I wasn't suggesting that there is anything more required.

I simply find it interesting that there is an aspect to the Universe which is not matter or energy or space or time. And it is an aspect which we perceive.

Are there natural laws which govern "pattern" just as there are laws of physics for matter/energy and space/time?

Matter/Energy cannot be created or destroyed, only changed in form. Does the same law apply to "pattern"?


How is there anything other than matter/energy constrained by space/time? Their representation in our brain is a physical pattern of neural network linkages, where changing physical arrangements of molecules create electrochemical potentials which can be activated to produce the energy pattern that reflects consciousness of the information.

The physical structure of spacetime (see "The Fabric of the Cosmos" by Roger Penrose) is the source of the "laws" that determine the movement and arrangement of the particles of mass/energy it contains (Mass tells spacetime how to curve, spacetime tells mass how to move). Models such as relativity, chaos theory, quantum mechanics and string theory are attempts to understand and explain these underlying laws, but I don't think any of them require additional laws or a non-material aspect for patterns to form or information to exist.

The laws may be quite different in other universes. The value of the constants that specify and control our universe may be the result of some overall law that governs the multiverse (if it exists), randomly determined in the big bang, or they may have evolved concurrently with spacetime.

Of course patterns can be destroyed. Just rearrange the matter/energy into a chaotic form instead of order. When a hard drive is wiped, the only copy of a book is burned, the last dodo is eaten or the tribe's oral historian dies, the information contained in their physical patterns is irretrievably gone.

There is no law that conserves patterns, and as long as entropy increases the universe is happy.

A written word is not a written word until it’s interpreted as such. Prior to that it’s just black marks on paper, but it’s not even that. Whatever we call it that’s not it; the name is not the thing described.

A word is a word is a word. "Word" refers to the collection of sounds or other symbols that are used to transmit information from one human being to another. The symbols do not stop being a word while not being actively read, and do not magically "become" a word when a literate person perceives them.

You are mistaken in ascribing the source of information to the book. It’s like ascribing the source of the taste of lemon to the lemon, when the source of the taste is the brain-sense-organ.

The lemon, not the brain-sense-organ, is the source of the taste. Taste is just a symbol the brain uses to represent the sensory perception of a specific collection of acids and other chemicals. It then compares this information to its memory files and associates the "taste" with prior experiences of "lemon." The lemon must first exist in order for the brain to perceive its taste.
Quote:
Understanding the language has nothing to do with the capacity to create meaning and information with the marks or symbols. Interpreting the symbols as letters of the English language, is just one of many interpretations.

You're right. I understand English, but can create no meaningful information from your words here. How can someone who has no knowledge of the Cyrillic alphabet interpret an essay written in Russian?
Quote:
Information is a word with many meanings depending on context, but is as a rule closely related to such concepts as meaning, knowledge, instruction, communication, representation, and mental stimulus.

Although many people speak of the advent of the information age, the information society, and information technologies, and even though information science and computer science are often in the spotlight, the word "information" is often used without careful consideration of the various meanings it has acquired.

Which is why it is so important to look for context clues when reading, so that you can respond to the writer's intent instead of subverting the discussion into an argument about alternate meanings of the words s/he uses.

Although I appreciate the philosophical arguments being made here, I'm more interested in exploring the nature of "information" (or pattern), from a naturalistic base, rather than a metaphysical base.

I understand that the "taste" of a lemon is a concept and a perception within the mind, but I would like to treat the fact that the lemon itself *exists* as a given for the purposes of this discussion.

I'm assuming that "information" or "pattern" are actual things which exist in the universe in a measurable way, although I'm not sure yet just how to measure them.

I do not treat "information" or "pattern" as a purely perceptual thing because DNA creates life whether anyone is here to see it and understand it or not. And yet, there is more to DNA than simply the atoms which compose it; it carries a pattern, or information which results in more pattern (or more specifically, life).

To the very fundamental level of information, it would seem that man's ability to accumulate information to use it to advance our knowledge is key. Given that a lemon is a lemon, it depends on how man interprets the fruit through experimentation. Our ability to accumulate information from the very basic to how we are able to utilize a lemon today is the key. It's through our environment, culture, and language skills.

Man will eventually have the knowledge of how DNA works. Man had no knowledge of DNA hundreds of years ago. It's through the accumulation of information that we are now able to see the patterns of DNA with the assistance of language and science.

I'm not so sure if "measurement" of patterns or information is a necessary component to advance our knowledge about specific atoms at this point in time except for E = mc2 in a dynamic world.

Accumulate information? - information is only information when it can be put to use. We do not accumulate information. It vanishes and appears.

JJ did it the other way round.Which suggests disinformation.(BS for short).
