"Some people appear to be offended by questions about how creativity works, believing that it is not possible for us to understand this... Creativity does not work by magic or by divine inspiration. We cannot explain it in terms of intuition. It is true, to be sure, that creativity involves intuition, but to say that does not tell is much, since the word 'intuition' is just a placeholder for some unknown psychological process, invisible even to creative persons. If we want to understand how creativity is possible... we cannot rely on appeals to intuition... In other words, we have to understand how intuition works."
From 'Creativity: How Does It Work?' (Margaret Boden)
I like the idea that we cannot perhaps truly understand creativity as a phenomenon, short of perhaps completely understanding what consciousness is (and that's a whole other conundrum!). We can, however, study the processes of creativity; perhaps separate the generation of a work or idea into stages. Even if it is only these 'stages' that are distilled, this information can still be used by an individual to better understand their own creative process, with the possible outcome being more productive generation of ideas (critical to the fashion industry, which typically thrives on fast turn overs).
