Shifting Point

"I have never believed in a single truth. Neither my own, nor those of others. I believe all schools, all theories can be useful in same place, at some time. But I have discovered that one can only live by a passionnate, and absolute, identification with a point of view.
However, as time goes by, as we change, as the world changes, targets alter and the viewpoint shifts. Looking back over many years of essays written, ideas spoken in many places on so many varied occasions, one thing strikes me as being consistent. For a point of view to be of any use at all, one must commit oneself totally to it, one must defend it to the very death. Yet, at the same time, there is an inner voice that murmurs:
"Don't take it too seriously. Hold on tightly, let go lightly."
