Wolfgang Ernst Pauli Quotes
Although I have no objection to accepting the existence of relatively constant psychic contents that survive personal ego, it must always be born in mind that we have no way of knowing what these contents are actually like "as such." All we can observe is their effect on other living people, whose spiritual level and whose personal unconscious crucially influence the way these contents actually manifest themselves.

Wolfgang Ernst Pauli was an Austrian (and later American / Swiss) theoretical physicist and one of the pioneers of quantum physics. In 1945, after having been nominated by Albert Einstein, Pauli received the Nobel Prize in Physics for his "decisive contribution through his discovery of a new law of Nature, the exclusion principle or Pauli principle". The discovery involved spin theory, which is the basis of a theory of the structure of matter.
