"The Life Force is also the Heautontimoroumenos, the Self-Tortured."
The Gaean speaker defines the term as soon as she uses it but it is convenient to be able to Google for further elucidation. (An unusual term used in another series, the Time Patrol, was "psychopomp.")
Gaeanity is one of many future philosophies imagined by Anderson. Characteristically, he shows it as neither simply good nor simply bad. Gaean meditation is not trance but merging of being with world, thus opening senses, heightening perceptions and, in one case, hearing approaching strangers who are still afar. (p. 246)
Iern, conversing with the Gaean, comments that ruling classes favor Gaeanity because it encourages submission among restless populations:
"...never mind liberty or traditional rights, just retreat into your head. Or it can be useful in marshaling forces against a rival...as I found out." (p. 258)
The philosophical is also the political. Gaeans address all life on Earth as "Gaea, Great All-Mother..." (p. 102) and regard human beings as "organelles," another word that might need a dictionary. (p. 84)
For me, Gaeanity in and of itself, not just its ideological/political applications, is shown to be a negative force by the following passage. Of someone seeking fissionables, a Gaean directive states:
" - whoever is responsible for this must be found out and annihilated. You are the defensive cells of Gaea. Through you, now, acts the Life Force." (p. 183)
This is green fascism.
