To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.
Natural selection is not evolution.
Natural selection is a mechanism for generating an exceedingly high degree of improbability.
The tendency of modern scientific teaching is to neglect the great books, to lay far too much stress upon relatively unimportant modern work, and to present masses of detail of doubtful truth and questionable weight in such a way as to obscure principles.
The academic mind, as we know, is sometimes capable of assuming an aggressive attitude. The official mind, on the contrary, is and has to be, expert in the art of self- defence.
We may consequently state the fundamental theorem of Natural Selection in the form : The rate of increase in fitness of any organism at any time is equal to its genetic variance in fitness at that time.
The million, million, million... to one chance happens once in a million, million, million... times no matter how surprised we may be that it results in us.
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.
Faith Is Not Credulity.
There is, then, in this analysis of variance no indication of any other than innate and heritable factors at work.
No practical biologist interested in sexual reproduction would be led to work out the detailed consequences experienced by organisms having three or more sexes; yet what else should he do if he wishes to understand why the sexes are, in fact, always two?
We have the duty of formulating, of summarizing, and of communicating our conclusions, in intelligible form, in recognition of the right of other free minds to utilize them in making their own decisions.
Fairly large print is a real antidote to stiff reading.
No efforts of mine could avail to make the book easy reading.
The analysis of variance is not a mathematical theorem, but rather a convenient method of arranging the arithmetic.
