"None of the human faculties should be excluded from scientific activity. The depths of intuition, a sure awareness of the present, mathematical profundity, physical exactitude, the heights of creative reason and sharpness of understanding, together with a versatile and ardent imagination and a loving delight in the world of the senses, they are all essential for a lively and productive apprehension of the moment."
- J. W. Goethe (1749 - 1832)
