Thinking about Thinking

Photographing the camera, I think to myself, there is something here related very closely to that Zen conundrum of the eye that cannot see itself. That which sees is not seen. By a loosely parallel logic, is there any thinker that can truly think about itself? Can I think about my own thinking? A thought about a thought is not the thought thought about but the thinking of another thought entirely.

Looking at that last sentence, it seems trivial. Yet, let me see if I can apply it to something more useful, something of interest to more people than just me. There is being present, and there is thinking about being present. Where am I when I am thinking about being present? Where am I if I am not thinking at all? Why is being present more important than thinking about it? I think that there is no "I" at all, no presentness at all when I am truly present. So, in a sense, I am present only in thinking about being present, but I disappear when I am truly present.

Obviously, it took another camera to photograph this one. Maybe we are only present when others are around to witness. We are trees falling silently unless someone is in our forest to hear us.
