High Quality Content by WIKIPEDIA articles! God`s utility function is a phrase coined by Richard Dawkins in his book River Out of Eden. "God`s utility function" is the third chapter in this book. Dawkins uses this phrase to expound the Gene-centered view of evolution by equating the phrase to the meaning of life or the purpose of life. This is the why question about life which philosophers and theologians have been pondering in vain for ages, and is a counterpart to the how question about nature which engineers have been able to resolve successfully.
