Pauli letter collection: letter to Werner Heisenberg

Pauli writes about the planned Bohr Festschrift. He makes some remarks about Bohr's attempt to create a kind of a religion of complementarity as in former times one has made "energetics" into a sort of "world religion". But the basis of physics is too narrow for such attempts. One should resist the natural impulse which grows with age, to bring everything under one roof.
