Abstract
In paleontology, the discovery of funeral rites is an important factor in determining the degree of social awakening of a hominid.
This awareness of death is an engine of social cohesion (uniting to resist disasters and enemies) and action (to do something to leave a trace). It is an important element of metaphysical reflection. This is also what gives the symbolic power to acts such as homicide and suicide.
According to Plato, death is the separation of soul and body. Finally freed from his fleshly prison, the immortal soul can freely reach the sky of Ideas, Eternity, the domain of philosophers. (cf. Phaedo)
