“What are wanted .... are not Constitutions and Revolutions, nor all sorts of Conferences and Congresses, nor the many ingenious devices for submarine navigation and aerial navigation, nor powerful explosives, nor all sorts of conveniences to add to the enjoyment of the rich, ruling classes; nor new schools and universities with innumerable faculties of science, nor an augmentation of papers and books, nor gramophones and cinematographs, nor those childish and for the most part corrupt stupidities termed art-but one thing only is needful: the knowledge of the simple and clear truth which finds place in every soul that is not stupefied by religious and scientific superstitions -- the truth that for our life one law is valid -- the law of love, which brings the highest happiness to every individual as well as to all mankind.”
