Star Trek: The Next Generation1987

Ambassador Spock:
I always had a different vision than my father, the ability to see beyond pure logic. He considered it weak. But I have discovered it to be a source of extraordinary strength. Sarek would have seen this mission of reunification as a fool's errand. Somehow I think it is not. Logic cannot explain why, I only know that I must pursue this.

Captain Jean-Luc Picard:
Even if it leads you into a Romulan trap?

Ambassador Spock:
If the Romulans do have an ulterior motive, it is in the best interests of all concerned that we determine what it is. So... I will play the role that they would have me play.
