There is a section of the text about sequences that I did not quote from because there was no single quote that shimmered for me and I felt that it needed to be kept whole. This quote builds upon that missing subject and yet seems to have an independence. It holds, I believe, a key to a question I have reflected on (and I recall Pietro raising it too): what is the role / position of an expert (in any process). The answer Christopher Alexander seems to give is in creating processes that lead to unfolding of living structures … processes that are clear and simple enough for others to make decisions on their own. An expert creates processes that enable others to create.
Also, I can’t begin to emphasize how valuable to me the idea of differentiation is. In trying to plan things (a woodworking project, a deck, a house) I often feel stuck when trying an approach based on addition of parts. I am embracing this awareness and flagging it with an alternative … how to modify what I am doing into a task of differentiation. This makes me ask different questions. It reminds me to re-seek and reconnect with a sense of a wholeness I am trying to create and to look for that an anchor for what I am trying to do now WITHIN that wholeness (most recently I have attempted to to this with the physical construction of the Arduino powered automated dog-feeder I am building – both in its design AND in the way / order / sequence in which it is constructed / constructed).
“In any mass situation which requires repetition of houses, or repetition of apartment, or repetition of offices, it is good to bear the following in mind. Once generic patterns have been established, it is relatively easy to generate local individual variations in a genuine and practical way. You can do it be inventing processes … which give each individual the power to create the configuration of their individual house or apartment or office. Such a process can easily be constructed so that silly mistakes will not occur, and so that the process virtually guarantees that each person will be able to make a coherent design.
In general the geometry will be created by differentiations, not by addition or accretion, the parts given their dimensions by differentiating operations within the space of the land, or within the space of the room where the thing is being made.”
