The Lie Detector

In this essay, Lewis Thomas insists in that we are biologically designed to be truthful to each other. Also, he questions the capacity of lie detector to inform us that untruthful behavior can gradually undermine our vascular system. I agree with Lewis Thomas because it is not necessary to use machines in order to detect if someone is lying. We are genetically designed to show up if we are lying. That is why once we lie, in one way or another, our body discloses that we are hiding something. I complete agree when he says that “Truths is a fundamental requirement for our kind of existence.” Due to the fact that we live in society, we need each others, so if we do not truths each other the society does not function. In addition, although we lie, our behavior contradicts our words. Consequently, it is not necessary a machine to see if you are lying, yourself always discloses you.
