“You cannot hope to build a better world without improving the individuals. To that end each of us must work for his own improvement, and at the same time share a general responsibility for all humanity, our particular duty being to aid those to whom we think we can be most useful.”
Pierre Curie (1923), as translated by Charlotte Kellogg and Vernon Lyman Kellogg, p. 168

UN Press Release SG/360 (22 December 1953)
Context: Our work for peace must begin within the private world of each one of us. To build for man a world without fear, we must be without fear. To build a world of justice, we must be just. And how can we fight for liberty if we are not free in our own minds? How can we ask others to sacrifice if we are not ready to do so?... Only in true surrender to the interest of all can we reach that strength and independence, that unity of purpose, that equity of judgment which are necessary if we are to measure up to our duty to the future, as men of a generation to whom the chance was given to build in time a world of peace.
