Here is some of a theory I am developing regarding truth as a property of information.
A strong concept of truth requires a strong concept of a mind-independent reality. A reality completely separate from individual conscious experience. This concept of reality would be equivalent to Kant's noumenal world. While we, as conscious beings cannot fully comprehend the nature of this external reality, we can ascertain that it has a certain set of real, consistent properties. For example, things with mass tend to fall towards the center of earth, our own bodies cannot pass through solid objects, gasses expand to fill their containers. We cannot know the ultimate nature of reality, but we can know that this reality gives rise to these consistent properties that do not change regardless of where we are, who measures them, or what someone's individual conscious experience is. For example, no change in internal mental state will allow your physical body to actually defy gravity.
The reliable operation of technology relies intimately on our reality operating with a set of very precise, specific self consistent properties. This is a statement about how our reality actually is.
Now thinking about Truth. Starting with this self-consistent external reality, how can the concept of truth be constructed? The way I have found to do this is by thinking about truth as a potential property of information. Truth is, in its essence, the name for Information that has something to do with this mind-independent reality.
Truth is Information that corresponds with reality. - The fundamental definition of truth
Now the question becomes what is the difference between information that has something to do with reality, and information that does not? Finding this difference will allow information that does correspond with reality to be separated from information that does not. This will allow truth to be found.
Here is the way to separate these two kinds of information:
Information that corresponds with reality will allow a conscious mind with that information to make an accurate prediction about reality, or to more easily interact with reality. If information does not allow an accurate prediction to be made about the world, or does not change how easily a person can interact with reality, there is no real way to know if the information is truth or not.
This is the basic premise of my theory of truth. Any feedback is greatly appreciated, as well as any advice on relevant work / materials I could read to gain a broader perspective on these subject. Thank you!
