We all know that the world is imperfect in many ways. We all know the works us made up of systems and that for the most part these systems are in balance. We know that natural systems are approximated very well by the mathematics of chaos, which means that they produce averages that can be approximated by mathematical statistics. We also know that all systems while tending to their averages occasionally thrown up values that are extremes. It is the extremes of values for systems that tell us that the world is made up of many seemingly ordered systems, but that we cannot know all the systems in operation and that it us this lack of knowledge that surprises us when we see errors and judge these to be failures in the system. These errors are evidence that there are other systems in play that we do not yet understand and have excluded so as to have a simpler view of the world.
Some may refer to these errors as evidence of the inherent randomness of all systems.
My position is that what makes human life and awareness is the presence of errors. Our human brain uses errors to learn and without awareness of errors we would be exinct long ago! We see and our senses work because of errors in the systems around us. To exclude errors would be to reduce the information our brain needs to understand the world more completely. Errors put us on new paths of revalation and discovery. Being able discern errors allows us to understand and correct them and to do that we explore systems at deeper levels to know more about them and how the work and can fail.
