内容简介：Golan Trevize, former Councilman of the First Foundation, has chosen the future, and it is Gaia. A superorganism, Gaia is a holistic planet with a common consciousness so intensely united that every dewdrop, every pebble, every being, can speak for all—and feel for all. It is a realm in which privacy is not only undesirable, it is incomprehensible.
