I take the aviation adage that the price of safety is constant vigilance. In other words, something which might to the outsider look easy, really it’s exceedingly difficult. And paradoxically, sometimes the simpler a building looks, the more complex the process behind it. It’s like the saying about a poem or an essay. It’s infinitely more demanding to create a poem than it is to write a long essay. And I use the analogy of the iceberg. The building — the built end product — is the tip that you see above the water. What you don’t see are the long exchanges, the process. You don’t see the designs that you’ve created, the teams, the options that have been pinned up that have been rejected. In the case of the Reichstag, you don’t see those long meetings with 65 representatives of every kind of political party who have been brought up to disagree professionally. If they’re not disagreeing, they’re not doing their job. And for the first time, they all have to agree on something. And they’re running off, and you know they’re going to the press, and you know that there’s going to be an attack in the press.
