Neo-Transcendentalism

From Memory Alpha, the free Star Trek reference.

Neo-Transcendentalism was a philosophical movement on Earth in the late 21st or early 22nd century, founded by Liam Dieghan. Adherents of the philosophy advocated a return to less technological driven lifestyles with an emphasis on self-reliance and nature.

The SS Mariposa, a colony ship launched from Earth in 2123, carried many Neo-Transcendentalists who eventually settled on Bringloid V. (TNG: "Up The Long Ladder")

It should be noted that this form of Neo-Transcendentalism should not necessarily be confused with the Neo-Transcendentalist movements of our very own 20th century (see: external link).
