Spock and Data in “Unfinished Business”

Spock

Fascinating. You have an efficient intellect, superior physical skills, no emotional impediments. There are Vulcans who aspire all their lives to achieve what you've been given by design.

Data

You are half human?

Spock

Yes.

Data

Yet you have chosen a Vulcan way of life?

Spock

I have.

Data

In effect, you have abandoned what I have sought all my life.
