There is absolute truth. Without absolute truth there is nothing for an artist to search for, nothing for a politician to fight for, nothing for current affairs shows to discuss… everyone’s just talking and no one is listening.
Absolute truth really goes against the grain of post modern thinking primarily because in the past zealots have claimed to own the whole truth when really they were just eating a very small piece of a large pie. Fear and judgment has ostracized people from the concept of absolute truth; but without it we ambivalently float around in an amorphous ether without any form of grounding.
Truth should not be confused with perspective. While there are many different perspectives, they are all really just different angles on absolute truth. Which is why there is strength in the perspectives of many, and why there is power and learning in listening.
