Meeting the Alien: An Introduction to Exosociology by Andreas Anton, Michael Schetsche

What can we say about a book titled An Introduction to Exosociology? Initially, it might seem that there's nothing to say: it would be a blank book, as we have no knowledge of life beyond our planet, nor have we had any contact with extraterrestrial civilizations. I’m not being cynical; as you’ll see, the authors manage to provide a thorough study of the state of the art in this subject.

So, what do the authors mean by this book? On one hand, they address humanity’s attempts to tackle this issue. For example, the growing field of astrobiology and its research into life forms on other planets in our solar system or beyond.

As the title suggests, the book explores how extraterrestrial civilizations might organize themselves and communicate, as well as the potential effects of such interactions on human society. The authors’ approach is primarily academic and scientific, but they also incorporate—rightly, in my opinion—elements of science fiction to illustrate theories and dilemmas related to contact with extraterrestrials. For instance, the Dark Forest hypothesis from the eponymous book by the brilliant Cixin Liu.

The book addresses unconventional topics from both a sociological and scientific perspective, touching on areas like astrobiology, SETI (Search for Extraterrestrial Intelligence through radio signals), and the lesser-known SETA ((Search for Extraterrestrial Artifacts, a form of astro-archeology, inspired by the Fermi Paradox). The authors also offer a critical perspective, discussing, for example, the debate about sending active signals into space with the intent to make our planet known. Or, in the case of SETA, the idea that it dangerously flirts with pseudosciences such as ufology.

It also considers the important question of how the discovery of extraterrestrial life might impact our political and social structures, and it provides a study of various cases: how the discovery of extraterrestrial life or an artifact from another civilization might affect us, and so on.

In summary, Meeting the Alien: An Introduction to Exosociology is a very interesting book for anyone interested in the study of extraterrestrial life and its implications.
