Spock in “Unfinished Business”

Spock

The reason for my coming here has never been more clear. The union of the Vulcan and the Romulan people will never be achieved by politics or diplomacy, but it will be achieved. The answer has been here before us all along. An inexorable evolution toward a Vulcan philosophy has already begun. Like the first Vulcans, these people are struggling through a new enlightenment, and it may take decades or even centuries for them to reach it. But they will reach it, and I must help.
