The late Rabbi Lord Jonathan Sacks, in his remarks from the International Colloquium on “The Complementarity of Man and Woman” in 2014, beautifully stated the impact monogamy has had on the historical evolution of human rights:
What makes the emergence of monogamy unusual is that it is normally the case that the values of a society are those imposed on it by the ruling class. And the ruling class…stands to gain from promiscuity and polygamy, both of which multiply the chances of my genes being handed on to the next generation. From monogamy the rich and powerful lose and the poor and powerless gain. So the return of monogamy…was a real triumph for the equal dignity of all. Every bride and every groom are royalty; every home a palace when furnished with love.
