A clone of Einstein wouldn't be stupid, but he wouldn't necessarily be any genius, either.

Already for thirty-five years he had not stopped talking and almost nothing of fundamental value had emerged.

There is no firm reason to anticipate that the intellectual capacities of peoples geographically separated in their evolution should prove to have evolved identically. Our wanting to reserve equal powers of reason as some universal heritage of humanity will not be enough to make it so.

Some think there is something wrong about enhancing people.

Whenever you interview fat people, you feel bad, because you know you're not going to hire them.

No one may have the guts to say this, but if we could make better human beings by knowing how to add genes, why shouldn't we?

Ultimately, we'll help the people we discriminate against if we try to understand more about them; genetics will lead to a world where there is a sympathy for the underdog.
