Hallemeier. Fancy me being knifed. (Looks at each. Then speaks) Why are you so quiet, you fools? (Steps down) Speak, can’t you?

Alquist. And who is to blame for all this?

Hallemeier. Nobody is to blame except the Robots.

Alquist. No, it is we are to blame. You, Domin, myself—all of us. For our own selfish ends, for profit, for progress, we have destroyed mankind. Now we’ll burst with all our greatness.

Hallemeier. Rubbish, man. Mankind can’t be wiped out so easily.

Alquist. It’s our fault. It’s our fault. (Rises, coming R. of Gall.)

Dr. Gall. No! I’m to blame for this, for everything that’s happened. (He leaves the window and comes down to end of couch.)

Fabry. You, Gall?

Dr. Gall. I changed the Robots.

Busman. What’s that?
