Logic is the principle of reasoned thinking.
History and specificsEdit
The Vulcan people adopted logic as a way of life and, deeming emotions illogical, suppressed theirs. The Vulcans of the lost colony of the Last-of-all-Cities left the planet Vulcan before the spread of logic among their people and when they were rediscovered were disgusted by what had become of their civilization. They planned to hijack the USS Enterprise and return to Vulcan as conquerors. Spock could not understand this, noting how illogical their violence was given they had the capacity to construct an impulse engine themselves.
