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 ….

This is perhaps the most important book on evolutionary genetics ever written.

I believe that no one who is familiar, either with mathematical advances in other fields, or with the range of special biological conditions to be co….

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..

More attention to the History of Science is needed, as much by scientists as by historians, and especially by biologists, and this should mean a deli….

No isolated experiment, however significant in itself, can suffice for the experimental demonstration of any natural phenomenon; for the "one chance ….

Modern statisticians are familiar with the notion that any finite body of data contains only a limited amount of information on any point under exami….

The statistician cannot excuse himself from the duty of getting his head clear on the principles of scientific inference, but equally no other thinki….

If one in twenty does not seem high enough odds, we may, if we prefer it, draw the line at one in fifty (the 2 per cent. point), or one in a hundred ….

... the actual and physical conduct of an experiment must govern the statistical procedure of its interpretation..

... no scientific worker has a fixed level of significance at which from year to year, and in all circumstances, he rejects hypotheses; he rather giv….

The million, million, million ... to one chance happens once in a million, million, million ... times no matter how surprised we may be that it resul….

The neutral zone of selective advantage in the neighbourhood of zero is thus so narrow that changes in the environment, and in the genetic constituti….

In scientific subjects, the natural remedy for dogmatism has been found in research..

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

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 ….

Although no explanation can be expected to be satisfactory, it remains a possibility among others that Mendel was deceived by some assistant who knew….

Natural selection is not evolution..

I believe sanity and realism can be restored to the teaching of Mathematical Statistics most easily and directly by entrusting such teaching largely ….

We can set no limit to human potentialities; all that is best in man can be bettered; it is not a question of producing a highly efficient machine, .….

A book that I rate only second in importance in evolution theory to Darwin 's Origin (this as joined with its supplement Of Man), and also rate as un….
