One goes to an older physician, in part, for their wisdom, but doctors spend much of their formative years working on memory enhancement; trying to recall long lists of differential diagnosis, studying for tests, etc. As physicians age and pursue their practices, they have to rely less on their memory and more on their underlying wisdom; their ability to think. The quote from Nietzsche above has given me perspective as both a thinking patient and a thoughtful practitioner of Medicine; now I'm lucky if I can remember how to spell N-i-e-t-z-s-c-h-e. He is responsible for many memorable and insightful quotes; actually, many quotes have been attributed to fictitious individuals with a misspelling of his last name [...tsche, ...tzche, etc., etzc., etsc.].
More important than his quotes, however, is the pervasive philosophy of the man; the sharp wisdom behind the numerous quotes. This philosophy has been referred to as 'THE WILL TO POWER': the driving force in humankind; inspiration, striving ambition, achievement. Here rests the omnipresent inspiration framed and propped up on the doctor's desk or hanging up on the examining room wall. But, let me play the devil's advocate, and suggest a terser and less ambivalent message to patients and doctors- 'JUST DO IT!' Enough of the quotes and philosophies; I've reached the conclusion that slogans trump quotes.
'NIKE NOT NIETZSCHE!'
