I have faith in the innate goodness of people.

Most of the evidence is invisible, because it takes the form of things that didn't happen.

Nobody took the bike. Four hundred drivers made room for you today and none of them mentioned it. The parcel sat on the step for six hours.

Cruelty is louder and better reported, so the ledger looks worse than it is.

Faith here isn't optimism about human nature in general. It's the working assumption that the stranger walking behind you at night is almost certainly just walking home — which is true, and which is what makes leaving the house possible at all.
