The history of the family dates from 1861, the year of the publication of Bachofen's Mutterrecht (maternal law) Engles makes the following propositions:

1. That in the beginning people lived in unrestricted sexual intercourse, which he dubs, not very felicitously, hetaerism.

2. That such an intercourse excludes any absolutely certain means of determining parentage; that consequently descent could only be traced by the female line in compliance with maternal law; and that this was universally practiced by all the nations of antiquity.

3. That consequently women as mothers, being the only well known parents of younger generations, received a high tribute of respect and deference, amounting to a complete women's rule (gynaicocracy), according to Bachofen's idea.

4. That the transition to monogamy, reserving a certain woman exclusively to one man, implied the violation of the primeval religious law (i.e., practically a violation of the customary right of all other men to the same woman), which violation had to be atoned for its permission purchased by the surrender of the women to the public for a limited time.

This interest in space was rooted in his understanding of the smallness and vulnerability of humanity measured against the immense size and power of the universe. This profound philosophical humility, mixed with personal exuberance, comes through in Conversations with Carl Sagan. In interviews and profiles, Sagan discusses with verve a wide variety of topics—the environment, nuclear disarmament, religion, politics, extraterrestrial life, astronomy, physics, robotics. Whether he is discussing his science fiction or his well-researched nonfiction works, his voice embraces reason and skepticism.

This volume shows how Sagan, a lifelong skeptic, refined his views and expressed amazement that Earth, for all his belief in extraterrestrial life, encompasses everything about which he cared.
