Without trying to sound like a cocky academic, everything is relative haha. What is value and how someone defines it, depends entirely in each individual's POV. Same applies for the 'ultimate truth' althought I have somr serious doubts about the possibility of something like that to exist, since history does always seem to complicate things ;)

So I think it all comes down to your everyday decisions and as the majority of them (hopefully) deals with the people around you, I believe that the way you honestly and consciencously treat others reveals a big part of yourself.
