“Model building is the art of selecting those aspects of a process that are relevant to the question being asked.”

—  John H. Holland

Source: Hidden Order - How Adaptation Builds Complexity (1995), Ch 4. Simulating Echo, p. 146
Context: Model building is the art of selecting those aspects of a process that are relevant to the question being asked. As with any art, this selection is guided by taste, elegance, and metaphor; it is a matter of induction, rather than deduction. High science depends on this art.

“Scientific information is faced with the following problem. On the one hand, we have the world’s literature of science and technology, past and present, in many languages; on the other, and enquirer with a question. How to select, from a vast mass of words, the few that are the most closely relevant to an enquiry? It is this selection process that makes use of classification.”

Brian Campbell Vickery (1918–2009) British information theorist

“[There is a] basic problem … of building a mathematical model of thought processes, and in particular of those aspects of thought which are concerned with information and decision processes. The perceptron is one type of model -- a set of memory devices connected in random fashion-- which has not yet achieved useful results but certainly seems to be a promising approach. The self-adaptive feedback control system which goes beyond the normal servo function of controlling its output, and in addition controls the parameters by which it controls its output is another which has already achieved pragmatic results in equipment control. It may be that the question of self-adaptation is a key to the whole question of how the human functions in a decisioning situation. For in many cases the ability of the human mind to adapt itself to a changing and complex environment is beyond our present aims in model construction.”

“As is used in connection with systems engineering, a model is a qualitative or quantitative representation of a process or endeavor that shows the effects of those factors which are significant for the purposes being considered. Modeling is the process of making a model. Although the model may not represent the actual phenomenon in all respects, it does describe the essential inputs, outputs, and internal characteristics, as well as provide an indication of environmental conditions similar to those of actual equipment.”

“Science is art. It is the process of creating something that never exists before. … It makes us ask new questions about ourselves, others; about ethics, the future.”

Regina E. Dugan (1963) American businesswoman, inventor, and technology developer

As quoted in Virginia Tech Magazine (Summer 2013) by Denise Young; also in Digital Da Vinci: Computers in the Arts and Sciences (2014) by Newton Lee

“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.”

“Edward, Edward," he said with a patronising smile, "there are no unanswered questions of any relevance. Every question that we need to ask has been answered fully. If you can't find the correct answer then you are obviously asking the wrong question.”

“Those who are concerned with the arts are often asked questions, not always sympathetic ones, about the use or value of what they are doing. It is probably impossible to answer such questions directly, or at any rate to answer the people who ask them.”

“[There will be movement toward] behavioral economics… [which] involves study of those aspects of men’s images, or cognitive and affective structures that are more relevant to economic decisions.”

Working paper. <br class="br">Alm proceeds by stating: &quot;Given the essential role of psychological insights in the field, together with the obvious truism that all economics concerns “behavior” in one form or another, a more descriptive name for the field is perhaps “cognitive economics”, as recognized early on by Boulding (1958).&quot; <br class="br">1950s

“Every time one combines and records facts in accordance with established logical processes, the creative aspect of thinking is concerned only with the selection of the data and the process to be employed, and the manipulation thereafter is repetitive in nature and hence a fit matter to be relegated to the machines.”
