How about history? The internal combustion engine on which we now rely simply cannot be viewed in isolation without any thought given to what had been before it. It is not as if it had not existed we would all dwell in immaculate urban pedestrianized New Yorker-style cartoon locales where everyone is cycling and doing yoga and going to therapy.

I didn't think it would be fair talking with her merely for the sake of just talking - even if doing that might in some ways perhaps have been usefully self-promotional.
