Abstract
In my essay I will argue that lying and deception have often been treated in isolation, only from the point of view of their moral and ethical dimension. However, lying is a part of the life of society, of the community, and it should be judged as such.
I will analyse the concepts of lying, deception, spins and half-truths, as defined by Thomas L. Carson.
Metaphors will be studied from the point of view of their truth-value. Carson's approach will be compared to that of Friedrich Nietzsche, and further, the moral dimension of lying will also be included in my work.
