For Ludwig Mies van der Rohe, who, if he didn't say "God is in the details" first, said it famously enough to get the credit, perfection lies in the unity of the overall design with the smallest aspects of how that design is executed. The IIT campus is beautiful, whether in plan or on foot. Crown Hall, its jewel, is beautiful to look at and to be in. And when you get right up close to it, and examine the choice of glass, the choice of steel, and how the two materials meet each other, those things are beautiful also.
Watch a graphic designer spend hours kerning type, or a film editor cutting in take after take, or a writer polishing a fifth draft. They're looking for perfection because they know God is in the details.
So where did the devil come from? I suspect he came in, as he often does, in the bags of money. The devil is in the details for business people, who know that even small things mean the difference between profit and loss, success and failure, job or the unemployment line. It's not about the quest for beauty, it's about the avoidance of mistakes.
No moral, just a reminder that the rhetoric you choose has consequences. As you struggle with details on your next project, are you searching for beauty, or trying to avoid screwing up?
