The document discusses several paradoxes related to social learning. The first paradox is that we all engage in social learning unconsciously. The second is that social learning has always occurred, even before recent technologies. The third paradox is that it is possible to learn without a teacher by observing others. The document also discusses the paradox of using new tools like social media to either create new learning conditions or do something entirely different. It questions whether the informal nature of social learning should be formalized or the formal nature of education should be informalized.
