Besides these, it also studies the notion of the “pariah” using the different strata that make up human society, such as literature. The book also presents the perceptions of lexicologists and psychologists, because behind the word there is the object, which is understood differently by the human psyche because it is included in value systems varying from one sociocultural group to another.
