It is a mistake to seek universality when dealing with semantics and ontologies. The world is perceived and understood differently by every witness.<p>The solution is to allow every agent to either support or disapprove of every semantic statement. This way, the same query will output different realities depending on the agent&#x27;s opinions, preferences, and network of trust.<p>Imagine a knowledge base where Jesus statistically both exists and doesn&#x27;t exists, depending on who wants to know. A knowledge base where some food item is both a pizza and not a pizza. There&#x27;s no way around it, and this will become the start of a new semantic marketplace.
