I’m listening to Will Durant’s book, The Greatest Minds and Ideas of All Time, and I noticed this passage which help us understand why we get in such a pickle when we try and define knowledge.

“What is thought? It baffles description because it includes everything through which it might be defined. It is the most immediate fact that we know, and the last mystery of our being. All other things come to us as it forms, and all human achievements find in it their source and their goal. Its appearance is the great turning point in the drama of evolution.”
