The more highly adapted an organism becomes, the less adaptable it is to any new change.

The analysis of variance is not a mathematical theorem, but rather a convenient method of arranging the arithmetic.

Natural selection is a mechanism for generating an exceedingly high degree of improbability.

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

Modern statisticians are familiar with the notion that any finite body of data contains only a limited amount of information on any point under examination; that this limit is set by the nature of the data themselves, and cannot be increased by any amount of ingenuity expended in their statistical examination: that the statistician's task, in fact, is limited to the extraction of the whole of the available information on any particular issue.

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.

I believe sanity and realism can be restored to the teaching of Mathematical Statistics most easily and directly by entrusting such teaching largely to men and women who have had personal experience of research in the Natural Sciences.
