Rosen never looked for controversy and was in the beginning surprised by the the vehemence of his critics. In his introduction to Life Itself he presented his strategy -- "I have tried to address these problems of organization and exposition in the same way as I approach research, namely, to try to let the problems tell me what to do. Everything to be found herein, and the manner in which it is expressed, is what it is because it seemed to me to be necessary. And about each, I can say in truth that it is the best I can do. It is for the reader to say whether this has been enough."
