ABSTRACT
To sensation are related the object and its properties, its origin, and its concrete or abstract cause. An invisible mirror erases the living identity of each person and paralyzes the fecundity of the relations between them. When the relationship with the other is reduced to sensation, to simple affect, the other becomes an object, losing his qualities as subject. Whereas perception seems to be fitting for life, sensation seems more a path towards death. The economy of sensation is more quantitative than qualitative: feeling always wants to grow in intensity and continues along this path until death due to the lack of any controls. While perception can assist in the construction of intersubjectivity, sensation tends to erase one of the two subjects or reduce them both to a game between forces that are more or less individuated and controlled. Sensation overturns perception in the night of the soul, reducing it to passivity towards the already established order.
