We just don't know them yet. The word yet, for Wilson, is a hedge on overreaching, a confession of present ignorance, an expression of confidence in future understanding. And, for Berry, the opposite. Yet is Wilson staking a claim on things he cannot know and will never know. Yet is a denial of limits, the squeak of hubris, the antithesis of humility.
Life is a miracle, never, ever to be reduced to chemistry and physics.
There is simply no ''not yet'' about it. Yet has consequences, Berry states. People exploit machines. They defend what they love. And no one loves a machine.
