Also a book by Donna Kossy highlighting individuals with "aberrant" or at least iconoclastic ideas. Ms Kossy profiles several individuals through their writings, some of which straddle the line between genius and insanity. One such gentleman profiled believes in a movement of "voluntary human extinction", making him a sort of Charles Darwin in reverse, giving the planet back to the lesser species, since he feels we have blown it. Others profiled range from hatemongers to comical figures.

However, as Kossy points out quite eloquently, one century's "kook" could become another century's visionary, as in the case of Alfred Wegener, who first postulated the theorum of continental drift.
