Surak's ideas were that all Vulcans should suppress emotions, for the safety of the species. Before him, Vulcans were dangerously raging, emotional, war-like and religiously fanatical, to the point that it could have threatened the continuation of their society and species. Then, around the 4th century BC, he created a system revolving around these ideas, intended to create a peaceful society. Some Vulcans disagreed, unfortunately, causing a war to break out. The two sides separated, causing the emotional ones to become Romulans and the logical ones to become what is referred to as modern-day Vulcans. Vulcans still possess and experience emotions, but make great efforts to keep them from being expressed or controlling their behavior. They occasionally have mental breakdowns. Only those who follow the discipline of kolinahr have completely purged all emotions from their minds. Spock, in Star Trek: The Motion Picture, attempts to achieve kolinahr, but ultimately fails to do so.
