One is the loneliest number

Yesterday, I was going on about how I don't believe in anything anymore. However, at this point in time I have decided that there is at least one thing that exists. That one thing is me. I must exist. If I didn't, then there would be no way for me to come up with these thoughts. Whether or not there is a demon trying to deceive me, I must exist. There is no other way.

When I say that I exist, I mean that my mind exists. It is my mind that is creating these thoughts. I do not know if my body actually exists. The only reason I once thought it existed was because my senses told me it did. But like I said, those cannot be trusted.

It may sound strange, but this means that the mind must exist separately from the body. The mind is its own entity and is not created from matter. It can exist even without a physical brain in which to reside. My physical body, if it even exists, cannot perform any of the mental actions that my mind can.
