SOCIETY OF IDEAS:: INFORMATION OR KNOWLEDGE, UTOPIA OR REALITY?

Society is a basic concept for us, who live that way, but we still do not learn to live in society harmoniously. Treating ideas is very important too, because ideas are many and come from many places and by many people. But why with so many ideas the world is still unjust and suffering?There is also the intention to differentiate information from knowledge. Some people think they are the same thing. Are they? I assume that if they were, they would not be two different words. Finally, I consider it important to deal with the concepts of utopia and reality and the relationship between them.
