In my own life, I value truth, clarity and understanding over friendship, feeling good and bliss. Of course, usually they can be combined, but I don't mind understanding the horrors of the world much. That's the first step toward changing it for the better.
This is not for everyone, though. That's okay.
When I consider my life goals - enjoying my time, and reducing suffering - it doesn't seem entirely obvious that I should be valuing truth this much. Perhaps I could be more harmonious with less truth? On the other hand, it's also possible to live a fulfilling, harmonious life despite all the suffering in the world.
