You are the reason I am. You are all my reasons

 Nash: Thank you. I've always believed in numbers and the equations and logics that lead to reason. 
But after a lifetime of such pursuits, I ask, "What truly is logic? Who decides reason?" 
My quest has taken me through the physical, the metaphysical, the delusional -- and back. 
And I have made the most important discovery of my career, the most important discovery of my life: It is only in the mysterious equations of love that any logic or reasons can be found. 
I'm only here tonight because of you [his wife, Alicia]. 
You are the reason I am. You are all my reasons. 
Thank you.
(我一直相信数字，方程式，逻辑推理，一定有他的理由。但是当我回过头想，我问我自己，什么是正确的逻辑推理？谁决定的？我探索这个问题，从肉体上到精神上，到幻觉上再回来。然后我发现了，我生涯最重要的事，这是我一生最重大的事情，就是爱是一种特殊的感觉，是没有办法靠正常逻辑去推断的。后来我清醒了，这都是你的功劳，你是我活下去的理由，你是我的全部)
