Rule forming and custom

Wittgenstein grammatical and material propositions. Rule forming and customs.

Is it that we cannot imagine anything new in our minds that are byproducts of our earlier thoughts plus material inputs from our senses.

Take for instance the discovery of benzene structure and the dream of Kekule, a snake eating its tail and atoms dancing in a ring. There is nothing new here, all are everyday happenings. Only thing is a new concept was formed using some old concepts.

What about Archimedes theorem? It was not a random finding. Ancient Greeks saw the relationship of 3, 4 and 5 satisfying the theorem. Like 2 apples plus 2 apples gives 4, they formed the rule 2+2=4.

But is it not possible to have a completely random form become a rule that everyone follows? The problem is this rule should be directed to some physical thing, only then it will be cemented as a rule accepted by everyone. Therefore all mathematics started somewhere physical, two or more rules created new rules and so on.

Is thinking only limited to this? What will be like if align comes to our world and say something completely align. Can we understand it. In a way it is better the don't come - so much of conflicts in the world where it is possible to communicate meaningfully, think of the chaos that can be created. Maybe that is why we don't find them - SETI program has failed.

So what is knowledge? Is it all inputs from environment thorough our senses, from birth, and creating links - concepts, to these inputs?

So we cannot have crazy ideas at all, we can have only known ideas or a mix of them.

This is very evident if you think of a computer. All what we get, is, what we put in, no more, no less. A sudden demon won't spring up from it, this we are certain. Our brain is not much different from a computer. Computer is a calculator it odd the same with our brain.

I should say something about art and music. What about these, aren't they create new things. We will not term as art or music anything newly created. We call it noise, visual or acoustical. If we cannot find patterns, it is noise. If we find patterns, then it is related to our earlier thoughts. Then we have art and music.

Our brain is an instrument smart in finding patterns. Much smarter than all current computers. It might change with the invention of quantum computers.

If this theory is accepted as correct, it will have far reaching consequences. A cyclone cannot create an aircraft. Random movements cannot create something very organised and structured. In the same way life cannot be created by random movement of atoms. Then this begs the question was there a beginning in the universe?

Sometimes what is wrong with everything like the conflict that can arise with this theory and big bang is because of our upstanding of time. We take for grant what we think of time without much thought. Suppose time is very different, and there was no beginning then it confirms this theory. Humanity in earth or life on earth can end with an astronomical action. Therefore life should exist in other places.

Problem of atomic propositions

Suppose the universe consists of facts.

Each fact can be a thought. Therefore can be represented buy a proposition. And each proposition consists of one or more atomic propositions. Atomic proposition cannot consist two or more propositions, but only one.

Consider inside a room - a room in a house, all the facts inside it are represented by a set of atomic propositions. Consider a proposition about a pedestal lamp is inserted, we can imagine a room without a pedestal lamp now converted to one with a pedestal lamp. Like that facts can be added or removed.

A room is a space. It is a subset of the space of universe. Room should be represented by a single big composite proposition that show every aspect of the room. This proposition will be the conjunction of many atomic prepositions.

The universe is represented by the universal set of all possible atomic propositions.

Any possible proposition is a conjunction of -(set of elements consisting of) atomic propositions.

Then logically the room can be represented by a subset of universal propositions. Wrong! Why?

Consider a proposition that represent Mount Everest. It cannot go into a room. Therefore any subset of the universal set of propositions won't fit a room. We might lead to think it is because of size, but no, Mount Everest cannot be moved to Pacific Ocean. This is an impossibility. Can American Declaration of Independence be inside this room? No. Though the physical size permits, practically it is an impossibility. So factors involved can be unlimited. If it is my room an expensive chair be in the room is illogical. But if the room is of a millionaire it may be possible. But further, a photograph of painting of Mount Everest can be in my room. So not all but some propositions regarding Mount Everest will be acceptable to represent my room.

It means that any subset of the universal set do not represent a subspace of reality.

A subset of the universal set is any number of elements of it taken together.

Room is a subset of universe. But it will not be a subset in respect of conjunction of propositions.
