Nietzsche's rhetoric in "The Antichrist" elicits a very visceral reaction. In Nietzsche's contempt for Christianity and his picture of a transvaluation of the Christian ideals, he launches a tirade that can be bewildering, contradictory, and seemingly unstoppable. One either joins his shouting, or tries his or her best to shut him up.
In this bold and balanced work, a Christian psychologist and philosopher of note, Karl Jaspers, dismantles Nietzsche piece by piece, and in the process forms a picture for us of the fundamentally Christian attitudes and assumptions he held that allowed him to launch his attack in the first place. It's a brilliantly penetrating little study, and it is surprising at every turn to see how Jaspers can calmly demonstrate the weaknesses of Nietzsche's arguments while also continuously showing his lasting importance.
Jaspers' thesis is that Nietzsche's hatred of Christianity (including its moral, doctrinal, sociological, and political aspects) stemmed from his own fundamental Christian outlook. This is demonstrated by his highly contradictory statements about Christianity made throughout his life. The reader who believes that all this philosopher's opinions are admitted in "The Antichrist" is simply mistaken; in journals, letters, and other works, Nietzsche presents a highly problematic opinion of Christianity. Jaspers moves on from this to posit that such inconsistent statements reveal Nietzsche's goal: he uses the very instincts, discoveries, and vocabulary of Christian theology in his attempt to surpass it; and that was his goal: to surpass, not merely beat into submission and then dismantle.
What Jaspers calls Nietzsche's "unconditionality," that is, his "extreme morality and truthfulness," comes not from Greek or Latin thinking or from his own originality; it comes from 1900 years of Christian authority. This is the Christian authority from the Bible and the Fathers which stressed the Sermon on the Mount and the Commandments. The problem is, that Nietzsche never comes close to offering a sustained interaction with, say, the thought of Augustine or Thomas Aquinas. If he had, then perhaps he would have better appreciated their own endeavor for truth and "manliness" as Nietzsche puts it.
Another problem that Jaspers uncovers is Nietzsche's New Testament assumptions. For Nietzsche, the Gospels and the entire New Testament were distortions. So, some key questions are: How does Nietzsche know the "original" Jesus? Can there be a Jesus stripped of the "accretions" of story, miracle, and teaching? Nietzsche is not enough of a philologist to take note that the "Christ Hymns" in Paul's writings differ from his letters in their vocabulary and syntax; these were teachings Paul received from others and then incorporated into his letters. These were therefore the oldest teachings the Christian communities spoke, and they were written down at an incredibly early date - before the Gospels. Nietzsche doesn't care; for his attack to work, Jesus of history must be a heroic figure who presented a way to live, not a Savior who presented a relationship to join.
Jaspers takes Nietzsche to task for his view of the world-historical process. Is there the possibility for a philosophy of history apart from Christian origins? Jaspers says, "No. There is not," for the very idea of a "hyperphysical history" of the world is of Christian origin. Nietzsche's demand for complete truthfulness is also not to be found apart from the advent of Christianity in Western thought. This single-minded obsession is not Greek, but Monastic.
The thinking of Nietzsche is drastic and wild and contradictory, and in this lies his great power and influence. Jaspers writes, "It can only be motion itself - that is to say, a thinking which never closes but widens the space, which prepares no ground but creates possibilities for an unknown future" (97). Being associated with Nietzsche should lead to a "loosening process," where each one of us looks at his or her assumptions and uncovers what he or she has been concealing. Nietzsche is a challenge to each one of us, and his challenge to Christianity is Christian in origin, as Jaspers demonstrates. After reading Nietzsche, one must see for himself or herself what one is standing on.
