How can a thought exist apart from its thinker? One can imagine this, but philosophy does not deal with imagination, only with known facts. The notion that thoughts are set out into space and that others tune into them is based on the illusion that mind is in the body or brain, whereas the reverse is true. Has anyone ever measured the mind and shown where it started and ended? The very notion of the world is within one's mind. This shows that he cannot say that thoughts are outside the mind merely because he believes they touch somebody who is hundreds of miles away. There is no more separation between thoughts and thinker than between dreams and the dreamer.
