Kenneth E. Boulding Quotes

It is clear that the building of models is not a purely mechanical process but requires skill of a high order – not merely mathematical skill but a sensitivity to the relative importance of different factors and a critical, almost an artistic, faculty in the selection of behaviour equations which are reasonable, tentative hypotheses in explaining the behaviour of actual economies.

Knowledge exists in minds, not in books. Before what has been found can be used by practitioners, someone must organize it, integrate it, extract the message

If a totally new image is to come into being however, there must be sensitivity to internal messages, the image itself must be sensitive to change, must be unstable, and it must include a value image which places high value on trials, experiments, and the trying of new things.

Physicists can only talk to other physicists and economists to economists... sociologists often cannot even understand each other.

A second possible approach to general systems theory is through the arrangement of theoretical systems and constructs in a hierarchy of complexity, roughly corresponding to the complexity of the "individuals" of the various empirical fields... leading towards a "system of systems."… I suggest below a possible arrangement of "levels" of theoretical discourse.

The world moves into the future as a result of decisions, not as a result of plans. Plans are significant only insofar as they affect decisions.

One reason why the progressive state is 'cheerful' is that social conflict is diminished by it.

Any attempt to reduce the complex properties of biological organisms or of nervous systems or of human brains to simple physical and chemical systems is foolish.

We cannot walk befor we toddle,
Though we may toddle far too long,
If we embrace a lovely Model
That is consistent, clear, and wrong.
- Experts from "Notes from Wooods Hole", unpublished, 1976.

Prediction of the future is possible only in systems that have stable parameters like celestial mechanics. The only reason why prediction is so successful in celestial mechanics is that the evolution of the solar system has ground to a halt in what is essentially a dynamic equilibrium with stable parameters. Evolutionary systems, however, by their very nature have unstable parameters. They are disequilibrium systems and in such systems our power of prediction, though not zero, is very limited because of the unpredictability of the parameters themselves. If, of course, it were possible to predict the change in the parameters, then there would be other parameters which were unchanged, but the search for ultimately stable parameters in evolutionary systems is futile, for they probably do not exist... Social systems have Heisenberg principles all over the place, for we cannot predict the future without changing it.

Let me first explain, then, what I mean by moral and moral science. A moral or ethical proposition, is a statement about a rank order of preference among alternatives, which is intended to apply to more than one person. A preference which applies to one person only is a taste. Statements of this kind are often called "value judgments." If someone says, "I prefer A to B," this is a personal value judgment, or a taste. If he says, "A is better than B," there is an implication that he expects other people to prefer A to B also, as well as himself. A moral proposition then is a "common value".

[The law of evolution states that] complexity increases in terms of differentiation and structure.

Thus we seem to be on the verge of an expansion of welfare economics into something like a social science of ethics and politics: what was intended to be a mere porch to ethics is either the whole house or nothing at all. In so laying down its life welfare economics may be able to contribute some of its insights and analytical methods to a much broader evaluative analysis of the whole social process.

Equilibrium is a figment of the human imagination.

One advantage of exhibiting a hierarchy of systems in this way is that it gives us some idea of the present gaps in both theoretical and empirical knowledge. Adequate theoretical models extend up to about the fourth level, and not much beyond. Empirical knowledge is deficient at practically all levels.
