Unwin argues that Zoistic societies have the least amount of social and mental energy. The next class is Monistic', followed by the Deistic societies, and finally, the Rationalistic, or most developed, which exercises the most sexual restraint and expresses the most energy. The book concludes with the assertion that, in order to maintain a "Rational", energetic, society, sexual drive should be controlled and shifted to more productive work, and that women should enjoy the same legal rights as men.

He was obviously incorrect about Rationalistic societies. We could rationalize anything, including the vast expansion of pornography and gross excessses, as well as persecution of scapegoats for our common indiscretions.

But the connection between sexual self-restraint and ability to build and maintain complex societies is the most interesting point in this book and perhaps modernity confirms it via live experimentation on unwitting subjects.
