I don't see the necessity of a transcendent medium for causality if it is prior to spacetime. Several proposals for this have been discussed up on Strings, Branes and LQG, and no need for a transcendental substrate was encountered. I continue to think that philosophers should avoid making arguments based on physics unless they greatly broaden their understanding of the fields they are invoking.Tounesol said:It is clear from physics, as far as I can tell, especially in work on M-theory, that time and space are not fundamental. If this is so then phenomena having spacetime related properties are not fundamental either. If so then causally significant properties must adhere to something that is transcendent. This would have to be something inconceivable, like a wavicle, since we cannot observe of infer it, thus making the situation seem paradoxical.
