## Key lines

> Suppose⁠—this is just speculation⁠—that we could control heredity and environment. Then we could recreate the same individual at will.

Kesserich speculates that if we could control genetics and surroundings, we could make an exact copy of a person.

_This introduces the central philosophical and scientific question of the chapter._

> Newman tells about a pair of identical twins separated from birth, unaware of each other’s existence. They met by accident when they were twenty-one. Each was a telephone repairman. Each had a wife the same age. Each had a baby son. And each had a fox terrier called ‘Trixie.’

Kesserich cites a case of identical twins raised apart who ended up with remarkably similar lives, suggesting environment may be less influential than thought.

_This anecdote supports Kesserich's argument about the power of heredity._
