V'tosh ka'tur

The term "V'tosh ka'tur" referred to "Vulcans without logic." In Vulcan, it was used by elders to refer to anyone who disagreed with ancestral teachings. Around 2143, a group of these Vulcans left their homeworld aboard the starship Vahklas. The crew of encountered the Vahklas in 2151 while en route to the Arachnid Nebula. Their ship's captain, Tavin, requested some assistance in the repair of their propulsion and life support.

In truth, these Vulcans hadn't abandoned their logic but had simply learned to exist without the need to continually suppress their emotions. They still believed that logic was an essential part of Vulcan existence, but that it had to complement emotions, not exclude them. After eight years of experimentation, they claimed to have finally managed to find a balance between the two, through constant discipline and meditation.
