If we view the universe as being made up of signals rather than matter, what we call “reason” looks very much like a method for organizing signals.
We can visualize this and from our visualization imagine other ways signals organize.
We say something is reasonable when we cannot find elements that do not seem to be in place among elements that do seem to be in place.
In this respect, the term “aesthetic reasoning”—musical, visual, poetic, etc.—makes good sense. It explains how the elements of an artwork are put together, how they are organized.
Engineers generally reason in more utilitarian ways then artists, but there is a great deal of overlap between these pursuits.
Not all reason works only with tangibles and how to organize them. We also fit things together in our minds by what we normally think of as reasoning, inference, intuition, purpose, and so on.
In many cases, it is simpler and easier to think of signals than matter.
Signals organize into networks that signal other networks and receive signals from them.
A more “reasonable” network organization will work better than a less reasonable one. This type of network will tend to evolve.
