How did Nietzsche and Sartre come to represent alternative modes of philosophy as antithetical thinkers? What exactly is their philosophical connection and how far does it extend?

Tracing the connections between the existentialist philosophies of Nietzsche and Sartre, Nik Farrell Fox provides new readings attuned to questions of the self, politics and ethics. From their earliest to final writings, Fox brings into critical view the full trajectory of their lives and philosophy to reveal the underexplored parallels that connect them. Through engaging with new Nietzsche and Sartre studies as authoritative strands of interpretation, this book identifies both philosophers as twin thinkers of a deconstructive and paradoxical logic. Fox further re-examines their work in light of contemporary debates concerning posthumanism, vibrant materialism, quantum theory and speculative realism.

The Parallel Philosophies of Sartre and Nietzsche presents two iconic existentialists as thoroughly contemporary thinkers whose complex, rich, and sometimes-ambiguous philosophy, can illuminate our present posthuman reality.
