A simlar thought by other(s):

"A mathematician who is not also something of a poet will never
      be a complete mathematician." - Karl Weierstrass

 "The mathematician's patterns, like the painter's or poet's, must
      be beautiful.  The ideas, like the colours or the words, must fit
      together in a harmonious way.  Beauty is the first test: There is
      no permanent place in the world for ugly mathematics.
         - G. H. Hardy
