I think it's worth clarifying what we mean by rational - reason is a relative thing after all, shaped by upbringing. For instance, the great rationalist Descartes reasoned the existence of God and the Soul
a priori, and saw empirical evidence as inferior because of the involvement of the senses which suffer from the problem of Illusion.
Personally, while I tend to side with what the evidence supports, I certainly do not look down upon those with beliefs in alternative medicines and the like. Perhaps certain practices only work with certain people? It sounds unlikely if you consider it from the viewpoint that all human beings are built in similar ways, but we don't know that is an absolute fact.
Hume wrote about how we can never fully understand causation nor justify induction after all. Just as we can never fully understand why when we kick something it makes a sound so we can never fully understand how and why the body works.
Besides - when you think about it there is very little
reason to believe in an external world; our belief in it is the result of our past experience, of inferring cause and effect. In truth the evidence - our sense data - merely points towards, perhaps, us being brains in vats and that is all. Our memories can be doubted - maybe all this empirical evidence was recorded wrongly? Maybe the world was created ten seconds ago and we've been given a load of false memories. We cannot say for sure either way! The only thing we can be certain of is that with which we are directly acquainted - the perceptions we are having, be they real or not.
So I am taking on faith that our perceptions of the world are accurate representations of it externally

Absolutely right. Studies have shown that anxiety and pain are linked, and that reducing the anxiety (by having a positive outlook, knowing what to expect after the operation) will reduce the pain afterwards.

for example, who am i to sit next to a little old lady with cancer and say to her "oy luv, don't bother praying...it wont work..."
Actually, it's quite likely that it would work - a sense of autonomy and being able to affect one's environment and future have given people with terminal illnesses longer to live. Not by much, granted, but longer than they might have done without it.
So from this perspective although there may be no rational reason to believe in homeopathy being causally responsible (independent of the mind) for helping somebody to get better faster, it is quite rational to embrace a procedure provided you genuinely believe that it will help you - because it will, indirectly, through your belief in it.
Anyhow, I guess I'm not really adding anything to the debate... none of you probably exist anyway
