"Later scientific theories are better than earlier ones for solving puzzles in the often quite different environments to which they are applied. That is not a relativist's position, and it displays the sense in which I am a convinced believer in scientific progress."

Mr. Russell is a great believer in versatility in all creative work. In any physical work he believes one can work many hours at a time, but in mental, creative work he believes one can do his best only for two hours at a time on any one subject, but he can work another two hours on another subject with equal freshness. He therefore sometimes works two hours a day on each of five different creations, and in that way can live five lives at a time.

— Walter Russell
