they are inside, part of the man himself, there's nothing you can do.
Nothing. You can save a person from the world, but not from himself.
That's where the devil comes in. I see it now. I believe in the devil.

MARGARET

Oh! But _Arthur_....

ROGER

I know you think I'm a brute for speaking of Arthur in connection with the
devil, but it wasn't the old-fashioned devil I meant. I meant the devil of
unfitness. Arthur wasn't _fit_. He had every chance. We can't get away
from what life is. Life shoves people to the wall every day. I've had to
fight hard myself. I admit things aren't fair all round, but Arthur had
his chance, two or three chances, and he just--dropped out. He couldn't
_survive_. And it seems to me that for those who loved him it may be a
good thing after all that he didn't have to go on.

MARGARET

Roger! You shan't say that! You shan't!

ROGER

I don't want to, Margaret, but that's what life itself says. We can't get
behind life. We can't beat evolution and the law of survival.
