Quote context

[...]

- We must create from the beginning. We must build up our own creature. Build it up from nothing.

- From what? What on earth are you talking about?

- Forget the whole. Now we must take the parts limbs, organs, and then we must build.

- Build what?

- The most complex thing known to man: Man himself.

- We must create a human being, a man with perfect physique, the hands of an artist, with a matured brain of a genius.

- We can do it. Don't you see?

- No, I don't.

- What you're saying is nonsense, a revolt against nature. Such a thing could only end in evil.

- Come, what's the matter with you? You haven't shown any scruples up to now.

- And as for revolting against nature, haven't we done so already and succeeded?

- Isn't the thing that's dead supposed to be dead for all time? Yet we brought it back to life.
