I accept that there is more than one way to describe reality, and I accept the concept of supervenience, but where I differ with you (stubbornly, perhaps) is over use of the word "fundamental". The base property seems to me more deserving of being called "fundamental" than the supervenient property. If you were to give concise instructions to a god who wanted to build a copy of our world you could skip all the information about values etc. confident in the knowledge that all this extra stuff would emerge as long as the correct physical information was conveyed; whereas the converse is not the case.

Causation, and the relationship between causation and supervenience, is a philosophically very tricky subject. > Physics only describes physical properties.

In the same way, cardiovascular system activity is necessary and sufficient for the circulation of the blood. The difference between the two cases is that with circulation it is obviously so but with mind it is not obviously so: we can imagine the appropriate brain activity without mind but not the appropriate cardiovascular activity without circulation.

As well as the initial point I made about what deserves to be called fundamental (perhaps a definition is called for?), I don't see why certain categories are irreducible. For example, chemistry (physical transformations) could be seen as a special case of what you call mechanics (laws of the actions of forces), chiefly the electrostatic force. Also, it would be helpful if you could describe the underlying motivation and history of the model, or refer me to previous posts if I've missed them. -- Stathis Papaioannou --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
