.......and that support lies where?
(I wasn't aware that you are a multiversalist!)
I'm glad you asked.
I am indebted for part of my argument to an atheist internet philosopher who was trying to debunk the Thomist argument from change. The 'debunking ' went something like this. Modern science leads us to support the B theory of time and the block universe in which all of existence the whole of space time exists as a block in which there can be no change as such since past present and future are all 'blocked.
viewed in all their dimensions then, things which change are really kinds of static lumps representing there existence in the block universe. Like raisins in a cake.
Since change then is an illusion, then so is science, evolution, emergence anything that involves change.
So nothing actually changes and therefore process and mechanisms are illusions.
Since there is no mechanism there can be no actual thinking.
But hang on, something is experiencing change. Change is being percieved. It cannot be the brain percieving it since the brain doesn't change.
One explanation is that what is percieving change cannot be part of this block universe must be scanning through the lump in blocked existence that equates to our bodies' history.
So our consciousnesses must be as you say, outwith the blocked universe our bodies inhabit but there must be a specific connection with our blocked brains and it's blocked history with this consciousness which is doing the scanning and has to be outwith the universe.
The dilemma now is, for the brain functionists among you who see consciousness as an emergence out of brain processes, Does all that have to be dumped.....or do you have to dump the block universe model you use when arguing cosmologically?
The universe then in a block universe is not a scientifically observed process or processes but more like a piece of art.
Finally, now it looks as though Alan Burns has an argument I expect his detractors to grovel apologetically before him. Perhaps you Seb should eat a plate of luverly English eel pie and Mash and Hillside, an essex chap made to publicly declare Alan a 'Diamond Geezer'
and maybe those who think I can only think in terms of time's arrow should be grovelling to me. So get on those knees Davey.
