment will analyze lying from a social and philosophical aspect. This assessment will begin by giving the definition of lying. Considering the definition of lying, part of this essay will be devoted to various opinions of philosophers in order to prove that it is not always bad to lie since in certain circumstances lying is justified. In order to understand why someone lies or uses lies to deceive or persuade someone else we need to define it. Therefore, a lie is a statement made by someone who does not believe it with the intention that someone else will be led to believe it. It could be argued that this definition leaves open the possibility that a person is lying, even if they say what is true. For example, a man who does not know that his watch is one hour late says: it is ten o'clock, thinking that it is nine o'clock, he gives what he thinks is the wrong time; but it turns out it's the right time. According to this definition, lying has three important parts. First of all, a lie is an assertion, a proposition and a statement. Second, a lie includes disbelief or lack of belief on the part of the speaker and third, the last two elements of a lie are obvious. This definition also implies that for a lie to be justified, there must be intention. If the speaker does not intend to make someone believe what he does not believe, he is not lying. At this point, it is crucial to define the meaning of the intention. We could say that by intention, someone means that if someone is lying, they wish to make someone believe something – the same motive that so often drives us to tell the truth. However, a statement whose content is made with the intention of deceiving the hearer about that content constitutes a lie according to Williams. Williams also adds that "it seems to me that in everyday usage that is clearly its definition." From my point of view, this definition is closer to everyday life; however, an explanation is needed as to how the liar intends to deceive the listener with his assertions. Lying is therefore a form of intentional deception. More precisely, we can say that the liar's primary intention is to deceive about certain facts and that the liar aims to accomplish this deception by asserting what he believes to be false. A liar, in order to achieve his goal, he tries to deceive about this fact by further deceiving about his beliefs on this subject. Before continuing this evaluation with the theories of lying, it is essential to clarify the types of it. Thus, in agreement with Vincent and Castelfranchi, a distinction must be made between several types of lying action in order to qualify an action as lying. Thus, pretending or simulating, acting, lying, lying indirectly, insinuation, reticence, half-truths, fudging conditions or presuppositions, deliberate ambiguity, pretending to lie and pretending to act or joke constitute manners to lie. The above types of lies may constitute cases of lying while telling the truth. After explaining what constitutes a lie and its different types, this evaluation will continue by representing some theories in the practice of.
