What is Philosophy?

What philosophy is as such cannot be answered immediately. If it were so easy to agree about a definite concept of philosophy, one would only need to analyze this concept to see oneself at once in possession of a philosophy of universal validity. The point is this: philosophy is not something with which our mind, without its own agency, is originally and by nature imbued. It is throughout a work of freedom. It is for each only what he has himself made it; and therefore the idea of a philosophy [is] only the result of philosophy itself; a universally valid philosophy, however, [is] a vainglorious figment of the imagination.
