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
Guided by image In our minds, the drawings we had originally made for the columns and capitals were no more than first approximations of the final shapes. We assumed that we would work out the real shapes during construction, and left the inaccurate approximations on our drawings, just for the sake of the building permit. Fujita, used to working with architects in System B, assumed that whatever was on our drawings must be what we wanted, and must be implemented as drawn. Anybody who was making those column capitals, if they had seen this "double" capital, and had been free to make something harmonious, would have done it differently. But Fujita's people, in System B, did not know how to be guided by reality. They were guided by "image". So Fujita, in this situation, was not free to respond in a natural way to what they saw. They were trapped by the image-making process they were used to. But because of this, they doomed their own carpenters to a pretentious kind of slavery, producing whatever silly images they were told to do, without being able to ask themselves whether they were beautiful, and unable to use their own sense of reality to make them better.
