Through a re-reading of the Freudian death drive, this work examines some specific as-pects that concern in particular the antilibidic life forms present in the subject, in the couple and in the social sphere. The Author proceeds starting from the premise of the pulsional mixture, coexistence and non-opposition of the two drives, libidinal and of death, to attempt a metapsychological and phenomenological description of a variegated and silent instance, to which she gives the name of "disinvestment". The traceability of the death instinct, as it "silent", is only through its derivatives, and the fact that they are subjects that escape our observation, makes the investigation not easy. We wonder ourselves how much excitability is tolerable to every human being, the problem of the "threshold", and it is therefore taken into account, finally, the important and underestimating defensive and subjectively action of the death drive, both as a pain-free maneuver, and as a necessary complement to human growth.
Keywords: Death drive, antilibidic life, disinvestment, extreme defense, excitability.
