Here is my metaphysics:

I believe in max tagmark` s level 4 multiverse, or some variant of the same basic idea.

There are no concrete objects( physical objects). There are only mathematical structures, or maybe informational structures( algorithms).

The feeling that we experience "physical thing" comes about from the first-person subjective experience. Thus, i think this feeling is an illusion in the same way that some people see the color "red". "red" is not a essential property of the red object, but as something that is filled in by our cognitive capacity.

People are informational, or mathematical substructures.

As far as i know, there are two people share my idea. They are steven landsburg, and Max Tagmark.


Am i convincing? Do you agree? If not, then why?

Now, there's a classic (ancient Greek) idea.
I think we are what we are, a physical, gritty thing,
that mathematics is entirely a tool of human abstraction,
and that we easily and instinctively project patterns
into anything. Thus the common thought (psychosis,
technically speaking) that math makes the universe.
Mathematics becomes God.
The gambling industry is based largely
on the human habit of seeing patterns in the random.

If you say math is a pattern, but i can ask you where these patterns are. You might say these patterns are just patterns, but patterns are only pattern when you have objects. If you agree it is about objects, then the question is what that these objects is suppose to be. It cannot be physical objects. Where is the number 3 located in space? So, it cannot be physical. Thus, it has to be informational, or mathematical objects. eg: what is an electron is nothing more but the information used to specify it. Where it is located? If it is spin up, or down. what charge is it etc. Onces, you specific an electron, then that is all there is to an electron. In fact, you can make up a description of an object with weird properties, and there would be a universe for it.

I would tend to think that the number 3 is located in the entirety of space. In other words, if it were visible to us, we'd see it (along with every other number) occupying every place in the universe. (This belief resembles Penelope Maddy's ideas, I think.)

I believe everyone of Max Tegmark's level four mathematical structure is a potential universe that may instantiate into a concrete universe like our own. Most of these level 4 universes, however, probably don't blossom into anything like our universe.Most of them, I assume, are stillborn.

It's hardly your idea; it is actually a trivialized version of mine ;o) It is the only a consistent position once someone takes these ideas seriously and I do.
