Moore [to Kreizler]: Please tell me you didn't come here just to frighten my grandmother.
Grandmother Moore: I'm not the least bit frightened by these psychopaths.

Sara: I shot Captain Connor, sir.
Roosevelt: You've always had the courage to do what needs to be done. Your father would be proud of you.

Turn me down, by all means. But don't pretend I have no feelings for you.

Moore [to Sara]

I ain't asking for your charity. I'm just asking that you don't cross the street every time you see me.

Esther [to Marcus]

If I still drank, old man, I'd rather drink alone than with you.

Moore [to Astor]

I could take your eyes, but I want you to see.

Beecham [to Kreizler]

Sara: The last thing an honest politician can expect is gratitude, if I can quote you. We know his name, we know where he lives. We're close, sir.
Roosevelt: Not close enough.

Sara: You're not to blame, John.
Moore: Of course I am. God put him in my way, and I failed him like everyone else.

I've made my life's work the study of the human mind. And now my own mind deceives me. I have cause to hate God for what he did to her, and yet I find myself believing in him, humbled by his awful mystery.

Kreizler [to Sara]

Sara: I've learned from you. We can either let it haunt us for the rest of our lives, or we can accept it, and use the memory of our pain to help others.
Kreizler: I'm not sure the choice is ever entirely in our hands.
Sara: I disagree. If it weren't, we'd all be murderers.

Roosevelt: What matters is you stopped a monster.
Kreizler: We set out to stop a monster, but all we found was a wounded child.

Kreizler: In every way, a perfectly normal and healthy brain.
Moore: What does that prove? That he wasn't insane?
Kreizler: It proves we don't know anything. God works between the lines.

The Alienist Quotes

Marcus: Do you know the difference between capitalism and socialism?
Lucius: No.
Marcus: In capitalism, man exploits man. In socialism, it's the other way around.

You are not alone in your sorrow, and there's no shame in grieving for those you love.

Roosevelt [to Kreizler]
