Truth is the correct correlation between cause and effect.
Most of the time when we speak, while we are not technically lying, we are not speaking the truth either, what we do is actually proposing some probable connections between case and effect based on sequence analysis. We usually link events in a sequence such as that the first is the cause and the second is the effect. This is how we acquire what we loosely call “logic”. So logic is a form of truth.
How can we derive the truth from observable reality ?
Most forms of truth are in fact human conventions such as: 2+ 2 equals 4. This cannot be scrutinized any further, because that is its definition. So is that statement true or is it false ? While being a convention is also observable that if you start with action one putting two apples and another two apple in a bag the effect (second action) is that you now can count four apples.
So we try to see if a sequence of events is always the same, if every time B follows A than B and A are connected and A is the cause of B. However this approach can be extremely misleading. For example if person A enters a building and then after some seconds person B enters the same building, person A is not the cause of person B. Even though there is no cause/effect between person A and B, they still have a link, they perhaps work for the same employer. So still there is information in the sequence of events, but we may not know the relationship. Let’s not forget that this is how we define the “time” as well, the distance between two events in a sequence. So there may be other hidden layers of connection here between truth, time, cause and effect.
Can we derive truth in a different way ? No, as flawed as this approach is, following the sequence is the only way.
- The reasoning we do today is different from the reasoning we did yesterday and will be different from the reasoning we do tomorrow. The change in “truth” does not happen in days, but is for sure changing over time as more information accumulates. So we cannot really predict the future looking at the past.
- Since we live in the same observable reality we should arrive at similar/identical conclusions regarding the “truth”, as long as the same information is available to everyone.
