Machines as simple as thermostats can be said to have beliefs, and having beliefs seems to be a characteristic of most machines capable of problem solving performance. However, the machines mankind has so far found it useful to construct rarely have beliefs about beliefs, although such beliefs will be needed by computer programs that reason about what knowledge they lack and where to get it. Mental qualities peculiar to human-like motivational structures, such as love and hate, will not be required for intelligent behavior, but we could probably program computers to exhibit them if we wanted to, because our common sense notions about them translate readily into certain program and data structures. Still other mental qualities, e. g. humor and appreciation of beauty, seem much harder to model.

The Age of Empty Freedom ... does not know that man must first through labour, industry, and art, learn how to know; but it has a certain fixed standard for all conceptions, and an established Common Sense of Mankind always ready and at hand, innate within itself and there present without trouble on its part;-and those conceptions and this Common Sense are to it the measure of the efficient and the real. It has this great advantage over the Age of Science, that it knows all things without having learned anything; and can pass judgment upon whatever comes before it at once and without hesitation,-without needing any preliminary evidence:-'That which I do not immediately comprehend by the conceptions which dwell within me, is nothing,'-says Empty Freedom.

Data management housekeeping is not the only problem to plague oversimplified approaches to high speed computation. The physical problems which are of practical interest tend to have rather significant complications. Examples of these complications are as follows: boundaries are likely to be irregular; interiors are likely to be inhomogeneous; computations required may be dependent on the states of the variables at each point; propagation rates of different physical effects may be quite different; the rate of convergence, or convergence at all, may be strongly dependent on sweeping through the array along different axes on succeeding passes; etc. The effect of each of these complications is very severe on any computer organization based on geometrically related processors in a paralleled processing system.

Amid all the triumphs of our civilization - yes, and amid the crushing problems of overpopulation too - it is sad to reflect how many millions of people suffer from increasing loneliness and isolation. Our serving-man will be a boon to them; he will always answer, and the most vapid conversation cannot bore him.
For the future, we plan more models, male and female - some of them without the limitations of this first one, I promise you! - of more advanced design, true bio-electronic beings.
Not only will they possess their own computer, capable of individual programming; they will be linked to the World Data Network. Thus everyone will be able to enjoy the equivalent of an Einstein in their own homes. Personal isolation will then be banished forever!

The chief distinction in the intellectual powers of the two sexes is shewn by man attaining to a higher eminence, in whatever he takes up, than woman can attain - whether requiring deep thought, reason, or imagination, or merely the use of the senses and hands. If two lists were made of the most eminent men and women in poetry, painting, sculpture, music, - comprising composition and performance, history, science, and philosophy, with half-a-dozen names under each subject, the two lists would not bear comparison. We may also infer, from the law of the deviation of averages, so well illustrated by Mr. Galton, in his work on 'Hereditary Genius,' that if men are capable of decided eminence over women in many subjects, the average standard of mental power in man must be above that of woman. ... Thus man has ultimately become superior to woman.

General systems theory, in a sense, is no news at all, as Von Foerster found out when he attempted to organize a conference of general systems people and anthropologists. In a sense, the situation is comparable to that found by the Committee for the Study of Mankind, in which a committee that included Robert Redfidd tried to get each discipline to consider its relationship to the concept of Mankind. Anthropologists replied, "we are related already," and so they were. Something similar may be said of attempts to date in mathematical anthropology. The kind of information that a computer program can finally provide, on a level of a particular culture, is simply a reflection of how detailed field work has been done, and to the careful field worker, on kinship, for example, it provides no illumination.
