Star Trek: 10 Biggest Examples Of Vulcans Being Illogical

10. Reverting To Your Ancestors

Before starting, it has to be said that several illogical decisions made by Vulcans were done so due to circumstances out of their control. Spock put pleasure above all else thanks to Omicron Ceti III's native spores for example, and T'Pol became enraged by exposure to Trellium-D. Despite these however, there is one moment of Vulcan illogic that is itself, rather illogical. Having travelled back to the Ice Age of the planet Sarpeidon, Spock reverts to a highly emotional, pre-logic Vulcan of their current era, some 5,000 years in the past. While his anger towards McCoy and love for Zarabeth certainly make for some dramatic conflict, the writers conveniently side-stepped the fact that when you think about it, this doesn't actually make any sense. Certainly Vulcans 4,700 years ago were barbaric, but there is no logical reason to assume that merely by sharing the same point in time (still countless light years away from Vulcan itself) Spock's physiology or philosophy would revert back to a point from before he was born. With Star Trek now a massive phenomenon, it is easy to forget that it all began with what was just one of many larger than life action-oriented TV series. Today's series and writers pay far more attention to their verisimilitude however, and with a keener attention to detail, illogical decisions comes at no-ones fault but the Vulcans themselves.
