FW: A tree in a forest

There's the classic question of "If a tree falls in a forest and no one is around to hear it, does it still make a noise?" But I think that a better question is "Does it even exist if no one can see it?"
A person is both the subject and object. "I" observe "me". As long as I am aware of my existence, I am an object. I am looking at myself. When I think, I'm talking to myself. And the things that I do depend on how I see myself. When I make decisions I have to think of myself as someone else might think of me. When I go to a job interview, I have to think about what my boss might expect me to look like or act like, or how my boss might be expecting me to talk. I have to think of all those things, and when I do that, I am observing myself. I become some imagined "other" that is watching me get ready and making judgments about me. I develop a dual personality that no other living thing has. I am two people, one subject, and one object. So if I somehow stop observing myself, I lose the ability to make decisions based on society. But I can't do that because humans are inherently social animals. Therefore, my existence depends on my ability to step outside of myself and control my actions from an external point of view. Consciousness can't exist unless there is an observable object. Reciprocally, no object can exist without some agent that can observe it. A human is the only living thing capable of filling both roles at once. That is why we are the superior life form on the earth. Nothing else exists independent of exterior forces. So if there is nothing in a forest that is capable of observing a tree, then the tree cannot exist. The idea of a tree can exist in the head of some animal, but the tree itself is no longer real, because nothing gives it reality through consciousness.
