There are things that are so serious that you can only joke about them.

~ Werner Heisenberg

Whether we like it or not, modern ways are going to alter and in part destroy traditional customs and values.

~ Werner Heisenberg

The positivists have a simple solution: the world must be divided into that which we can say clearly and the rest, which we had better pass over in silence. But can anyone conceive of a more pointless philosophy, seeing that what we can say clearly amounts to next to nothing? If we omitted all that is unclear, we would probably be left completely uninteresting and trivial tautologies.

~ Werner Heisenberg

I am firmly convinced that we must never judge political movements by their aims, no matter how loudly proclaimed or how sincerely upheld, but only by the means they use to realize these aims.

~ Werner Heisenberg
