Lets say for example that in our world our knowledge is limited. That would mean that everyone would know exactly what everyone else knows. In our world today we have that freedom of choice to learn and gain as much knowledge as we possibly can. Knowledge is having information and using it to your advantage. When someone has full knowing, they understand in a complete way.
People have the knowledge of languages.
You have the freedom to find out and learn what it is you want. Discovery is another form of freedom. It is your right to discover things without there being a rule against it. Discovery is like a form of knowledge. The more you discover the more you know.
