Death is generally considered not only one of the few certainties of life, but also one of its ultimate mysteries. The act of defining and conceptualizing death always leads to other questions about the human experience such as the body and social identity. The abstract idea of death can only made present through metaphors: conceptual constructs that are pervasive not only in language but also in thought and practice. Death thus appears to be no more than a word of which the definition depends rather on the social context than on one primordial essence. Moreover, understanding death inevitably involves defining life: both concepts are related to one another in a dynamic relationship.
