Despite the criticisms that Levinas addresses to Nietzsche throughout his writing, he also praises Nietzsche’s legacy. In Humanism of the Other, he indicates how the Nietzschean man is “‘reducing’ being, […] undoing by the non-saying of dance and laughter […] the worlds that weave the aphoristic verb that demolishes them; retiring from the time of aging […] by the thought of the eternal recurrence”. Interpreting Nietzsche’s ambiguous thought of the eternal recurrence as a source of youth, Levinas brings to light (...) the fertility of Nietzsche’s concept of temporality. The aim of this paper is first to render Nietzsche’s thought on time more explicit, focusing on his approach to eternal recurrence, and then to study Levinas’ own approach to time. In the end, it will be possible to understand better Levinas’ interpretation of Nietzsche, and to shed light on some important similarities between these two different approaches to time. (shrink)

“God is dead!” This is one of the most famous claims in Nietzsche’s philosophy, difficult to fully affirm. While the higher men fail to overcome the ghost of God, Zarathustra joyfully affirms God’s death. This affirmation deconstructs the metaphysical and moral concept of “divinity,” turning it into a metaphor. The new metaphor of the divine, mainly developed through the figure of Dionysius, expresses the capacity of affirming life beyond the old values, related to the dead God. It also involves the (...) creation of a higher body beyond the body of despair, associated with these values. The purpose of this paper is to study the relationship between the death of God and the body in Nietzsche’s account by analyzing the meanings of this death for the higher men, the question of the divine in Zarathustra’s account, and the status of the Dionysian body.

The quality of arm movements typically improves in the sub-acute phase of stroke affecting the upper extremity. Here, we used whole arm kinematic analysis during reaching movements to distinguish whether these improvements are due to true recovery or to compensation. Fifty-three participants with post-acute stroke performed ∼80 reaching movement tests during 4 weeks of training with the ArmeoSpring exoskeleton. All participants showed improvements in end-effector performance, as measured by movement smoothness. Four ArmeoSpring angles, shoulder horizontal rotation, shoulder elevation, elbow rotation, (...) and forearm rotation, were recorded and analyzed. We first characterized healthy joint coordination patterns by performing a sparse principal component analysis on these four joint velocities recorded during reaching tests performed by young control participants. We found that two dominant joint correlations [SH with elbow rotation and SE with forearm rotation] explained over 95% of variance of joint velocity data. We identified two clusters of stroke participants by comparing the evolution of these two correlations in all tests. In the “Recoverer” cluster, both joint correlations converged toward the respective correlations for control participants. Thus, Recoverers relearned how to generate smooth end-effector movements while developing joint movement patterns similar to those of control participants. In the “Compensator” cluster, at least one of the two joint correlations diverged from the corresponding correlation of control participants. Compensators relearned how to generate smooth end-effector movements by discovering various new compensatory movement patterns dissimilar to those of control participants. New compensatory patterns included atypical decoupling of the SE and forearm joints, and atypical coupling of the SH rotation and elbow joints. There was no difference in clinical impairment level between the two groups either at the onset or at the end of training as assessed with the Upper Extremity Fugl-Meyer scale. However, at the start of training, the Recoverers showed significantly faster improvements in end-effector movement smoothness than the Compensators. Our analysis can be used to inform neurorehabilitation clinicians on how to provide movement feedback during practice and suggest avenues for refining exoskeleton robot therapy to reduce compensatory patterns.
