Opposed to a biological and voluntary conception of the "Wille zur Macht", Heidegger also argued that the will to power must be considered in relation to the "Übermensch" and the "thought of eternal recurrence"—although this reading itself has been criticized by Mazzino Montinari as a "macroscopic Nietzsche". Gilles Deleuze also emphasized the connection between the will to power and eternal return. Both Jacques Derrida and Gilles Deleuze were careful to point out that the primary nature of will to power is unconscious. This means that the drive to power is always already at work unconsciously, perpetually advancing the will of the one over the other. This thus creates the state of things in the observable or conscious world still operating through the same tension. Derrida is careful not to confine the will to power to human behavior, the mind, metaphysics, nor physical reality individually. It is the underlying life principle inaugurating all aspects of life and behavior, a self-preserving force. A sense of entropy and the eternal return, which are related, is always indissociable from the will to power. The eternal return of all memory initiated by the will to power is an entropic force again inherent to all life.
