OT: One man's Nietzsche to another ...

Da Wiz closed with:

Do you believe that the sciences would ever had
arisen and became great if there had not beforehand
been magicians, alchemists, astrologers and WiZards,
who thirsted and hungered after abscondite and
forbidden powers?
Friedrich Nietzsche
Die fröhliche Wissenschaft, IV,
1886

To which one might supply this:

"But science, spurred on by its energetic notions, approaches
irresistibly those outer limits where the optimism implicit in logic
must collapse. For the periphery of science has an infinite number of
points. Every noble and gifted man has, before reaching the mid-point
of his career, come up against some point of the periphery that defied
his understanding, quite apart from the fact that we have no way of
knowing how the area of the circle is ever to be fully charted. When
the inquirer, having pushed to the circumference, realizes how logic in
that place curls about itself and bites its own tail, he is struck with
a new kind of perception: a tragic perception, which requires, to make
it tolerable, the remedy of art."
Friedrich Nietzsche
The Birth of Tragedy 1872
