Unwin conducted this landmark study of 86 civilizations through 5000 years of history and found a positive correlation between the cultural achievement of a people and the sexual restraint they observe. The evidence is that human societies are free to choose either to display great energy or to enjoy sexual freedom; it appears they cannot do both for more than one generation. The whole of human history does not contain a single instance of a group becoming civilized unless it has been absolutely monogamous, nor is there any example of a group retaining its culture after it has adopted less rigorous customs\"--Back cover.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFormat:\u003c\/strong\u003e Paperback\u003c\/p\u003e\u003cp\u003eAll books at Vastela are pre-owned.
