The best causes tend to attract to their support the worst arguments, which seems to be equally true in the intellectual and in the moral sense.

The best time to plan an experiment is after you've done it.

No aphorism is more frequently repeated in connection with field trials, than that we must ask Nature few questions, or, ideally, one question, at a time.
