“I believe,
therefore, that although it is not the case today, that there may some day come
a time, I should hope, when it will be fully appreciated that the power of
government should be limited; that governments ought not to be empowered to
decide the validity of scientific theories, that that is a ridiculous thing for
them to try to do; that they are not to decide the various descriptions of
history or of economic theory or of philosophy. Only in this way can the real
possibilities of the future human race be ultimately developed.”
