Vulcan
From Star Trek: Theurgy Wiki
The Vulcans were a stoic, rational people. Widely claimed to be emotionless, in truth the Vulcans felt deeply and intensely, to their own detriment. Their stoicism came from a culture of logic and self-discipline, where emotions were analyzed and dissected to rob them of their potency so that they could not overwhelm or control the individual. Vulcans embraced science and reason, but their lives were not purely devoted to logic: they also had a deeply philosophical side, with art and music as vital to their culture as logic. They were also intensely private people, with many aspects of their culture — such as the rites of Pon Farr — which were not discussed amongst outsiders.
Personality
Vulcans exalted logic over emotion and usually repressed or sublimated emotions in their daily behavior. Vulcans who dealt with non-Vulcans on a regular basis often maintained an almost glacial calm, possibly as self-defense against so much unguarded feeling. Among themselves, however, Vulcans usually seemed more relaxed; Vulcan ambassadors often cultivated a kind of distant good humor and politesse. Even Vulcan ambassadors, however, had trouble predicting or depending upon the behavior of more emotional species.
