Managers are not confronted with problems that are independent of each other, but with dynamic situations that consist of complex systems of changing problems that interact with each other. I call such situations messes. Problems are extracted from messes by analysis. Managers do not solve problems, they manage messes.

The effectiveness of any model used to describe and understand behavior of a particular system as a whole ultimately depends on the degree to which that model accurately represents that system. Nevertheless, there have been and are situations in which application of deterministic or animate models to social systems have produced useful results for a short period of time. However, in a longer run,

such mismatches usually result in less than desirable results because critical aspects of the social systems were omitted in the less complex model that was used.

Where the division of property and labour is incomplete there is little division of classes and of power. Until societies are tried by the complex problems of civilisation they may escape despotism, as societies that are undisturbed by religious diversity avoid persecution.

[Television, radio, and magazines] are so designed as to make thinking seem unnecessary (though this is only an appearance). The packaging of intellectual positions and views is one of the most active enterprises of some of the best minds of our day. The viewer of television, the listener to radio, the reader of magazines, is presented with a whole complex of elements—all the way from ingenious

rhetoric to carefully selected data and statistics—to make it easy for him to make up his own mind” with the minimum of difficulty and effort. But the packaging is often done so effectively that the viewer, listener, or reader does not make up his own mind at all. Instead, he inserts a packaged opinion into his mind, somewhat like inserting a cassette into a cassette player. He then pushes a

button and plays back” the opinion whenever it seems appropriate to do so. He has performed acceptably without having had to think.

The point of a brain is that it's not one huge neural network with feedback, it has up to 50 to 60 identified areas, all of which have feedback and all of which are capable of knowledge storage. We've got a complex system and, within this complex system, we can start discovering what the mechanisms that support deliberation are. Consciousness must come out of these interactions.

Let's discuss the world. To answer the question, "is globalisation possible without God", the simple answer is "yes". Globalisation is after all itself a code word, a mask, for not using the C-word, capitalism. Globalisation is basically the latest phase of expanding capitalism. This not something which is neutral, this is a capitalism that has its rules: it has its economic rules, it has its

political rules, it has its cultural rules and it has its military rules. It is a system. At the heart of this system is the United States of America, the world's only existing empire today. The first time in the history of humanity that you have just had a single empire, so dominant, whose military budget is higher than the military budgets of the next 15 countries put together, and whose

military-industrial complex itself is the eleventh largest economic entity in the world. This is the reality we live in, and this is the reality which confronts us in different ways.

There are no buildings that have been built by chance, remote from the human society where they have grown and its needs, hopes and understandings, even as there are no arbitrary lines and motiveless forms in the work of the masons. The life and existence of every great, beautiful and useful building, as well as its relation to the place where it has been built, often bears within itself complex

and mysterious drama and history.

A trial in Westminster Hall, in July last, at a large expence, was the consequence; when, solely by not describing so fully and accurately the nature of his last complex machines as was strictly by law required, a verdict was found against him. Had he been at all aware of the consequences of such omission, he certainly would have been more careful and circumspect in his description. It cannot be

supposed that he meant a fraud on his country: it is on the contrary, most evident that he was anxiously desirous of preserving to his native country the full benefit of his inventions. Yet he cannot but lament, that the advantages resulting from his own exertion and abilities alone, should be wrested from him by those who have no pretension to merit; that they should be permitted to rob him of

his inventions before the expiration of the reasonable period of fourteen years, merely because he has unfortunately omitted to point out all the minutiae of his complicated machines. In short, Mr. Arkwright has chosen a subject in manufactures (that of spinning) of all others the most general, the most interesting, and the most difficult. He has, after near twenty years unparalleled diligence and

application, by the force of natural genius, and an unbounded invention, (excellencies seldom united) brought to perfection machines on principles as new in theory, as they are regular and perfect in practice. He has induced men of property to engage with him to a large amount; from his important inventions united, he has produced better goods, of their different kinds, than were ever before

produced in this country; and finally, he has established a business that already employs upwards of five thousand persons, and a capital, on the whole, of not less than £200,000, a business of the utmost importance and benefit to this kingdom.

As we begin to understand complex systems, we begin to understand that we’re part of an ever-changing, interlocking, non-linear, kaleidoscopic world.

The inductive-reasoning system I have described above consists of a multitude of elements” in the form of belief-models or hypotheses that adapt to the aggregate environment they jointly create. Thus it qualifies as an adaptive complex system. After some initial learning time, the hypotheses or mental models in use are mutually co-adapted. Thus we can think of a consistent set of mental models

as a set of hypotheses that work well with each other under some criterion—that have a high degree of mutual adaptedness. Sometimes there is a unique such set, it corresponds to a standard rational expectations equilibrium, and beliefs gravitate into it. More often there is a high, possibly very high, multiplicity of such sets. In this case we might expect inductive reasoning systems in the

economy—whether in stock-market speculating, in negotiating, in poker games, in oligopoly pricing, in positioning products in the market—to cycle through or temporarily lock into psychological patterns that may be non-recurrent, path-dependent, and increasingly complicated. The possibilities are rich.
