We have made tremendous progress in many fields. We now know a lot more about the galaxies and so we do about sub-atomic world. And this progress is being accelerated by the tools that have eolved rapidly in the last few decades to allow us to collect, store, distribute, share, and represent data. We have to made enormous progress in information and communication. We even have developed tools to represent knowledge.
A question keeps bothering me, however. Have we really improved in our understanding of knowledge? Or are our tools for understanding knowledge are still very much as they were several decades ago before the rapid progress in dealing with data started?
I feel that our understanding of knowledge is weaker than our understanding of most of our knowledge. And this could only change if we develop a science of knowledge — a science that uses our current knowledge about other fields to understand fundamental knowledge ecosystem.
