If you need an appendectomy, it's unlikely you'll die during the operation.
That's because the surgeon has been trained in hundreds of years of best practices. From Semmelweis to the latest in antibiotics, she knows what's come before.
Not only that, but the scalpel she uses is the result of 1,000 iterations over the centuries. Every device has been sanitized based on trial and error from the millions of patients who came before you.
Surgery is an engineering project, and it's based on best practices. Learn from the past, don't ignore it.
Art, on the other hand, is something we value because it leaps. Art is more than engineering–art is the thing that might not work.
But even art is based on best practices. Just not as much.
The playwright better have read Bellow and Beckett. The conceptual artist should be familiar with Duchamp. The photographer and designer needs to know Debbie Millman, Robert Mapplethorpe and Jill Greenberg…
Ignore it if you want to, but learn it first.
