What do we mean by consistency? I know some people are going to say: "Hey! That's Dan Flavin's act. Why in the hell is Irwin doing a Dan Flavin? Why is he suddenly so inconsistent – fluorescent one day and Cor-Ten the next?" The key to all of this is that we have to examples what we mean by consistency. And here the critical question is: "what do we use to measure consistency with?" If you measure consistency in terms of material, or gesture, then I will be found inconsistent. But, in all of the recent pieces and proposals, if you go to the actual site and look at it, you will find that the solution is absolutely consistent on the grounds within which it responds to its environment. This in turn is consistent with my development of the implications implicit in non-object art. Robert Irwin, Robert Irwin: A Conditional Art consistency
What's suitable for each unique condition What of machines and prefabrication? How do they compare? Well, the machine has its limits. We, using handcrafted methods, do things that machines cannot do. Of course, it's not fast like a machine. And in complicated areas like here, things wouldn't go the same using a machine as it would by hand. We use numerous variations of all these connecting and splicing joints. Using a machine, [the wood joints] can all be made uniform, but really, we need to consider whether that's a good thing. It's better to make each mechanism and joint by considering what's suitable for each unique condition. Akinori Abo, Kigumi House Chopped and disfigured contextmachinesconsistency
We feel it in our fingers In System A, there is no architect separate from the contractor. We are builders, simply. As builders, we have a direct feeling about construction. We feel it in our fingers, so it is down to earth. One result of this down-to-earth quality is that everything is somewhat experimental. We make experiments all the time. Sometimes we place a piece of wood this way. Another time, we may like to try it that way. Any time something new comes up in the design of a building, we are very likely to try and invent the best way of building it. This is not a great big invention. Just a simple invention, the way we might invent a way of tying a piece of string, to hold a broken toy together. It is just practical.
