To us ... the only acceptable point of view appears to be the one that recognizes both sides of reality-the quantitative and the qualitative, the physical and the psychical-as compatible with each other, and can embrace them simultaneously ... It would be most satisfactory of all if physis and psyche (i.e., matter and mind) could be seen as complementary aspects of the same reality.

Physics is very muddled again at the moment; it is much too hard for me anyway, and I wish I were a movie comedian or something like that and had never heard anything about physics!
