Mind and body seperation within the confines of cartisian dualism

1650 and Cartesian philosophy has swept Europe and most of the post medieval world. Before this the concept of thought and self was confined to the pervue of the Catholic church.

"there is no quantum world. There is only and abstract physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature."

The Copenhagen Interpretation regards the waveform as not real. The alternative interpretation which accepts the same probabilistic view ans teh Copengagen Interpretation but regards teh waveform as real will be referred to as the State Vector Interpretaion.

Waveform Collapse The Copenhagen regards the waveform as having no reality and is only an aid to calculating probabilities. Consider teh following experiment:

A coin is to be thrown from the dark onto a table top. The observer cannot see the coin so teh best description he can produce is  &Psi; =(|heads>|tails>) &omega;  The coin tumbles onto the table and settles heads up. the best description of the coin is now  &Psi; =(|heads> &omega;  At no time did the description affect the outcome of the experiment and so in this sense it has no reality and the "collaplse" of the waveform :Psi holds no mystery.

The coin exaple is also misleading. We are quite happy to accept the "non-reality" of the waveform because we "know" the coin's position and teh momentum are in well defined states that could be measured, and if the appropriate calculations performed, we could determine in advance which way up the coin would land. The Copenhagen Interpretation on the other hand says the waveform is all that is posible to ever know babout the experiment.
