Putting it crudely, every component in the brain moves because it is jostled by another component. This movement may coincide with mental activity that is apparently out-of-the-blue. For example, the brain states may progress S1, S2, S3 at times T1, T2, T3 and corresponding with mental states M1, M2 and M3. M2 may appear as a sudden idea with no apparent antecedent, but that does *not* mean that S1, S2 or S3 arise without antecedent. S1 leads to S2 and S2 leads to S3 in a deterministic way, entirely explainable in terms of chemical reactions. If it were otherwise then scientists would observe miracles at the microscopic level, and nothing like this has ever been observed. -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups "Everything List" group.
