+It was one of the surprises of the 1950s that two of the most prized general results of
+Lagrangian quantum field theory (also distinguished by being well verified experimentally), the CPT Theorem and the Connection of Spin With Statistics, turned
+out to be theorems of the general theory of quantized fields with only the above-
+mentioned hypotheses. The proofs were easy consequences of a characterization of
+the theories in terms of vacuum expectation values.
