The "Outer" world

I wrote down a bunch of notes to myself while the class was going on. I'm going to try to write what I was thinking during the class and make it say what I wanted it to say. We began with a chart with one side being the "Self" and the other being "the outer world". In between was a cross with Art, Philosophy, Craft, & Science. We talked about "Will" power, motivation. Then the questions were asked, "Do I exist?, How can I prove it?, can you prove the existence of your body, mind...will?" I then asked in my head, "why do you think that you imagined the outer world, is it possible that something else "created" this outer world? Maybe you are just experiencing my outer world". Then you said the outer world exists based on my senses. How does this chart work? Are the "four" (Phil., Art, Science, Craft) in the outer world... in the self? I think we experience the "four" as a result of our existing energy clashing with the outer world. The "four" may already exist with in the self, but it takes the interaction with the self and the outer world to bring them out. Do you consider yourself spiritual? I feel we are energy formed by the earth, as a result of the earths cycle and recycle process. We act in negative and positive ways in order to keep a balance. When we die our energy, which is all we really are, gets recycled back into the earth to become part of the whole. We experience so much confusion while we "exist" as humans, because we are separate from the earth. There really is no self. We may feel we exist as the "self" for a short period of time. The word itself probably doesn't need to exist. If you stop thinking about yourself and enjoy this experience while as a human then maybe you would be less depressing. Of course then we wouldn't have this class that makes everybody question the "Self";{ What would life, while living, be like if the word self and the meaning we gave it, didn't exist? I think it would change a whole lot.
