We have also come to realize that no problem ever exists in complete isolation. Every problem interacts with other problems and is therefore part of … - Russell L. Ackoff

The Machine Age’s commitment to cause and effect was the source of many dilemmas, including the one involving free will. At the turn of the century the American philosopher E.A. Singer, Jr., showed that science had, in effect, been cheating. It was using two different relationships but calling both cause and effect. He pointed out, for example, that acorns do not cause oaks because they are not sufficient, even though they are necessary, for oaks. An acorn thrown into the ocean, or planted in the desert or an Arctic ice cap does not yield an oak. To call the relationship between an acorn and an oak ‘probabilistic’ or ‘non deterministic causality,’ as many scientists did, was cheating because it is not possible to have a probability other than 1.0 associated with a cause; a cause completely determines its effect. Therefore, Singer chose to call this relationship ‘producer-product’ and to differentiate it from cause-effect.

I began graduate work in the philosophy of sciences at the University of Pennsylvania in 1941 where I came under the influence of the “grand old man” of the department, the eminent philosopher E.A. Singer, Jr. Because of the informality of the department he created I began to collaborate with two younger members of the faculty, both of whom were former students of Singer, Thomas A. Cown and C. West Churchman. Three aspects of Singer's philosophy had a particularly strong influence on me. First, that the practice of philosophy, its application, was necessary for the development of philosophy itself. Second, that effective work on “real” problems required an interdisciplinary approach. Third, that the social area needed more work than any of the other domains of science and that this was the most difficult. We developed a concept of a research group that would enable us to practice philosophy in the social domain by dealing with real problems. The organization we designed was called “The Institute of Experimental Method.” With the participation of a number of other graduate students in philosophy and a few other members of the faculty we started this institute on a completely informal basis.

A great deal of study has been directed to denning 'best decisions,' particularly since the pioneering work of mathematical statisticians (such as Wald), of mathematicians (such as von Neumann), of economists (such as Arrow)... The main effect of this development on the practice of OR has been the growing realization that there are decision objectives other than maximizing expected return and minimizing maximum loss. That is, in many practical situations there are criteria of optimality that are more appropriate than these two mentioned.
