I prefer this exchange from Star Trek Voyager: Harry Kim : Seven, you’ve been around humans for a while now. What do you think about… love? Seven of Nine : We’re scanning for microfractures. I don’t see the relevance. Harry Kim : Just curious. Seven of Nine : Parental love, romantic love, affection between friends – specify. Harry Kim : Romantic love. Seven of Nine : An attraction based on sexual desire, one that facilitates procreation. Harry Kim : I guess I’m asking the wrong person. Seven of Nine : Not at all. The Borg have referenced this condition in over 6,000 assimilated species. Harry Kim : Condition? You make it sound like a disease. Seven of Nine : Physiologically, it bears a striking similarity to disease. A series of biochemical responses that trigger an emotional cascade, impairing normal functioning. Harry Kim : Forget it. I think it is much more accurate.
