No offense, Mies, but in my opinion 'Form Follows Function' doesn't tell the full story. It's a powerful phrase, and it summed up the intent of design in the machine age, but it implies linearity in the design process. Mies' buildings are stunning works of art, and I would argue they were driven by more than function. After all, architecture is more interesting than pure engineering, in which form only follows function. I would argue that in architecture Form Follows Function and Function Follows Form, and it goes on and on like that in a somewhat circular fashion until the design problem is solved. Form and Function inform and reinforce each other. Although function certainly comes before form, recognizing the power of form and treating it as an equally important participant, and not merely as the result of function, can help to propel function itself to an entirely new level. That's how inventions come about, for example.
