Progress Is Impossible Without Change And

This comes from Everybody's Political What's What?, a wide-ranging political treatise Shaw published in 1944 at the age of 87 — one of his last major prose works. The book argued for sweeping reforms to government, education, and society, and the line appears on page 330 of the Dodd, Mead edition as part of his broader case that intellectual rigidity is the fundamental obstacle to social progress. Shaw himself embodied the principle: he was still writing plays, essays, and polemics well into his nineties.
