A civilization makes progress by leveraging the achievements and observations of past generations. We compress history into words, stories, and symbols that allow living people to learn and benefit from the experiences of the dead. In the space of one childhood, we can learn what it took humanity many centuries to figure out. While animals may have some capacity to instruct their young, humans are unlimited in their capacity to learn from one another. Thanks to stories, books, and our symbol systems, we can learn from people we have never met. We create symbols, or what Korzybski calls abstractions, in order to represent things to one another and our descendants more efficiently. They can be icons, brands, religious symbols, familiar tropes, or anything that compresses information bigger than itself.
