Quantitative vs. Qualitative

By Steve Draper,   Department of Psychology,   University of Glasgow.

My real position is that Quantitative vs. Qualitative is not quite the right way of posing the issue (see here).

However here's a great quote anyway:
"In physical science the first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods for measuring some quality connected with it. I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the state of Science, whatever the matter may be."
Lord Kelvin, PLA, vol. 1, "Electrical Units of Measurement", 1883-05-03
