I'm of the opinion right now that what we call "design" and "architecture" is really just the science of finding stable habitable zones in high-dimensional problem spaces.
What's cool about Alexander's work is that he makes a great case that this stuff is objective phenomena that can be studied!
I'm planning to write much more about Christopher Alexander on my own blog in the future, but meanwhile I can recommend Dorian Taylor's excellent works:

I gave a talk on this subject at DDD Europe this year, so keep your eyes out for "Timeless Way of Software - Taylor Troesh" on their YouTube channel :)
