I don't think your example of a symphony works very well as an example of something that has no physical existence. The sheet music is physical and exists, I have a lot of it myself. Also the instruments of the orchestra, the musicians and conductor. The sound is a result of the instruments causing the air to vibrate, that vibration is transmitted to the ears and there is translated into signals in the brain. Even the light by which the audience sees the orchestra might have some physical existence, I believe there is some debate on this point, but the light still effects physical objects and is reflected from physical objects in the process. The only aspect of the performance that can be said to be non-physical is the feeling of pleasure that the audience members get, or displeasure for a bad performance. I certainly felt some pleasure listening to Peter Schickele's analysis of the symphony. Of course the laughter, a result of that pleasure, was a physical expression of that pleasure.ReliStuPhD wrote:So Beethoven's Fifth Symphony does not exist?

A final thought, if you are going to suggest that the concept of the symphony in Beethoven's mind was not physical, there is some debate that even thoughts have some physical aspect or component, in fact some will argue that thoughts are just physical activity in the brain.
