Nelson, by coincidence., I was listening to your old skeptiko interview a few days ago. Interesting.
If idealism was 100% true, one would expect mind to dominate matter. So I think 'non-duality' philosophers are too quick dismiss unfashionable 'interactive dualism' which is our natural intuitive experience. Even the Near Death Experience suggest an expansion of consciousness where individuality survives death, rather than we lose individuality in the non-duality of cosmic consciousness. But idealism could be true at a deeper level, what some call a 'deep monism'. Just my 'thoughts'.
It is remarkable how strong the placebo effect is, considering the person is not really focussing on a potential benefit, generally just taking a pill. Even against some successful drugs, the placebo effect is often about one-third as effective.1) Placebo effect usually somewhat effective but usually not completely.
Philosopher Henri Bergson (a member of the Society For Psychical Research) suggested the brain was not evolving telepathy but filtering it out to create a clear sense of individuality. Imagine humans had 100% perfect telepathy, individuality would be lost. Nor should we expect telepathy to evolve strong in humans as they are such secretive, competitive creatures. We should perhaps expect telepathy to be stronger between, say a mother and child, and some studies indicate this.2) Sheldrake's telepathy experiments showed that telepathy in his test subjects was only a weak factor.
Thoughts?
