'Tain't so, Donuel. I'm saying that there is an intrinsic logic in the way the universe works. If I were proposing a theory of intelligent design, then I would say that some outside force made things in such a fashion that they work; or that the force made up the rules that things have to follow.

A round wheel rolls, and can perform many functions because of that property. A square wheel won't do the job. I can use logic and extrapolate from that function of rolling, and invent many things. And if I have an understanding of other functions and properties, I can combine those functions in a logical fashion and invent even more.

Trial-and-error is another method of invention, but it is usually far less efficient than logic.

And for almost every process that exists, we can usually eventually come up with a logical understanding of that process - and there is usually a logical interrelation between processes. The more we study, the more we find that things are interrelated.

The same goes for just about everything - everything seems to have a logic to it. The more I learn about the periodic table, the more sense it makes to me. Same with music, and the same with the development of language. In the end, it seems that it all makes sense.

So, what is the logic of a chord? Why does a major chord affect me the way it does, and why does a minor chord affect me differently? Why is it that I can tell when a note doesn't fit into a chord?

I do have a subversive reason for asking this question, Donuel. It has to do with a homeless shelter. I'm part of a group that worked very hard to transform a vacant county jail into a homeless shelter, and we're encountering a lot of opposition from people who live in the general area. They make all sorts of claims about the shelter endangering their lives and their children's lives. To them, it seems that the shelter is a cause of homelessness or at least a magnet that draws homeless people to our community. To me, that just doesn't seem logical - but I have to develop logical but diplomatic arguments to refute them. And in this Age of Trump / Age of the Internet, logic seems to be forgotten.

I figure I gotta hone my skills.
