"Everything we hear is an opinion, not a fact. Everything we see is a perspective, not a truth." (Marcus Aurelius, Roman leader, philosopher, Stoic).  Discuss.

I don't think absolutely everything we hear is an opinion, not a fact. Some things we hear may be opinion and other things we hear may be facts. We cannot classify everything people say under just opinion or a fact. If there were no opinions then people would not be individuals. If there were no facts, than there would be no trust.
