There is no ultimate ‘truth’.
Furthermore, to strive to search for ‘truth’ seems to be a waste of time.
We can strive to discover deeper self-knowledge about ourselves, and perhaps more ‘truthiness’ about the world. But all of this “truth” is subjective.
Then what are we to do with our lives?
A simpler goal: strive to make beautiful artworks. To determine whether something is beautiful in our eyes is far superior than to search for “truth”.
The visual philosopher
Perhaps we as photographers should better be seen as “visual philosophers“. We define beauty and judge beauty. We create beautiful art-images/objects with our cameras, how we process our photos, and how we display our images.
