Nietzsche and the Pre-Platonic Philosophers

"The intellect must not only desire serreptitious delights; it must become completely free and celebrate Saturnalia. The free spirit surveys things, and now for the first time mundane existence appears to it worthy of contemplation as a problem. The is the true characteristic of the philosophical drive: wonderment at that which lies before everyone. The most mundane phenomenon is Becoming: with it Ionian philosophy begins. The problem returns infinitely intensified for the Eleatics: they observe, namely, that our intellect cannot grasp Becoming at all, and consequently they infer a metaphysical world. All later philosophy struggles against Eleaticism; that struggle ends with skepticism. Another problem is purposiveness in nature; with it the opposition of spirit and body will enter philosophy for the first time. A third problem is that concerning the value of knowledge. Becoming, purpose, knowledge-- the contents of pre-Platonic philosophy."
