Critical thinking oft ends up sounding bitter and negative when expressed in its written form. A master critic can praise and constructively critique a work but many critics are not masterful. Take Susan Sontag On Photography as an example. Her criticism on photography is highly de-constructive in my opinion, but masterful in its ability to provoke thought. Still, how anyone can read it and then pick up a camera afterwards without feeling self conscious to point of paralysis is beyond me. I certainly couldn’t. Being a thinking artist is not easy. I don’t know that I ever fully regained my feet after reading Sontag.
