I don’t see any shortcut, so let’s keep on sharing ideas.</div><div><br></div><div>From what has been expressed, it seems to me that we need to go beyond predictability, consistency, decidability… </div><div><br></div><div>All of these are very powerful, so it makes sense that we would like to use models that are predictable, consistent, decidable, etc. to explain and understand phenomena. But as we have seen, models that stick to the limits of formal systems are insufficient to study complex systems, evolution, intelligence, etc. And we do have models of these phenomena, but then we cannot predict as we would like. Still, it seems to me that it is the only way to go. We won’t be able to create formal systems without their limits. We must change our worldview, to go beyond those limits.</div><div><br></div><div>Grounding this a bit, I can share related publications:</div><div><br></div><div>Gershenson, C. (2013).

One can find flexible and efficient solutions for problems, but then one must give up “certainty” (because even if our methods are predictable, they fail when changes in the world deem our models obsolete).</div><div><br></div><div>Gershenson, C.

And then we can explore “laws of information” that apply to everything we can express (because if you can express it, by definition it is information).</div><div><br></div><div>Best wishes,</div><div><br><div>
