Dialectic Of Enlightenment

The article analyzes methodological errors Theodore Adorno and Max Horkheimer’s Dialectic of Enlightenment, particularly their incorrect use of the concepts of mimicry and mimesis. The author of the article maintains that the leaders of the Frankfurt School made a mistake that threatens to undermine their argument when they juxtaposed mimesis and the attraction to death, which has led philosophers to trace back to mimesis the desire for destruction that is found in a civilization constructed by instrumental reasoning. The author reviews the arguments of the Dialectic of Enlightenment and emphasizes the unsuccessful attempt to fuse Freudian and Hegelian methods, which exposes the instability of opposing scientific reasoning to “living” nature. Some amusing quotations from Roger Caillois, who refused to think of mimesis as something entirely rational, are also brought to bear. As Brassier gradually unfolds Adorno and Horkheimer’s thesis, he indicates the consequences of their mistake, which confined thinkers to the bucolic dungeon of “remembering” the authentic nature that they cannot abandon because they have denied themselves access to both reductionist psychological models and to phenomenological theory as such. Brassier delineates the boundaries of this trap and notes the excessive attachment of the Dialectic of Enlightenment to the human. Brassier goes on to describe the prospects for a civilization of enlightenment: a mimesis of death in both senses (death imitates and is imitated) finds its highest expression in the technological automation of the intellect, which for Adorno and Horkheimer means the final implementation of the self-destructive mind. However, for Brassier it means the rewriting of the history of reason in space. This topological rewriting of history, carried out through an enlightenment, reestablishes the dynamics of horror more than mythical temporality: it will become clear that the human mind appears as the dream of a mimetic insect.

The stray fields produced by ferromagnetic layers in Superconductor/Insulator/Ferromagnet (S/I/F) heterostructures may strongly influence their superconducting properties. Suitable magnetic configurations can be exploited to manipulate the main parameters of the hybrids. Here, the nucleation of the superconducting phase in an external magnetic field that periodically oscillates along the film width is studied on the base of the numerical solution of the linearized system of Usadel equations. In addition, the effect of the magnetic configuration of the F-layer on the temperature dependence of the critical current density, Jc(T), is investigated in the framework of the Ginzburg–Landau phenomenological theory on the base of the oscillating model of a stray field. By following this approach, the Jc(T) dependence of a Nb/SiO2/PdNi trilayer is reproduced for different magnetic configurations of the PdNi layer.

Definition Of

Solitons are proposed as the agents of plastic and viscoelastic deformation in aligned polyethylene. Interactions between straight, parallel molecules are mapped rigorously onto the Frenkel–Kontorova model. It is shown that these molecular interactions distribute an applied load between molecules, with a characteristic transfer length equal to the soliton width. Load transfer leads to the introduction of tensile and compressive solitons at the chain ends to mark the onset of plasticity at a well-defined yield stress, which is much less than the theoretical pull-out stress. Interaction energies between solitons and an equation of motion for solitons are derived. The equation of motion is based on Langevin dynamics and the fluctuation–dissipation theorem and it leads to the rigorous definition of an effective mass for solitons. It forms the basis of a soliton dynamics in direct analogy to dislocation dynamics. Close parallels are drawn between solitons in aligned polymers and dislocations in crystals, including the configurational force on a soliton. The origins of the strain rate and temperature dependencies of the viscoelastic behaviour are discussed in terms of the formation energy of solitons. A failure mechanism is proposed involving soliton condensation under a tensile load.
