Discovering the Important Perceivable Truths, and Being Realistic About What We Know
      No one has yet had a good understanding of the important parts of Perceivable Reality for reasons previously discussed. Perhaps Socrates or Aristotle or other outstanding intellect had a fair understanding because the evidence concerning the important Perceivable Truths was much less extensive back then and the Perceivable Truths were much simpler. Certainly Socrates was well aware of the existing limits of human knowledge. Probably Galileo, Newton, and Poincare, who had good understandings of the evidence of their times, had fair approximations of key Perceivable Truths. They were aware of important evidence and theory that few others understood.

      Today the evidence is far more extensive and there are more alternative views based on the evidence. Studying all this evidence and the corresponding alternative views is much more time consuming than in the past. Today a good approximation of the important parts of Perceivable Reality is best achieved by teams of people who are each an expert in one or a few of the alternative views of the related Perceivable Truths.

      However, experts who are certain that the alternative view in which they are skilled is the one correct interpretation of all the related evidence may be unable to reason objectively. They may not want to learn about evidence that shows that other alternative views have equal or better likelihood of representing Ultimate Truth. People wanting accurate perceptions must keep in mind the evidence about human nature and the history of intelligent people who believed in views that we now know were wrong. We need to keep aware of our biases that make us prone to adopt certain views, and that people tend to equate their views with Ultimate Reality. By nature, people are prone to like their own ideas or ideas they learn and teach. We need to keep in mind that plausible views can become implausible due to new evidence or better interpretations of existing evidence, and that many of our views would look foolish if we had good understandings of Ultimate Reality. Only then can experts have reasonably objective thinking that permits them to work together to determine realistic probabilities for the alternative views comprising a Perceivable Truth.

      Most people who are interested in understanding nature and improving education and humanity would be interested in the probabilities that teams of experts from around the world assign to the alternative views of the Perceivable Truths about the key aspects of Ultimate Reality. Probabilities could be assigned by more than one team to gauge how well the probabilities accurately reflect the evidence. Such a project could help people in all cultures recognize that Ultimate Reality is elusive and that humanity needs to make the best of our poor understanding of Ultimate Reality -- and that adopting unrealistic perceptions of reality that are inconsistent with evidence and logic is probably not the best way.
