Philosophy and ethics

What is True North for medicine? Is there an enduring core value that serves as a reliable touchstone across the nearly infinite range of medical activities? Given how medicine and society change, can there even be an enduring True North? If we have one, are we pursuing it faithfully?  

I was asked by a colleague at work (someone who frequently but privately agreed with me but never spoke up publicly), “Why do you tilt at windmills?” Many have answered this better than I.

Niels Bohr said: “There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out what nature is. Physics concerns what we can say about nature…”

I think this parallels the enduring human drive to search for Truth. There may or may not be an absolute Truth, but it is wrong to think we can discover Truth or understand what Truth is.  Science, philosophy and religion are merely our endeavors to see what we can say about Truth.
