What truly is logic?

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 [wife, Alicia].

You are the reason I am.

You are all my reasons.

Thank you.
