In developing the model of the structure of knowledge, I embraced the risk of wandering off into the wilderness of marginal, perhaps inconsequential, modeling. This first part of the book addresses the structure of knowledge, whereas the second part deals with how knowledge grows, progresses, and advances. I had written several papers about how I believed human knowledge progresses. I had flatly rejected the evolutionary model of knowledge growth and progression. My views had congealed in the form of a different, clear, and consistent model.
