I mentioned before how the universe is finely tuned. But not just the laws but it also seems that the cosmological constant is very finely tuned. Anthropic scientists had no other alternative but to consider an intelligent designer. That was the very last thing they wanted to do. So after awhile came the many world's interpretation that their are an infinite number of parallel universes. However again the need for a intelligent deisigner came about because some of those universes are likely to be very complex. So now their is speculation that we are living in an computer stimulation, this offers a natural mechanism. So as you see nothing can knock of naturalism. Naturalism is held as a position, and it more tightly defended when contrary evidence comes along like mentioned above. Of course, other contrary evidence is survival of bodily which their is vasts amounts of evidence supporting it. Also psi phenomena and other type of phenomena such as stigmata etc.
Here's is an interesting pdf lecture by Alan Gauld on memory traces.
At the end of the lecture Alan Gauld conclusion is follows
An viable theory of memory will accommodate:
1. Top down rather than bottom up. Laws characterizing the system as a whole, rather than the whole being derived from the parts.
2. Memories cannot be tied to particular anatomical loci. Memories can be transferred to different parts of the brain.
3. It will regard nerve tracts that transmit nerve impulses to one part of the brain to another not as conduits for the transmission of 'information' in the loose sense commonly adopted by psychologists, but as means by which spatiotemporal patterns of activity in different regions may be fined tuned to create overarching patterns.
4. We cannot regard the matter as decided and clear....work in progress
