Star Trek: Every Vulcan Ability You Need To Know

8. Controlling Emotions

As mentioned earlier, when the philosopher, Surak, introduced the Vulcan society to his belief system of logic and emotional suppression, the species saw it as the only way to save the Vulcan people from themselves.

Naturally, Vulcans have much more intense emotions than most humanoid species. Their violent nature combined with their impressive physical and mental abilities led to a great many wars that devastated the planet for generations. So, although Vulcans may seem completely robotic, this is all just a façade that they maintain to avoid allowing their emotions to control them.

Vulcans work their whole lives to eradicate their emotions, though subtle hints of them remain deep in their minds. Without completing the Vulcan ritual known as Kolinahr, which Spock was never able to do, a Vulcan is still capable of emotional outbursts when dealing with extreme stress.

There have, however, been some Vulcans who've embraced their emotions fully, rejecting the Vulcan way of life, such as Spock's half-brother, Sybok.
