"Feynman comments that the renormalization theory is simply way to sweep difficulties under the rug. All the players, Tomonaga, Schwinger and Feynman feel that the theory that they have developed is intellectually not satisfactory. What they have provided is only a conservative solution but what is needed is a radical innovation and a revolutionary departure similar to what has been made in the nineteen thirties by Bohr, Heisenberg, Schrödinger and Dirac."
