Bevan saw Gaitskell's speech in advance and made no objection to it at the time. Gaitskell did not rule out further nationalisation, but saw it as a means to an end, pouring scorn on the idea that Labour should be committed to nationalising "the whole of light industry, the whole of agriculture, all the shops, every little pub and garage". Bevan now claimed he had "misunderstood or misheard" what Gaitskell planned and was reported to be "absolutely livid" and "wondering whether to blow the whole thing wide open". In the end he made a conciliatory speech, mentioning that Barbara Castle (who had attacked Gaitskell's proposal) and Gaitskell had both quoted his own dictum that Socialism was about controlling the "commanding heights" of the economy. He argued that according to the principles of Euclid if two things are equal to a third thing they must both be equal to one another, and so there could not be any real difference between Castle and Gaitskell.
