Despite its techno-talk,
Star Trek↗ and The Next Generation were, at bottom, shows about the nature and meaning of being human. The endless parade of evil aliens and perverted civilizations — from the
bellicose Klingons to the
pernicious Borg, with their hivelike collective consciousness — was always contrasted to the civilized humans on board the Enterprise. The most popular characters were the nonhuman ones — Spock, the “logical” Vulcan, and Data, the soulless android — precisely because they were constantly being confronted with the human qualities they lacked: the emotions they either scorned (in Spock's case) or craved (in Data's).
