Because Freud introduces a nonplastic element in his definition of the plasticity of mental life -that is, elasticity- he ruins the possibility of thinking what he precisely wishes to think, the plastic coincidence between creation and destruction of form. The characterization of the death drive as “elastic” deprives it of its plastic power and of its capacity to resist the pleasure principle. ıf we are not able to prove that the destruction of form has and is a form, if form is always on the side of Eros and of pleasure, it becomes impossible to prove that there is anything beyond the pleasure principle.
