Louis Pasteur, speech at celebration honoring his seventieth birthday, the Sorbonne, Paris, France (December 27, 1892). Pasteur's son read the speech of thanks because of the weakness of his father's voice. René Vallery-Radot, The Life of Pasteur, trans. Mrs. R. L. Devonshire, vol. 2 (1902), p. 297.

Stevenson used a version of this passage which varies slightly from the arrangement and translation given above: "Not to destroy but to construct, / I hold the unconquerable belief / that science and peace will triumph over ignorance and war / that nations will come together / not to destroy but to construct / and that the future belongs to those / who accomplish most for humanity".
