Quotations

"Most problems cannot be solved. Most problems can only be survived. And one survives problems by making them irrelevant because of success. It's amazing how many minor ills the healthy body can stand without any trouble. One focuses on success, especially unexpected success, and runs with it."
Peter F. Drucker in P.F. Drucker, P.M. Senge, F. Hesselbein, "Leading in a Time of Change", Jossey-Bass, San Francisco, 2001.

"We spend a lot of our time fixing unimportant problems." Peter Senge, in P.F. Drucker, P.M. Senge, F. Hesselbein, "Leading in a Time of Change", Jossey-Bass, San Francisco, 2001.

"A prime requirement of scientific finds is that they shall be communicable to others." J.P. Guilford, Fundamental Statistics in Psychology and Education. New York: McGraw-Hill, 1956.

"First find your basic principle, then settle how it is to be applied to your subject - that surely is the only way of putting truth into practice. History has its value whether as a guide or a warning, and we should be foolish indeed to underrate it: but unless its facts are related to a truth which illuminates them, they possess no more than an antiquarian interest."
W. J. Phythian-Adams in "The Way of At-one-ment", London: SCM, 1944.

Oversimplification

"The invention of deliberately oversimplified theories is one of the major techniques of science, particularly of the 'exact' sciences, which make extensive use of mathematical analysis. If a biophysicist can usefully employ simplified models of the cell and the cosmologist simplified models of the universe then we can reasonably expect that simplified games may prove to be useful models for more complicated conflicts." Attributed to John Williams, The Compleat Strategyst, New York, McGraw Hill, 1954.

And we can then also reasonably expect that simplified representations of complex interpersonal relationships, or of attitudes, beliefs, opinions, abilities, performances, etc., may also prove useful, as has in fact been repeatedly demonstrated in the history of Rasch measurement.
William P. Fisher, Jr.
