Truth or Cynicism

We live in a relativistic society. Our society has lost its belief in absolute unchanging truth. We also live in a cynical society (no exception to be made for myself) that doesn’t trust anyone or expect anything good to happen. I think these are one and the same problem. When we lose our belief in absolute truth, then what’s to stop us from trying to do each other in. Then, loss of trust sets in, and therefore cynicism. Besides, if anything can be disputed, it’s impossible to have a supreme cause for which one commits one’s life.
