Sloterdijk argues that science is not just theory, but also practice. In the same way that athelics train for their competitions in their different fields of sports, so also must an academic train in order to become a good scientist; improving knowledge and attaining wisdom.
|Friedrich Wilhelm Nietzsche|
Husserl invented an expression in 1913 (Ideas for a Pure Phenomenology) in order to answer this question. He called the expression for epoché, and is best illustrated as the way a customer strolls around in a store withou buying anything. We keep existence at a distance by stepping back from all forms of existential involvement. Sloterdijk argues that Husserl failed in his attempt to raise philosophy to the status of a strict science.
Sloterdijk offers an alternative way of thinking and brings life back to Nietzsche by focusing on near-death experiences. One must lose onself in order to find onself. Or as Socrates once stated before he drank his cup of poison, "The one aim of those who practice philosophy in the proper manner is to practice for dying and death". We need to become involved in our own lives in order to understand Nietzsches argument that all cognition is local in character and that no human observer is able to go as far as really transcending his own location.
The book seems to be a nice introduction to the philosophy of Sloterdijk. The next book from his hands that I am reading is Rage and Time - A Psychopolitical Investigation.
