"The rudest numerical scales, such as that by which mineralogists
distinguish different degrees of hardness, are found useful. The mere
counting of pistils and stamens sufficed to bring botany out of total chaos
into some kind of form. It is not, however, so much from counting as from
measuring, not so much from the conception of number as from that of a
continuous quantity, that the advantage of mathematical treatment comes.
Number, after all, only serves to pin us down to a precision in out thoughts
which, however beneficial, can seldom lead to lofty conceptions, and frequently
descends to pettiness."
Charles Peirce (1878) in The Doctrine of Chances

"...one must expect that some subjects will do their task in a perfunctory or careless manner... [or] fail to understand the experiment or fail to read the ...instructions carefully... It has seemed desirable, therefore, to set up some criterion by which we could identify those individual records which were so inconsistent that they should be eliminated from our calculations."
