Quote context

[...]

- You can't just throw your career away because of a sentimental whim.

- But I'm not throwing my career away.

- But if Haislip feels that way, so will every other law firm in town.

- I'm sure they will.

- Then I'll open my own office.

- And what kind of cases will you get?

- Oh, probably a lot of people like Kris that are being pushed around. That's the only fun in law anyway.

- I promise you, if you believe in me and have faith in me, everything will... You don't have any faith in me, do you?

- It's not a question of faith. It's just common sense.

- Faith is believing in things when common sense tells you not to.

- Don't you see? It's not just Kris that's on trial. It's everything he stands for. It's kindness and joy and love and all the other intangibles.

- Oh, Fred! You're talking like a child! You're living in a realistic world. And those lovely intangibles of yours are attractive, but not worth very much.

- You don't get ahead that way.

- That all depends on what you call getting ahead. Evidently, you and I have different definitions.
