Progression through creativity
Creativity
The following is a summary of an article written by Bret Battey in 1994 for a newsletter of Northwest CyberArtists. 
The popular understanding of the creative process is that it flows from idea to realization, meaning that someone gets a creative idea, executes it, and the process is finished, like so:

With this kind of idea floating around, it is not hard to understand why so many people do not see themselves as creative, or find creative tasks emotionally bruising. Anyone who tries to create with an expectation of a straight line from an idea to realization is set up for failure. 
It is important to realize that there is rarely a single idea or a single realization involved in a creative work. Creativity is, in fact, a feedback process characterized by oscillating stages of action and assessment. A more accurate portrayal of creation than the straight line might look like this:
graphic
In this diagram, the creative act occurs in the area between two poles: idea and realisation. Between the idea and its realisation there is an area which I have labelled "The Unknown". The tools for bridging the unknown are action (attempting a realisation of your idea) and observation (assessing your realisation in comparison to your idea). Based on your assessment of your first attempt, you adjust the idea and engage in action again to attempt a new realisation. Action and observation oscillate, the idea and realisation are adjusted and changed repeatedly until, ideally, the idea and the realisation are brought into alignment.
graphic
In this process, quite a bit of both your original idea and original realization can be transformed or discarded. At the end, however, the gap between the idea and a means of realizing it has been closed or narrowed. Now, given the same basic idea for a new creative act, one would find the unknown to be less of a chasm:
This is largely the case in 'popular' or established art forms, where both the idea and successful means of realization of that idea are within the vernacular of the culture. However, the magnifying glass in the above diagram serves as a reminder that for art forms in which the gap between idea and realization is quite narrow, often high value is placed on very fine details in the realization. The value here is on virtuosity - on having the highly refined skills and automatic knowledge needed to provide very tight turnaround between and idea and realisation.
New art forms tend to present a different picture:
graphic
Here, there tends to be a wide gap between the idea and the realization, because the idea itself is further from the cultural vernacular, and/or its means of realization are more difficult to establish. Here the value is not on virtuosity and precision as much as it is on the intellect and stamina needed to identify and negotiate a broad expanse of the unknown through many oscillations of action and observation.
One pole or the other can have greater weight. For example, in a case where someone has donated a lot of equipment towards an art project, the availability of the equipment might carry  more weight than the original idea, and the idea will conform to the implications of the equipment:
graphic
On the other hand, it is common in the experimental art world for the idea to have greater weight than the realisation. In their extreme, conceptual artists seek to remove the distinction between idea and realization altogether. Consider, for example, Takehisa Kosugi's 1965 Fluxus score Music for a Revolution: "Scoop out one of your eyes 5 years from now and do the same with the other eye 5 years later." The mode of creation might be represented in the diagram below, where realisation of the score would likely be terminal:
graphic
One can go to the opposite extreme: start with a very vague idea, execute it with raw intuition, then decide what the artwork is about. This is called 'publish or perish' or 'grantsmanship'. It is a common phenomenon in cases where people are asked to write or talk about their artwork after creating it:
graphic
Going back to more conventional creative processes, sometimes the tension between the idea  and the realization is too strong. We analyze and observe and think "It is NOT good." This looks something like:
graphic
The inner, critical voice is saying that there is no point in continuing given how far the realization is from the idea. With no fortitude to cross The Unknown, the creative process dies.
Sometimes, instead of exerting the fortitude to cross what seems like a very large chasm, we  may choose to engage in a quantum shift of either the idea or the means of realisation:
graphic
Here, for example, rather than giving up because of the width of the gap, the idea was shifted radically to bring it closer in line with the realization. This can be a creative act in itself. Working with rather than against malfunctions and errors in technology is a great example.
Now, what happens if you string together a number of creative acts and consider those as realizations of another idea-as another, larger creative process? You enter what cyberneticists and system theorists refer to a 'meta- change', that is, change that causes a change. By engaging in meta-creation spanning many creative acts, you challenge and adapt the life values  by which you form the ideas and evaluations described above
graphic
In other words, each individual act of creation can serve a larger act of creation rather than being an end in itself. In this context, one recognizes each artwork in a larger context, and art can become an agent of personal, and thereby societal, change. More established or commercial art forms tend  
to require less meta- creation, because the ideas and means of execution are largely externally defined. For those who have the option of being free from external requirements, meta-creation is not an option because ideas and criterion for evaluating realizations must be personally defined.

Epistemology describes how our knowledge goes from nothing to something. Hence, any account of reality requires an account of epistemology. At the level of the individual, science and religion are epistemologically similar. A scientific education, like a religious education is an education into a tradition. In science, like religion, authority is the justification for much of what is taught and in science the role of experiments is not demonstrative but illustrative. The individual's scientific knowledge depends on a web of trust permeating the scientific community which rests on scientific discovery as a progression of authorities. This is also the situation with regard to religious education and belief. The community and not the individual is in each case the natural unit of knowledge. 
Humanity has progressed over hundreds of thousands of years, but until about the seventeenth century, progress was a rare event. There were novelties but a person would not expect a whole sequence of improvements in his lifetime. Since then scientific progress has been continual, and in the advanced parts of the world, there has also been continued technological progress. Therefore, people no longer expect the world to remain the same as it is. 
One important ideal that inspired science was that of being true to nature, rather than to groundless opinions and superstitions, especially about divine interventions and the supernatural. This attitude became a common mode of thought in the Renaissance, which put the entire range of past ideas about the world, nature and human life under a magnifying glass, as it were, to see if they held up on closer analysis. In so doing, science also eventually helped create and establish the right to knowledge and free flow of information that characterises modern civilisation. We can consequently examine and evaluate ideas in a climate of opinion relatively free from fear, repression, dangerous conflict or dogmatism. This itself is no small achievement and the role of science in the history of the 20th century strongly suggests that it has in general helped to sustain what Karl Popper called  'the open society', even though it was also well integrated into the totalitarian systems of the Third  Reich and the Soviet Union. However, whether science itself embodies democratic values and whether its researches and other enterprises are directed democratically inclined is quite another matter. Great expansion has obviously occurred in the sciences and their related activities and social institutions. How much of this expansion really represents desirable progress and genuine enlightenment is the crucial question.
It is very well-known that there has been tremendous progress in the theoretical explanations, predictive abilities and manipulatory techniques and instrumentation in the natural sciences in modern times. All in all, it seems, knowledge of nature progresses on a broad front, especially in the basal sciences like physics, chemistry and biology. These are the most precise sciences and, since they yield many extremely accurate predictions, are regarded with good reason as producing certain knowledge, or at least the very best next thing. 
The natural sciences like geo-history, climatology and paleontology, which are not primarily experimental, have also made great advances in explaining and predicting events. Medical science, as distinct from medical practice, is an area where the understanding and control of the human body has made huge strides in many respects in the last few hundred years and very much more so in the 20th century. 
This being said, one must insist straight away that the huge advances made in our knowledge of the natural world should not be allowed to obscure the fact that there are very many gaps in that knowledge, many depths yet not fully sounded and also many phenomena of which the sciences have little knowledge, sometimes none whatever. Experts in all the above-mentioned sciences and in medicine still support as indubitable a number of central theories and prejudices that are under powerful and cogent attack from various quarters. As we shall see, short-sighted dogmas are still upheld by the inertia of scientific opinion, invested prestige and actual mediocrity or narrowness of intellectual scope. Scientific advances have not been without serious costs, both as to a wider understanding of the human entity and in terms of many unwanted side-effects on health, the quality of life and the environment. 
From its breakthrough in the Renaissance, physical science has been supported by those who saw it as an instrument of material and social change through technological knowledge. This accounts for most of the popularity it enjoys. Francis Bacon was referring to the empirical scientific spirit when he proclaimed that "Knowledge is power". It is power indeed, probably beyond Bacon's most far- flung imaginings... both physical, economical and social power, never forgetting military power. These are both reasons for science being supported and invested in by the various leaders in society.
Science made possible the demonstration of it's best hypotheses in repeated experiments. Its prestige arose from this, combined with the control of nature that gradually provided industrial technology with their advancements in material goods and useful inventions. Emergent European natural science studied nature, the physical environment of man, including the human body. Everyone knows how this has led to the improvement of physical conditions generally, including working conditions, health and human productivity. 
Very likely, the greatest rate of progress for the average person occurred around the end of the 19th century when safe water supplies, telephones, automobiles, electric lighting, and home refrigeration came in short order.
