We create the new not generally through some mad moment of inspiration in fictionalized accounts of ancient Greeks in baths (though the conditions for this can be forced into existence), but by putting things together that do not normally go together; from taking disciplines (or curriculum areas) and seeing what happens when they are forced into unanticipated collision. […] The mind, at its best, is a pattern-making machine, engaged in a perpetual attempt to impose order on to chaos; making links between disparate entities or ideas in order to better understand either or both. It is the ability to spot the potential in the product of connecting things that don’t ordinarily go together that marks out the person (or teacher) who is truly creative.
If only for this quote, the book Dancing about Architecture: A Little Book of Creativity byPhil Beadle is worth checking out. /ht to Brain Pickings.
